The osgvolume example has support for altering the transparency and alpha clipping and the rendering techniques used at runtime. The interactive property support is provided by the osgVolume::PropertyAdjustmentCallback which you can reuse in your own program. See include/osgVolume/Property for the list of properties that are available to control the rendering. Press the 'v' key to cycle through the different rendering techniques. The techniques are standard intensity, light using normals computed from the volume, iso surface and maximum intensity projection. Press 'a' and move the mouse up and down to adjust the alpha clipping value. Press 't' and move the mouse up and down to adjust the transparency.

Re: [osg-users] help with osgVolume
Hi Robert, I'm really sorry. It's my fault, my dicom files contain inconsistent files they are from different parts of body. Actually osgVolume example program can correctly parse my dicom files when I manually put those associated dicoms in one folder. I downloaded a free software named dicomviewer, it can automatically identify associated dicoms and extract them for rendering. Attachments are two rendering results from osgVolume and dicomViewer. Can one of osgVolume's command-lines make the rendering result achieve the effect of dicomViewer(looks like more transparent)? In this project my teacher wants to build program kind like dicomViewer in first phase. So I want how many features osgVolume can achieve dealing with dicom. Thank you for your time and consideration!

Could you post an example dicom datasets that illustrates the problem? Also post screenshots of the problems. Or it is because the dicom plugin uses ITK but not DCMTK? How can I know whether the plugin use ITK or DCMTK, How can I switch between them? I don't know whether you've built the dicom plugin, or whether it's built against ITK or DCMTK. Both ITK and DCMTK are libraries that won't be installed by default so you have to go and aquire them, be it from repositories such as on Linux or from published 3rd party binaries, or just by building the source yourself. Do you have either one or both installed? Is the OSG's CMake system finding these dependencies correctly?

[osg-users] help with osgVolume
Hello there, This is my first post. I'm a college student recently working on a project dealing with volume rendering. I use osgVolume to render two series of dicom files. But only one of them with MR modality can be rendered correctly, the other with CT modality cannot. My questions are: 1. how does osgvolume parse dicom image? using osg::ImageSequence or other external libraries? 2. since in my case osgVolume cannot render CT modality dicom files correctly, I think osgVolume cannot parse them correctly. So what parameters I need to extract from dicom file in order to correctly render dicom files? Slice thickness, spacing between slice or z axis? 3.I tried to read osgVolume source code. But it contains too few comments to understand. So can anyone provide some documentation, user manual or any advices? Thanks in advance. I'm a beginner with osg so these questions may be too trivial.

When you read dicom files using the dicom plugin you should pass the directory name that contains the dicom files and it'll load them all, place them into a single osg::Image and set the dimensions correct so that osgVolume can set up the location of the volume brick properly. 3.I tried to read osgVolume source code.

[osg-users] [osgPPU] osgPPU Terrain Bug
Hi Art, I believe I have encountered a bug in osgPPU and using terrain. I have included code and a small terrain terrain file with this post. Would you please test what I am testing to see if you, also, encounter this strange anomaly? The problem: 1. Whenever I use terrain (a .ive file with it's associated directory) and I enable a pipeline, when I rotate the scene, the camera locks at horizontal. Then I keep trying to rotate the scene and eventually the camera unlocks and I can continue rotating the scene. 2. the pipeline in my included example is simply a pass-through pipeline. No Effects are applied. 3. If you 1) zoom into the scene a little the slowly rotate the scene to bring the camera horizontal to the terrain, the camera will freeze. 4. keep rotating the scene and eventually you will see the underside of the terrain. If you rotate the terrain too quickly, you may not notice this anomaly. However, in my program, I must be able to make the camera horizontal to the terrain and then from that horizontal position, title the camera up and make it look at the sky. I can not do this at this time. I believe the issue is somewhere in the pipeline unit code because when I deactivate the pipeline and simply view the scene without a pipeline active, this anomaly does not occur. The size of the terrain file does not seem to matter, either. The terrain I have included is DTED level 0. I retrieved my data from http://geoengine.nga.mil/muse-cgi-bin/rast_roam.cgi and 34.65000 lat, -98.8 lon will get you some dted data that can be used for further testing. However, you will have to convert DTED to an ive. I did that with gdal and some other tools. Would you please investigate this anomaly and tell me what you find? PS the terrain and example code file are too large for this posting. Here is the URL to where they are: http://drop.io/exOsgPpuTerrain Thanks Art.

[osg-users] [osgPPU] A Dynamic Pipeline
Hi All, does anyone know if it is possible to build a dynamic pipeline? I need to be able to build a pipeline after my scene is already up and running and the first frame loop has already occured.

Re: [osg-users] [osgPPU] A Dynamic Pipeline
Hi Art,
hum, ok. Here is the problem I am having:
1. In my application, I build my scene display it.
2. In building my scene, I build my pipeline and associate it with my scene.
My blur effect is working at the start of my application.
3. My initial view camera is looking down at my terrain.
4. Later, I move the camera programmatcially - not with the mouse - to a new
location within my scene. That location is still on top of the terrain and not
below my terrain.
5. After moving the view's camera, I no longer see anything in the scene I once
saw. It appears that no updates within the scene are displayed any further
within my view
If I remove the osgPPU pipleine altogether, my application works as usual. My
goal is to turn-on my blurring effect after my camera has been moved to a
particular spot within my scene and not before then.
It is as if the final scene displayed in my view is the scene just before my
camera is moved and no further updates are recognised after my camera is moved.
The final image I see in my view is the scene just before the camera was moved.
below is the code that actually moves my camera programmatically.
ui_viewNumber is equal to g_uiPRIMARY_VIEW_NUMBER because p_sViewName
is related to g_uiPRIMARY_VIEW_NUMBER
Code:
void CCompositeViewerGtkmmExt::vMoveCameraToPosition(osg::Matrixd p_mtxdM,
std::string p_sGWName, std::string p_sViewName)
{
unsigned ui_viewNumber=uiReturnViewNumberGivenName(p_sViewName);
if (ui_viewNumber == g_uiPRIMARY_VIEW_NUMBER)
{
CSceneMatrixManipulator *manip =
dynamic_castCSceneMatrixManipulator
*(m_osvPrimaryView-getCameraManipulator());
manip-setByMatrix(p_mtxdM);
} // if prim view
} // vMoveCameraToPosition
do you have any idea what might cause the camera's attached texture to cease
being sent into the pipeline?
here's how I setup my camera for my main view
Code:
void CCompositeViewerGtkmmExt::vCameraSetup(osg::Camera *p_pocmCamera,
int p_iTexWidth, int p_iTexHeight)
{
osg::ref_ptrosg::Texture tex = otxConstructTexture(p_iTexWidth,
p_iTexHeight);
p_pocmCamera-setViewport(new osg::Viewport(0,0,p_iTexWidth,p_iTexHeight));
p_pocmCamera-attach(osg::Camera::COLOR_BUFFER0, tex);
// must write the cam output to a frame buffer object, else, nothing will
// appear on screen.
p_pocmCamera-setRenderTargetImplementation(osg::Camera::FRAME_BUFFER_OBJECT);
} // vCameraSetup
Thanks Art!
Cheers,
Allen

Re: [osg-users] [osgPPU] Trying to install osgPPU in winXP
Hi argosen I've gotten osgPPU 0.4 to work on windows like that. never had a prob w/ the CMakeLists.txt file, though. I used CMake 2.6 for windows - with the GUI. I executed the CMake GUI, opened osgPPU_040 as my source directory, choose osgPPU_040/build as the build directory, cleared my cache - Under the File Menu I believe - and then clicked the configure button once. CMake ran and showed me a lot of things in red. I checked off the box for installing the data so that the data files would be installed, eventually. I then clicked configure again, the red went away and I clicked generate. After that, I executed MSVS 2005/v8; opened the sln file found within the build directory what was allocated during configure/generate stage. I then chose to build all from within the solutions manager. I, too, did not get cuda to build but everything else did. I then chose to build the install probject, which actually installs osgPPU in your OpenSceneGraph directory if that is the way you set it up during the configure stage. Hope this helps.

Yes, svn trunk of osgPPU tracks the svn trunk of OSG. Hmm, I wonder how to handle different osg branches in future.

I'm not sure what new problem OSG 2.8.3 has created for osgPPU that didn't already exist with the OSG 2.8.2 release. Can you explain the problem? I believe the answer is this: in the developer version of osg, 2.9.7 (I do not see any access to version 2.9.8 ) there was a method added to the PixelDataBufferObject class called getOrCreateGLBufferObject(). This method is required by the svn or trunk version of osgPPU but it is NOT needed by osgPPU 0.4. osgPPU 0.4 compiles with 2.8.3 and 2.8.2 branch versions, no problem. I do not believe there is a new problem unless we mix the developer version of osgPPU with a branch version of osg and this is where I became very confused as I never knew the developer version was called trunk and the stable release versions were called branch. I was mixing the two trying to implement some of Art's latest updates in osgPPU.

Re: [osg-users] [osgPPU] Can't compile svn version of osgPPU against osg 2.8.3
Gentlemen, thank you. Now I understand. But, I still have an issue. I downloaded osg 2.8.3 from the Osg website as shown in the attached pic 1. I used the svn link as shown. Is this link the trunk of osg 2.8.3? Or a branch? i can not tell. I did the same with osgPPU. pic 2 From my perspective as an end-user, I do not seen anything that tells me that there is a branch version that is different from a trunk version. I have been assuming this entire time that both the svn versions of osg and osgPPU are the two version which are compatible with each other, as Art has been telling me. And I have used the svn versions as listed on each website with no success. I am still missing something. Can you please clear up my confusion? thanks, Allen -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=27106#27106 Attachments: http://forum.openscenegraph.org//files/screenshot2_903.png http://forum.openscenegraph.org//files/screenshot1_210.png ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] [osgPPU] Potential Error In Functionality of method findUnit() ?
Hi, I am working with the method, findUnit(), within the class Processor and I have come across something very strange: In the program, osgppu.cpp using the header hdrppu.h, I do the following in osgppu.cpp/Viewer::initialize(): Code: mHDRSetup.createHDRPipeline(mProcessor.get(), firstUnit, lastUnit); mProcessor-addChild(firstUnit); osgPPU::UnitBypass* ppuUnit = dynamic_castosgPPU::UnitBypass*(mProcessor-findUnit(HDRBypass)); osgPPU::UnitBypass* ppuUnit2 = dynamic_castosgPPU::UnitBypass*(getProcessor()-findUnit(HDRBypass)); findUnit() in both cases returns NULL or 0 but I know for a fact that the firstUnit is the HDRBypass Unit or UnitBypass with the name HDRBypass. However, when I issue this same findUnit command for this same unit within the KeyboardEventHandler::handle() method, it works. Here is my code snippet: Code: osgPPU::UnitTexture* ppu = dynamic_castosgPPU::UnitTexture*(viewer-getProcessor()-findUnit(TextureUnit)); osgPPU::UnitText* textppu = dynamic_castosgPPU::UnitText*(viewer-getProcessor()-findUnit(TextPPU)); osgPPU::UnitInOut* pip = dynamic_castosgPPU::UnitInOut*(viewer-getProcessor()-findUnit(PictureInPicturePPU)); osgPPU::UnitBypass* ppuUnit = dynamic_castosgPPU::UnitBypass*(viewer-getProcessor()-findUnit(HDRBypass)); Does anyone know why this is the case? There is no documentation on this anomaly and I need findUnit to work in my 1st case as well as the second case. Thank you!

Re: [osg-users] [osgPPU] Potential Error In Functionality of method findUnit() ?
Aah, I understand. I was hoping I was missing something obvious and
something simple.
In OSG there is a node visitor find type thing one can do. Below is some
example code I found. I have not implemented this code and I hope to find an
even easier method.
I agree, though, I should be able to search osg's node tree. But you brought
up a very good point I was totally unaware of: the pipeline is not completely
instantiated until runtime.
What I was attempting to do was to change a shader value that is sent into my
blur shader (the blur shader I got from your examples :) ) and now I have
learned that I must change that blur shader variable at runtime because the
pipeline is not fully allocated until then. That is very good to know.
Thanks for your help, Art.
Code:
osg::Node* findNamedNode(const std::string searchName,
osg::Node* currNode)
{
osg::Group* currGroup;
osg::Node* foundNode;
// check to see if we have a valid (non-NULL) node.
// if we do have a null node, return NULL.
if ( !currNode)
{
return NULL;
}
// We have a valid node, check to see if this is the node we
// are looking for. If so, return the current node.
if (currNode-getName() == searchName)
{
return currNode;
}
// We have a valid node, but not the one we are looking for.
// Check to see if it has children (non-leaf node). If the node
// has children, check each of the child nodes by recursive call.
// If one of the recursive calls returns a non-null value we have
// found the correct node, so return this node.
// If we check all of the children and have not found the node,
// return NULL
currGroup = currNode-asGroup(); // returns NULL if not a group.
if ( currGroup )
{
for (unsigned int i = 0 ; i currGroup-getNumChildren(); i ++)
{
foundNode = findNamedNode(searchName, currGroup-getChild(i));
if (foundNode)
return foundNode; // found a match!
}
return NULL; // We have checked each child node - no match found.
}
else
{
return NULL; // leaf node, no match
}
}
Cheers,
Allen

Hi Art, You are correct. I am definitely using 0.4 on Ubuntu 9.0.4. I'll be glad to try the svn version and let you know what I find. I just wanted to pass along this information just in case you had not been told of this situation before.

Re: [osg-users] [osgPPU] Would you please consider adding this example to your osgPPU examples?
You're welcome Art! :D I've got another example that is almost ready to be posted. It blurs an entire scene, shows the original scene and, finally, glows all objects in a scene and blurs that entire scene. I am having to do this for a particular project that is mimicking an IR camera which has really bad resolution and objects in the IR camera appear to be glowing while moving. I really like your osgPPU module! You have saved me a ton of work. 8) Thank you. :) I'll post my latest example, here, later this week and I'll check-out what you have included in the project, too.

Re: [osg-users] [osgPPU] Potential Error In Functionality of method findUnit() ?
Hi Art, I have downloaded the latest version of osgPPU from svn. I fixed one bug - it was easy, just a typo - but I have 2 other bugs only you can fix. Here is the listing: Code: 2%] Building CXX object src/osgPPU/CMakeFiles/osgPPU.dir/Unit.o /home/allen/projects/osgppu/src/osgPPU/Unit.cpp: In member function ‘virtual void osgPPU::Unit::DrawCallback::drawImplementation(osg::RenderInfo, const osg::Drawable*) const’: /home/allen/projects/osgppu/src/osgPPU/Unit.cpp:703: error: ‘class osg::PixelDataBufferObject’ has no member named ‘getOrCreateGLBufferObject’ /home/allen/projects/osgppu/src/osgPPU/Unit.cpp:705: error: ‘class osg::PixelDataBufferObject’ has no member named ‘getOrCreateGLBufferObject’ make[2]: *** [src/osgPPU/CMakeFiles/osgPPU.dir/Unit.o] Error 1 make[1]: *** [src/osgPPU/CMakeFiles/osgPPU.dir/all] Error 2 make: *** [all] Error 2 I can not find any function close to the name of this function. I have included in this post the updated unit.h file for your convenience. I hope it helps. When you say: After the unit pipeline is initialized the loops are resolved and hence afterwards a simple node visitor should be also able to find any unit. I understand the term, initialize, means when the application is running and not after the line of code: osgPPU::Processor *processor = new osgPPU::Processor(); Am I correct? And I will be happy to use the findUnit() command once you have corrected any and all bugs you need to.

return false;
}// handle

What I have found so far:
1. my texture area is NOT resized on output
2. attaching a new texture to my main viewer's camera does not appear to have
any effect
3. setting my processor to the main view's camera which I just altered, has no
effect
4. Once you set the camera for a processor unit, you can not access that camera
to get it's pointer and thereby gain access to the camera's attached texture
5. Once you attach a texture to a camera, you can no longer access that
camera's texture so setTextureSize() can NOT be called on a texture that has
already been attached to a camera
I am afraid of deleting my entire pipleline and rebuilding it as I have found
out that removing a child node within a pipeline or deleting a unit in a
pipeline crashes my application. See my code which I posted in this link:
[url]
http://forum.openscenegraph.org/viewtopic.php?p=26645#26645
[/url]
So, I have found no solution to this problem yet either. Do either of you have
code that you can share if you have solved this problem? I would appreciate
seeing your solution.
Thanks!

I am looking for the following in an introductory course: 1. introduction to understanding terrain manipulators specifically the Terrain, Node tracker and trackball manipulators; i.e. introduction to manipulating the scene camera 2. introduction to understanding billboards and how to use them 3. introduction to callbacks and how to correctly implement them for real-time simulation and dynamically changing scene graphs 4. introduction to osgEarth and how to use it to perform real-time interaction with a planet, real-time display of earth terrain using my DTED and CIB data - in fact, osgVP or osg Virtual Planets I've tried to use but am unable to get it to function on windows 5. introduction to placing objects on an earth model to produce a simulated town, city, scene with planes or other flying objects in the scene; I also need the ability to track those objects by attaching a trajectory path to the rear of those objects and have that trajectory line appear and lengthen as objects move in the scene 6. introduction lighting - how to turn on/off for nodes but especially for nodes dynamically added nodes; this should include blending effects 7. introduction to understanding osgPPU - I'm working with it now but further help would be great! 8. introduction to special effects such as making something blow-up on an earth terrain and show that explosion I must admit, OSG is so vast that it is hard to know what all I'd want to cover. But the above list is a start and I am after a good healthy introductory course to OSG. Private or public classes are fine with me. My company won't pay for it but I will if I can as it will help me to improve my career. The above list is the list of things I am currently doing in OSG and that I am struggling with to understand. I have about 4 years of experience with OSG but that is nothing compared to what I need to understand to better utilize this tool. I have just been introduced to blurring using osgPPU and, boy, has that been a nightmare! But I am finally getting something to work after 5 weeks of sweating and trial and error. Thank you Chris for your interest in my needs. Do you have any suggestions?

[osg-users] [osgPPU] dynamic of the pipeline
Hi,
does anyone know if it is possible to setup a pipeline such that I may turn on
and turn off a blurring effect during runtime?
For example:
camera-setViewport(new osg::Viewport(0,0,windowWidth,windowHeight));
camera-attach(osg::Camera::COLOR_BUFFER0, textureView);
camera-setRenderTargetImplementation(renderImplementation);
// setup osgPPU pipeline processor, which will use the main camera
osg::ref_ptrosgPPU::Processor processor = new osgPPU::Processor();
p_ppuProcessor = processor;
processor-setCamera(camera);
// setup unit which will bring the output of the MAIN camera,
// w/in the Processor unit into the pipeline
osgPPU::UnitCameraAttachmentBypass* ucaByPass = new
osgPPU::UnitCameraAttachmentBypass();
ucaByPass-setBufferComponent(osg::Camera::COLOR_BUFFER0);
ucaByPass-setName(mainCamOutputTexUCAB);
processor-addChild(ucaByPass);
// bypass With Blurring
//
osgPPU::UnitBypass* bypassWithBlurring = new osgPPU::UnitBypass();
bypassWithBlurring-setName(BypassWBlurring);
ucaByPass-addChild(bypassWithBlurring);
// bypass withOUT blurring
osgPPU::UnitBypass* bypassWOBlurring = new osgPPU::UnitBypass();
bypassWOBlurring-setName(BypassWOBlurring);
ucaByPass-addChild(bypassWOBlurring);
blurring ppu code...
osgPPU::UnitOut* unitOut2= new osgPPU::UnitOut();
osgPPU::ShaderAttribute* shaderAttribute= new osgPPU::ShaderAttribute();
{
osg::Shader* shader= new osg::Shader(osg::Shader::FRAGMENT);
const char* shaderSource=
uniform sampler2D textureNameInShader;\n
void main()\n
{\n
gl_FragColor=texture2D(textureNameInShader,gl_TexCoord[0].st);\n
};
shader-setShaderSource(shaderSource);
shaderAttribute-addShader(shader);
shaderAttribute-setName(nomShaderAttribute);
shaderAttribute-add(textureNameInShader, osg::Uniform::SAMPLER_2D);
shaderAttribute-set(textureNameInShader, 0);
unitOut2-setName(finalOutputUnit);
unitOut2-setViewport(new osg::Viewport(0,0, windowWidth, windowHeight) );
unitOut2-getOrCreateStateSet()-setAttributeAndModes(shaderAttribute);
}
//exp 1 for blurring whole scene;
bypassWithBlurring-addChild(blurx);
blurx-addChild(blury);
blury-addChild(unitOut2);
bypassWOBlurring-addChild(unitOut2);
How may I turn on and off my blur effect during runtime? I have tried using
setActive but unfortunately, it only appears to work - within my pipeline -
when applied to the last ppu, blury, and I get a black screen. Using
removeChild() in any situation causes a runtime crash.
I am not sure if removing a unit from processor is the right path to go either,
because my units are children of other units and that would force me to
re-construct my whole pipeline dynamically during runtime. I can do that but
it is more work.
Any help would be appreciated.
Thank you!
Cheers,
Allen

Re: [osg-users] [osgPPU] dynamic of the pipeline
Hi,
Thank you Harash.
Another Way: The One you are using Keep a UnitInOut parallel to your blurring
channel. In the shader for his unit, just pass the Input to the output.
Connect the O/P of both to the UnitOut. Enable node mask of the preferred
channel as per requirement.
Do you mean?
processor = new processor()
processor-setCamera(...);
ucabypass = new UnitCameraAttachmentBypass();
processor-addChild(ucabypass); // gets texture from Camera
// OUTPUT to the Screen
// setup output ppu unit that is the size of the scene and is a
// tex to be rendered to the screen w/in the FBO.
osgPPU::UnitOut* unitOut2= new osgPPU::UnitOut();
Code:
osgPPU::ShaderAttribute* shaderAttribute= new osgPPU::ShaderAttribute();
{
osg::Shader* shader= new osg::Shader(osg::Shader::FRAGMENT);
const char* shaderSource=
uniform sampler2D textureNameInShader;\n
void main()\n
{\n
gl_FragColor=texture2D(textureNameInShader,gl_TexCoord[0].st);\n
};
shader-setShaderSource(shaderSource);
shaderAttribute-addShader(shader);
shaderAttribute-setName(nomShaderAttribute);
shaderAttribute-add(textureNameInShader, osg::Uniform::SAMPLER_2D);
shaderAttribute-set(textureNameInShader, 0);
unitOut2-setName(finalOutputUnit);
unitOut2-setViewport(new osg::Viewport(0,0, windowWidth, windowHeight) );
unitOut2-getOrCreateStateSet()-setAttributeAndModes(shaderAttribute);
}
// non-blur channel
ucabypass-addChild(unitOut2);
// BLUR-CHANNEL
Code:
osgPPU::UnitInOut* blurx = new osgPPU::UnitInOut();
osgPPU::UnitInOut* blury = new osgPPU::UnitInOut();
{
// set name and indicies
blurx-setName(BlurHorizontal);
blury-setName(BlurVertical);
// read shaders from file
osg::ref_ptrosgDB::ReaderWriter::Options fragmentOptions = new
osgDB::ReaderWriter::Options(fragment);
osg::ref_ptrosgDB::ReaderWriter::Options vertexOptions = new
osgDB::ReaderWriter::Options(vertex);
osg::Shader* vshader =
osgDB::readShaderFile(Data/glsl/gauss_convolution_vp.glsl,
vertexOptions.get());
osg::Shader* fhshader =
osgDB::readShaderFile(Data/glsl/gauss_convolution_1Dx_fp.glsl,
fragmentOptions.get());
osg::Shader* fvshader =
osgDB::readShaderFile(Data/glsl/gauss_convolution_1Dy_fp.glsl,
fragmentOptions.get());
if (!vshader || !fhshader || !fvshader)
{
printf(One of the shader files gauss_convolution_*.glsl wasn't
found!\n);
}
// setup horizontal blur shaders
osgPPU::ShaderAttribute* gaussx = new osgPPU::ShaderAttribute();
gaussx-addShader(vshader);
gaussx-addShader(fhshader);
gaussx-setName(BlurHorizontalShader);
gaussx-add(sigma, osg::Uniform::FLOAT);
gaussx-add(radius, osg::Uniform::FLOAT);
gaussx-add(texUnit0, osg::Uniform::SAMPLER_2D);
gaussx-set(sigma, gBlurSigma2);
gaussx-set(radius, gBlurRadius2);
gaussx-set(texUnit0, 0);
blurx-getOrCreateStateSet()-setAttributeAndModes(gaussx);
// setup vertical blur shaders
osgPPU::ShaderAttribute* gaussy = new osgPPU::ShaderAttribute();
gaussy-addShader(vshader);
gaussy-addShader(fvshader);
gaussy-setName(BlurVerticalShader);
gaussy-add(sigma, osg::Uniform::FLOAT);
gaussy-add(radius, osg::Uniform::FLOAT);
gaussy-add(texUnit0, osg::Uniform::SAMPLER_2D);
gaussy-set(sigma, gBlurSigma2);
gaussy-set(radius, gBlurRadius2);
gaussy-set(texUnit0, 0);
blury-getOrCreateStateSet()-setAttributeAndModes(gaussy);
}
ucabypass-addChild(blurx);
blurx-addChild(blury);
blury-addChild(unitOut2);
Now I have 2 inputs to unitOut2. How would I enable a node mask? I have
never heard of such a thing.
Thank you!
Cheers,
Allen

Re: [osg-users] [osgPPU] Help with glow example
Hi, Art, thank you for such details. I had studied the code and looked at the documentation on-line but I was still misunderstanding the basics of how to construct a pipe-line and how to inject scene camera data into that pipe-line. Your explanations have helped tremendously. allensaucier wrote: � Select � � Expand � 1. what line of code actually performs the glow effect? a. I am a novice with shaders and osgPPU b. I found how to increase the intensity of the glow within the shader source code; it is the * 2 effect on glowColor c. I can not find the line of code that actually performs the glow There is no direct one line or function. It is just matter of the algorithm used behind. For glow effect the object which has to glow is rendered separatly in a buffer. This buffer is then blurred (shaders) and added to the main view also in a shader. So you have to understand first how the algorithm works and then you will find the lines of code you actually need. Quote: � Select � � Expand � 2. Within the shader source code, the variables view and glow confuse me. Nothing within glow.cpp refers directly to either of these variables and so I do not know 1) how the glow effect actually happens. 2) how the different input to shaderSrc is actually differentiated between view and glow. Would someone please tell me? I have noticed that the resultShader receives input from unitCam1 and from blury which gives the view and glow outputs, though I do not fully understand how. See previously. View is the main view, glow is the glowed view. I believe the glow method is the actual combining of the Main Camera's output with the slaveCamera's output. This feat is still a mystery to me but it is really kool. I have two reasons for wishing to understand it: 1) I want to blur an entire scene as viewed by my main camera; 2) I wish to glow a dynamically instantiated and added node to my scene where the entire scene is blurred and that new node is glowing. I understood that the view and glow within the shader code were for two different camera inputs. Could you tell me how the shader knows which input is from which camera? This fact still completely eludes me. UniCameraAttachmentBypass do bypass camera's attachments (i.e. render textures) into the osgPPU pipeline. As I said before, every unit is a node computing outputs by using inputs. Inputs are always textures. So in order to bring it to the pipeline from OpenSceneGraph's cameras, we place this unit either directly under Processor or under UnitCamera. UnitCamera do bypass the osg's camera to the pipeline. It has no direct output and hence UnitCameraAttachmentBypass is required to get camera attachments and put it into the pipeline. Units placed under AttachmentBypass will use camera's texture as input. Question: when you say, UniCameraAttachmentBypass do bypass camera's attachments, do you mean that UniCameraAttachmentBypass sends a camera's output into the pipeline without modification? The word bypass means to completely go around an object and not deal with it at all and LEAVE IT behind you so that it has NO FURTHER EFFECT in the path you have chosen to go. However, to pass a camera's attachments into the pipeline means to take a camera's output and simply send it forward into the pipeline without modification within that unit. One more question: It appears that the main camera or any camera for that matter must have a texture attachment added to it so that that camera's output may be sent into a pipeline as a texture. Is this correct? Thank you very much Art, I really do appreciate your time and I appreciate you answering my questions. After I have completed my tasks, I would really like to send you the example code that I am building and see what you think and perhaps even publish my example with your approval. :) Cheers, Allen -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=26358#26358 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

I have continued to notice the use of processor as the beginning of the pipeline. When adding a child to a pipeline element, does that automatically send output to the child? 4. I have noticed that there are 2 camera inputs into the pipeline. One is the main camera directly attached to processor. The other is a new camera, slaveCamera, which is attached to unitSlaveCamera. What stops the main camera's output from going into the unitSlaveCamera? 5. what does osgPPU::UnitCameraAttachmentBypass mean? 6. what does osgPPU::UnitCamera mean?

Re: [osg-users] [osgPPU] Err Compiling cudakernel
Thank you Art cr333, I really appreciate your response. Hum, I will have to check CUDA_DIR and CUDA_INCLUDE. I never knew there was a cuda compiler. Now I know what nvcc means. I have checked my CMake configuration. I have included a pic of what cmake finds. 1st: I placed osgPPU in my Osg 2.8.2 build directory 2nd: I ran cmake on c:\OpenSceneGraph-2.8.2\osgPPU-0.4.0 These 2 steps produced the cmake output that I have included in my pic1. What is odd is that cmake tells me CUDA installation was not found but in my pic1, certain variables, FOUND_CUBLAS, FOUND_CUBLASEMU and others are found! And they are pointed to the correct CUDA directory on my system, C:\CUDA. When cmake tells me cuda is not found and the fact that CUDA_INCLUDE is NOT listed in my cmake configuration, does this mean that cuda based applications will not compile for osgPPU? And I assume that sinf/cosf/tanf are cuda versions of sin, cos and tan? Hum, I have not come across that problem as yet.

I have a question: I am trying to blur my entire scene. Is that possible with osgPPU? If so, would you mind showing me how? I can not find any examples of how to use osgPPU at the website - perhaps I'm looking in the wrong place. I am needing to blur both my scene and to have motion blur on objects within my scene that are moving. Thank you so much!

Re: [osg-users] Survey: Is there interest for an OSG Users Group at ITEC or I/ITSEC?
Hi, So, the questions are: 1) Do you go to ITEC and/ or I/ITSEC? (Please specify which one) If this type of event does not occur in Huntsville, AL, I would not be able to attend as my company does not support training or things of this nature, either. 2) Would you go to a OSG Users Group Meeting? I would definitely attend an OSG UG as I am still a novice in OSG after 4 years of struggling with it and would deeply appreciate meeting others who use this product and discuss how to use it more effectively let alone hosting osg training seminars! And I, myself, would be willing to help pay for the training seminars! And that would be out of my own pocket. But again, I would need an OSG UG in Huntsville, AL. Thank you for posing these questions. I really appreciate it.

Hi, Would someone please point me to an installation guide of osgPPU on Win XP, if one exists? I can not find one on the website. Plus, I am following the osg example of windows installation using cmake and when compiling, the project cudakernel does not compile because it can not find gl.h. Being on a windows platform with OSG 2.8.2 installed, I thought for sure osgPPU would use OSG's opengl files. It may but not for opengl. I'm using an nVidia 9600gt card. Are the openGL drivers/dev files susposed to be installed with the card installation software? Thank you!

Thank you Yann. Does anyone know how to install osgPPU on windows?

I had to install cudatoolkit from nVida - I'm running on an nVidia card: 9600gt. So, I used CMake on osgPPU to build an MSVS 2005 sln for osgPPU.

Re: [osg-users] recommendation requested for using osg with dynamic geometry
Hi, Well, if your goal is like mine, I have a solution but it is not the best I don't know a better one as of right now: 1. set up a data struct that holds your objects and info to update the object of in the object list my list is very detailed as there are other things I track besides the position of an object and it's orientation: light on/off, fog on/off, label on/off, etc... 2. I also hold a copy of the object's PAX positionAttitudeTransform w/in my object list so that I may look it up quickly w/in OSG's node tree to update it when I need to. 3. Implement a locking mechanism to LOCK the OSG node tree each time you wish to update a node w/in the tree Why? Because I found that updating a node or PAX as I call it outside of the rendering loop causes a crash because while I'm accessing my PAX OSG's render loop can also access that very same node a crash occurs 4. When I insert or update a node into the node scene, I lock the OSG node tree, perform my insert/update, and then unlock the node tree. This is not the best way, but it is the only way I know of at this time that allows me to updated nodes in a real-time/semi-real-time simulation environment. However, constantly locking unlocking the node tree does slow the system down and I do believe that there is a better way.

Re: [osg-users] Help: how to rotate view camera 90 degrees in relationship to terrain
Aaaah, that explains some of what I'm seeing. Hum... Using the TerrianManipulator is different from the trackball manipulator but the idea is the same: setByMatrix I have been assuming to capture the entire state of the manipulator and to properly situate my camera exactly where I want and at the rotation I want. Guy, I am trying to rotate the camera 90 degrees with respect to a local coordinate frame. The local coordinate frame is actually @ the edge of the earth (a sphere or ellipsoid) so the camera must be orientated on the terrain at a 90 degree angle to it. Thank you both for your response. I appreciate the help! J.P. Delport wrote: Hi Allen, the problem with setMatrix is that it cannot fully encapsulate the state of the manipulator. Internally the manipulator (trackball) uses a distance, rotation and center, but all these variables do not fit into a matrix. The manipulator can calc a matrix from the internal variables, but not set them properly from an input matrix. E.g. the view might look OK, but the rotation point is somewhere weird. Some pointers to the past: http://thread.gmane.org/gmane.comp.graphics.openscenegraph.user/8588/focus=8612 http://thread.gmane.org/gmane.comp.graphics.openscenegraph.user/19271/focus=19873 jp Allen Saucier wrote: Hi, thanks JP! :) I really appreciate your response.

[osg-users] Help: how to rotate view camera 90 degrees in relationship to terrain
Hi,
I am having some extreme difficulty in rotating my viewing camera 90 degrees
with respect to a local coordinate system.
Local coordinate system: (in geocentric measure)
mine is at the edge of the earth; i.e. i'm using a spherical earth. here is
how I compute the local axes:
fuctionName ( osg::PositionAttitudeTransform pax )
{
osg::vec3d objectLocation = pax-getPosition(); // where x,y,z are -678468.2,
-5405095.0, 3682910.3
osg:;quat qOrient = pax-getAttitude();
osg::vec3d up(0,0,1); // z axis of the earth or World coordinates
osg::vec3d x_axis = up ^ objectLocaction;
osg::vec3d y_axis = objectLocaction ^ x_axis;
x_axis.normalize();
y_axis.normalize();
osg::Quat qRotAboutAxisByDegree;
qRotAboutAxisByDegree.makeRotate( osg::DegreesToRadians(-90.), objectLocaction);
osg::Quat qNewOrient = qOrient * qRotAboutAxisByDegree;
s_mtxdIrCamPosOrientOri = osg::matrix::rotate(qNewOrient) *
osg::matrix::translate(objectLocation);
}
1. I know for a fact that the pax is set correctly with position attitude
because my objects are being placed on my terrain, which is georeferenced
terrain, correctly; i.e. they are perpendicular w/ the terrain and sit nicely
on it.
2. the above code snippet actually works for rotation about the local Z axis
and I am looking straight down at my terrain; i.e. directly down the local Z
axis.
3. I want to rotate the camera up 90 degrees and be looking down the positive
X axis.
4. I have tried replacing
qRotAboutAxisByDegree.makeRotate( osg::DegreesToRadians(-90.), objectLocaction);
with
qRotAboutAxisByDegree.makeRotate( osg::DegreesToRadians(-90.), x_axis);
and I get the camera rotated about some axis I am NOT sure of and I am looking
at the terrain from a peculiar angle, though I know not what angle.
5. I am using the TerrainManipulator as my scene matrix manipulator, if that
helps.
Would someone please give me insight as to how to do this? I would be greatly
appreciative as the solution is totally eluding me. :O
...
Thank you!
Thank you very much.
Cheers,
Allen

My CLASSPATH in Eclipse is: C:\osgvp-2.2.0-SNAPSHOT-src\libosgvp\libjni-osgvp\target\target_cmake\lib;c:\documents and settings\allen\.depman\lib; My PATH in Eclipse is: C:\osgvp-2.2.0-SNAPSHOT-src\libosgvp\libjni-osgvp\target\target_cmake\bin;c:\documents and settings\allen\.depman\bin; Semicolons are necessary on windows to replace the colons between path entries. For the life of me, I can not figure out what I am doing wrong. I know jniosgvpviewer.dll is findable and in my path yet the eclipse environment can not/will not find it.

Re: [osg-users] [ANN] OSG Virtual Planets, the core of gvSIG3D.
Ok, I have a partial solution :):)
Environment Tab:
Linux Set your LD_LIBRARY_PATH to:
${workspace_loc}/libosgvp/libjni-osgvp/target/target_cmake/lib:/home/your_username/.depman/lib
For windows XP your PATH must point to (pay attention to word bin):
${workspace_loc}/libosgvp/libjni-osgvp/target/target_cmake/bin:c:/documents
and settings/your_user/.depman/bin
This is mostly correct. However, for Windows, the CLASSPATH and PATH must use
; and not :
Throughout all of my attempts of setting the command window's CLASSPATH, and
PATH environment variables plus setting the eclipse internal LD_LIBRARY_PATH
and PATH variables, I naturally used ; in the command windows variables but not
within eclipse.
Once I used ; between the paths within the PATH environment variable in
eclipse, the application finally found all the needed dll's it was searching
for.
But, now I have a bigger problem. kernel32.dll on Windows XP. I've attached my
error log and here is what the error output is as produced while running from
within eclipse. The application crashes after producing this error:

I've done this under Windows.

Re: [osg-users] [ANN] OSG Virtual Planets, the core of gvSIG3D.
Another Note:
your batch file, run-Examples.bat
@echo off
SET PATH=binaries\win32;%PATH%
SET OSGVP_JARS=.
for /f delims= %%a in ('dir lib\ /s /b') do call :process %%a
echo OSGVP_JARS=%OSGVP_JARS%
java -cp %OSGVP_JARS% org.gvsig.ExamplesLauncher
:process
set OSGVP_JARS=%OSGVP_JARS%;%1
assumes that the directories:
binaries
binaries\win32
lib
all exist. Yet, after I ran ant, not ant vs8, none of those directories were
constructed. I even ran ant vs8 but received an error message that eclipse:vs8
did not exist. Or something like that. I can not remember now.

Re: [osg-users] [ANN] OSG Virtual Planets, the core of gvSIG3D.
Hi Jordi what you said does help but it also brings up another question: how do I run osgvp from Eclipse? I have compiled everything with ant. I have read the User's Manual, section 9.2.2, and it states how that one must import the osgvp projects into Eclipse. Do I recompile the projects in eclipse after I have imported them? What other environment variables must I set? How do I correctly set the CLASSPATH? You may notice, I have no instructions on how to run the examples from within eclipse or how to correctly set up my eclipse environment to do that. I do not know how to setup my command-line environment so that if there are any environment variables that must be set before starting eclipse, that I correctly set them and then run the examples.

Re: [osg-users] [ANN] OSG Virtual Planets, the core of gvSIG3D.
Hi Rafa Jordi, Rafa, something you said triggered an old memory of mine: I must run the vcvarsall.bat file to setup the correct environment for vs8 and for compiling from the command line. I only could guess that you opened the wrong Visual-Studio command line, so the environment is not correctly configured. So, I found vcvarsall.bat; I set up my cmd tool to run this batch file every time I start a cmd tool; and then I re-ran ant; EVERYTHING WORKED after that. :):) I have attached my installation guide for your review and use if you would like to have it. It is what I had to do to get osgvp to install and build under Windows XP 32-bit. As for using eclipse, I have not installed it yet for Windows. I would like to use NetBeans, though, for java development on windows and ubuntu. Have you ever used NetBeans to develop java applications that are based on osgvp? My next move is to start developing a simple java application that starts an osgvp window and displays a simple terrain file. Thank you for your support. I really appreciate it! :):) Allen -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=24507#24507 Attachments: http://forum.openscenegraph.org//files/osgvp_windows_xp_32bit_install_889.txt ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] [ANN] OSG Virtual Planets, the core of gvSIG3D.
HI Jordi Good to know that ubuntu 9.0.4 will work. I was able to upgrade to maven 2.0.10. I was using the version that comes wiht 9.0.4 ubuntu, which is maven 2.0.9. EVERYTHING COMPILED! Ye ha! :) :) :) So maven 2.0.10 was the final solution to the equation for getting osgvp to work for me, was well as moving my already installed version of osg, unsetting certain environment variables and using the correct java compiler. All very critical components. I have looked at the pdf users manual you suggested. It contains no detailed documentation on how to install osgvp for windows or any OS for that matter. So, I think a command line sequence guide will be extremely helpful. I am writing my own installation guide for ubuntu 9.0.4 and I wish to submit it to you for review. I am hoping for osgvp to become very important to my current and future development and having a step-by-step guide on how to install it for windows and linux is going to be extremely necessary. Thank you so much for yours and Rafa's help!!! I could not have done this without you! :) :) Do you have a step-by-step write up on how to install osgvp for Windows XP? If you do, would you please send it to me? Thank you.

Re: [osg-users] [ANN] OSG Virtual Planets, the core of gvSIG3D.
Hi Jordi Ok, I am on Windows XP 32-bit OS now and I need your help once again. CMake is finding my compiler, VS8 but unfortunately it is finding the 64-bit compiler. Is there a way to get CMake to use the 32-bit version of the microsoft VS 8 development environment? I believe I am supposed to be using the 32-bit compiler. From the user doc you spoke about, I installed ANT and used ant. I still got the exact same error message below. I wish I could wait for the binaries to be available but I must also have the source code as I will be developing against osgvp and I will need access to the composite viewer java interface that osgvp provides. It is critical that I get osgvp's java compositer viewer working the way I need for it to work in my appliation both under linux and windows XP.

Re: [osg-users] [ANN] OSG Virtual Planets, the core of gvSIG3D.
Hi Jordi I did not know that a specific version of maven was required for Ubuntu. I, myself, use Ubuntu 9.0.4 and I can not upgrade to 9.10 because my graphics card is not recognized by that version of Ubuntu, so if it is a requirement to use Ubuntu 9.10 to run osgvp, I can not use your product. Also, I am trying to get osgvp to run under Windows XP 32bit. Do you have a step by step installation guide for osgvp on Windows XP? I need osgvp running on Ubuntu 9.0.4 as well as Windows XP as I will be developing on Ubuntu and deploying a product on Windows XP and a current step by step guide to install osgvp on to XP would be greatly appreciated. I will check my maven version under ubuntu and let you know what version I am using. However, are you sure that the version of maven I am running is causing my latest error under ubuntu?

Re: [osg-users] [ANN] OSG Virtual Planets, the core of gvSIG3D.
Hi Rafa, I understand your previous message. Honestly, I did not think that using the default java as installed through the synaptic manager was different from Sun Java. So, here is what I have done: 1. I have installed Sun Java version 6 2. I have setup my environment variables 3. I downloaded the source code again and started with a fresh install 4. I have removed the OLD .m2 directory 5. I am using the CMakeList.txt file you directed me to use 6. I am running as my local account and not root 7. I have included my entire output from my latest attempt. 8. I have tried to use the binaries and the run-Examples.sh brings up a window but when I click on any example, the application crashes 9. I downloaded and I am using the osgvp-2.2.0-SNAPSHOT-src source code 10. I am using the command: mvn install -Dmaven.test.skip=true Here are my environment vars: #env | grep OSG OSG_INCLUDE=/usr/local/include OSG_BIN=/usr/local/bin OSGGTKMM_INCLUDE=/usr/local/include/osgGtkmm-0.1 OSG_FILE_PATH=/media/numenor/OpenSceneGraph-2.8.1/OpenSceneGraph-Data-2.6.0 OSG_LIB=/usr/local/lib OSG_DIR=/usr/local/include:/usr/local/bin:/usr/local/lib OSGGTKMM_LIB_ROOT=/usr/local/lib OSG_ROOT=/usr/local OSGGTKMM_ROOT=/usr/local/include #env | grep JAVA JAVA_HOME=/usr/lib/jvm/java-6-sun JAVA_INCLUDE_PATH2=/usr/lib/jvm/java-6-sun/include/linux/ JAVA_INCLUDE_PATH=/usr/lib/jvm/java-6-sun/include/ #env | grep GDAL GDAL_LIBRARY=/usr/lib GDAL_INCLUDE_DIR=/usr/include/gdal GDAL_BIN=/usr/bin GDAL_DIR=/usr/include/gdal:/usr/bin:/usr/lib ## jogl info ( Loaded onto system via synatic manager ) libjogl-java-doc libjogl-java libjogl-jni ERROR: ( and this error is repeated for several different modules ) Configuring done [exec] CMake Warning at CMakeModules/OSGVPMacros.cmake:9 (ADD_LIBRARY): [exec] Cannot generate a safe runtime search path for target osgvpcore because [exec] there is a cycle in the constraint graph: [exec] dir 0 is [/home/allen/.depman/lib] [exec] dir 1 must precede it due to runtime library [libOpenThreads.so.11] [exec] dir 1 is [/usr/local/lib] [exec] dir 0 must precede it due to runtime library [libosg.so.55] [exec] Some of these libraries may not be found correctly.

But I am truly at a loss as to how to get your package to compile under Ubuntu 9.0.4 as these new errors are completely different from what I was receiving. I have made sure that osg has GDAL support; I believe I am using the correct jogl; and I do have GDAL installed. I am very happy that you are using Ubuntu. Could you possibly tell me what else I am over looking? I believe I have followed every thing that you have stated thus far. I have double checked the README.txt file as well as our notes here and I do not see anything that I am doing wrong.

Re: [osg-users] [ANN] OSG Virtual Planets, the core of gvSIG3D.
Hi Rafa Ok, setting the JAVA_HOME env variable did help. What must JAVA_INCLUDE_PATH and JAVA_INCLUDE_PATH2 be set to? I do have a jdk installed on ubuntu and the consistent errors I keep getting are with the JAVA_HOME and JAVA_INCLUDE variables. Setting the JAVA_HOME environment variable got rid of one CMake/Mvn error. Thx for the note on the composite viewer. Once I get this up and running, I'll see how I can use the composite viewer in osgvp and see if it works for me.

Re: [osg-users] [ANN] OSG Virtual Planets, the core of gvSIG3D.
Rafa, My latest attempt synopsis: 1. set the Java home variable 2. set the java include path variable 3. set the java include path2 variable and then I re-ran mvn clean mvn install -Dmaven.test.skip I still had a crash. maven would not work. THen I decided to run maven as root: sudo mvn install -Dmaven.test.skip and all of the sudden, maven started to work. I am now seeing a lot of files being downloaded and I have NEVER seen that before while attempting to run mvn. I did not know I had to run mvn with root priviledges. I also googled the JAVA_INCLUDE_PATH and figured out how to set those 2 variables correctly. So... now I am waiting for maven to finish. However, I do notice I get checksum failed for a few packages. I hope this does not cause a problem.

Re: [osg-users] [ANN] OSG Virtual Planets, the core of gvSIG3D.
Ok, well, I keep getting the same errors from maven or cmake and I really don't understand what is wrong. No matter what I do, the JAVA_INCLUDE_PATH and JAVA_INCLUDE_PATH2 are not recognized as being set but they are. I have included my output from maven and I really do not understand it. Why do you think the java include paths are not being recognized but I have set them and they are correct. The Java home variable has been set correctly, too.

Re: [osg-users] OSG Viewer and JOGL
Hi Rafa. I just found this article in the OSG Forums and am very interested in osgvp. Is there a tutorial on osgvp? And if so, would you tell me where? I've downloaded the snapshot for all platforms and am compiling the projet with maven. I just need a good tutorial as to how to use this product. I really really like the fact that it can possibly load my dted and cib terrain data on the fly w/o having to pre-generate this data specifically for osg. Thanks so much Rafa. Rafa Gaitan wrote: Hi Kevin, Well osgvp is quite large currently, but you can take a look to libosgvp-viewer library and take only what you need. If you feel comfortable with maven, you can try to compile it and use only libosgvp-viewer and libosgvp-core library. Currently trunk compiles against osg 2.8.2, but you can use a trick to compile it against osg trunk just setting the OSG_DIR env var pointing to the osg compiled sdk. This two libraries allow to create the context using jogl with the first method that Robert commented. You can take libosgvp-viewer and use it and even with a few mods I think you can use without all the libosgvp-core wrappers. The JNI code is inside osgvp/libosgvp/libjni-osgvp/, so you can take a look there and use the code you need. Good luck with your project, Rafa. On Wed, Jan 6, 2010 at 7:05 PM, Robert Osfield wrote: Hi Kevin, I know nothing about Java/JNI so can't comment on the specifics, but in general I'd suggest that you could use the osgViewer::GraphicsWindowEmbedded functionality that enables the standard osgViewer::Viewer/CompositeViewer to handle a single window without doing any of its own windows/wgl/glx calls - leaving these entirely up to the calling application. For examples of this in action have a look at the osgviewerSDL and osgviewerGLUT examples that come as part of the OSG's example set. Such a embedded window is fine for most apps that just require a single window and single threading of the viewer, but isn't a scalable as the native OSG windowing implementations. Another route might be to try and get the underlying window handle of a window created by java and then pass this to osgViewer::GraphicsWindowWin32/X11 using it's support for inheriting windows and adding it's own graphics context. This approach is the most flexible w.r.t the OSG as it enables the OSG to handle threading and multiple graphics contexts directly. Robert.

We are interesting in adding a considerable GUI interface to the application and we would prefer to use JAVA to implement the GUI. So basically I am trying to find a way, probably using JOGL, to create the GUI and graphics window on the JAVA side and perform all of the drawing on the C++/OSG side. I think I should be able to create a glContext on the JAVA size, with JOGL, and when making a call to C++ with JNI have access to the same context as long as it is done within the same thread. Unfortunately, I have not figured out how to assign the JAVA created glContex, retrieved with a call to wglGetCurrentContext, to the OSG Viewer/Camera. I know that osgvp has created a JAVA/JOGL/JNI interface to OSG but it looks like a lot of effort went into creating the JNI interface and making calls into OSG. I would really like to reduce the JNI to little more than init, display, keyboard, and mouse functions. Any help is appreciated.

[osg-users] Rotation about Arbitrary Axis: Please help...
Hi all, I'm having fun learning about rotation about an arbitrary axis and it's not working as I expected it to at all. I am using the code from the Trackball manipulator to construct a local origin at a point that is actually @ the edge of my earth sphere. It goes like this: osg::Vec3d Up(0,0,1); osg::Vec3d focalPt(x,y,z); osg::Vec3d x_axis = Up ^ focalPt; // up cross focal should give x-axis? osg::Vec3d y_axis = x_axis ^ focalPt;// should be y-axis?? osg::Vec3d z_axis = x_axis ^ y_axis; I can construct the x-axis w/o a prob and I can rotate about it - though it LOOKS LIKE A PITCH that I am actually performing and not a ROLL. This behavior is very strange to me. :( To actually perform the rotate, I do the following: osg::Quat q(AngleOfRotation, x_axis); osg::Matrixd mtxd = osg::Matrixd::rotate(q) * OriginalPositionMatrixd; The mtxd computed is the correct rotation about the x-axis but, again, it appears to be a PITCH instead of a ROLL. OriginalPositionMatrixd is computed as follows: osg::Vec3d ov3d = s_paxNode-getPosition(); osg::Quat q= s_paxNode-getAttitude(); osg::Matrixd mtxdR; mtxdR.makeRotate(q); osg::Matrixd mtxdT; mtxdT.makeTranslate(ov3d); osg::Matrixd OriginalPositionMatrixd = mtxdR * mtxdT; //order matters MY PROBLEM: when I attempt to rotate about y-axis or z-axis which I think are local to the focalPt, the rotation is totally wrong. It rotates in an completely unexpected way. Would someone please explain to me how to properly construct a local origin at my focal point so that I can rotate my model, which is at that point, around the local x,y and z axes? I am on the surface of the Earth, too, and I want to actually rotate my model about it's z-axis so as to change the azimuth the model is facing. Note: whether the axes are normalized or not seems to make no difference though I think that that should make a difference. ... Thank you very much!

Re: [osg-users] TerrainManipulator Questions
Hi, Thanks guys for all the help. I finally figured out how to setup a Rotation Matrix and I am now using the setByMatrix of the TerrainManipulator correctly to position the camera. It's awesome! But I have found a curious thing, it appears that the same method in Trackball Manipulator is not correct. Every time I've called it, it never updates the camera's position and I do not think it's calculating the position/orientation information correctly, either. but thanks for the help! I really appreciate it. ...

[osg-users] TrackballManipulator possible bug; definite issue
Hi,
I don't know if anyone has delt w/ this problem yet, but it appears that
TrackballManipulator has a bug in it in the methods, setByMatrix() and
computePosition().
I could be wrong, as I'm a novice in OSG, but I have observed the following:
setByMatrix()
1. does not work for me as every time I call it, the camera's position
orientation are not altered or updated
2. the code appears to be incorrect compared to other manipulator examples
which work.
from NodeTrackerManipulator:
void NodeTrackerManipulator::setByMatrix(const osg::Matrixd matrix)
{
osg::Vec3d eye,center,up;
matrix.getLookAt(eye,center,up,_distance);
computePosition(eye,center,up);
}
this code works. But from TrackballManipulator:
void TrackballManipulator::setByMatrix(const osg::Matrixd matrix)
{
_center = osg::Vec3(0.0f,0.0f,-_distance)*matrix;
_rotation = matrix.getRotate();
}
This code does NOT work.
as for computePosition()
1. in TrackballManipulator, it appears to be using COLUMN MAJOR matrices but
OSG is row major.
2. as compared to NodeTracker and Terrain manipulators, the method for
computing the position/orientation is consistent. However, in the Trackball it
is performed using, I believe, an invalid way to fill a matrix with
rotation/orientation information.
Has anyone else encountered this?
...
Thank you!
Cheers,
Allen

Re: [osg-users] TerrainManipulator Questions
Hi JP, thanks for the idea. I'd forgotten that about aspect of the Terrain Manipulator. Hum, so I've got to get the Terrain Manipulator (TM) to actually intersect w/ the terrain node I really want instead of the sphere surrounding the terrain. As for what I passed, I sent in the address of the terrain node and not the entire scene or the sphere node's address. And I noticed that the _node variable should contain the address I sent to setNode and it so happens that that variable is used often in the call to intersect(). This is curious. I will have to verify more completely that the address I sent in is what I think it is. O, do you know when setByMatrix is called from w/in the rendering pipeline? I truly don't entirely understand what OSG operations occur during the viewer.frame() sequence. ... Thank you!!!

Re: [osg-users] TerrainManipulator Questions
Hi JP,
thanks so much! I found a partial solution and I'm trying to understand why
it works. hahahaha
but here's what I found:
1. I have 3 nodes in my scene @ startup: terrain, light, and a sphere wrapping
my terrain. All built/added to root node in that order.
2. the intersect routine found 3 points of intersection; once I choose the 3rd
point, the manipulator allowed me to go-down-to the terrain!!! Which is what
I originally wanted.
O, I also had to duplicate the TerrainManipulator class, rename it and use it
as my base class of CSceneMatrixManipulator because I had to over-ride the
intersect() method to get it to do what I wanted it to do. intersect() is not
virtual in the base TerrainManipulator and every time I tried to alter it in a
subclass of TM, my subclasse's method was never called.
Now I just have to figure out how to access the node from the intersect
point, get it's name verify I'm working with the terrain node and all will be
great. :D
Here's my code for giggles.
**
bool CSceneMatrixManipulator::intersect(const osg::Vec3d start,
const osg::Vec3d end, osg::Vec3d intersection) const
{
std::coutMy Intersect\n;
osg::ref_ptrosgUtil::LineSegmentIntersector lsi = new
osgUtil::LineSegmentIntersector(start,end);
osgUtil::IntersectionVisitor iv(lsi.get());
iv.setTraversalMask(_intersectTraversalMask);
_node-accept(iv);
if (lsi-containsIntersections())
{
std::multiset
osgUtil::LineSegmentIntersector::LineSegmentIntersector::Intersection
::iterator itr=lsi-getIntersections().begin();
std::cout # Intersects:= lsi-getIntersections().size()
std::endl;
// intersection =
lsi-getIntersections().begin()-getWorldIntersectPoint(); // ori 102909 gas
// When used w/ a SKY DOME/Sphere taht acts as a sky dome, need to skip
// that vertex point and goto the terrain beneath it, which should be
the
// next intersection point/vertex. gas 102909
//
itr++;
if (itr!=lsi-getIntersections().end())
{
std::cout got 2nd intersect point\n;
intersection = itr-getWorldIntersectPoint();
}
else
intersection =
lsi-getIntersections().begin()-getWorldIntersectPoint();
return true;
}
return false;
} // intersect
**
...
Thanks again JP!
Cheers,
Allen

[osg-users] TerrainManipulator Questions
Hi, I'm trying to use the TerrainManipulator class and I am scratching my head. Problem: I use a patch of terrain w/in a simple program and the terrainmanipulator works great. In another example of mine: I then add a sky-dome by simply putting a sphere around the terrain and painted the sphere with a pic of the sky. I then re-ran my application and the terrain manipulator basically stops zooming in once I get really close to the sphere which wraps my terrain. At that point, I can NEVER get close to the terrain again, ever! Does anyone know why? I even tried using the method, setNode(), w/in the terrain manipulator and that did not change things at all for me. ... Thank you!

Hi, I will explain what I didnt understand in the code.Does calling scene-accept(updateVisitor); everyframe will automatically call the updatecallbacks and update the scene.Because here no viewer.updateTraversal() or sceneview-update() methods are not called to update the scene.
