Re: [osg-users] Transparency on geode and shared stateSet
Hi, I'm the original poster, and the problem I had is that I cannot use a material, because it will modify the state set, that is common for a lot of other geodes... But thanks for the answers, maybe i'll have some kind of revelation with your help. Can't it be interesting for OSG to have a setTransparency() method on a node ? using material or something else, but working in each case... Thanks. Regards, Vincent. 2009/6/9 Jason Daly jd...@ist.ucf.edu Andrew Cunningham wrote: Adjusting the material color alpha will work for some geometries but I have other geometries where each vertex has a BIND_PER_VERTEX color ( think of a contour plot of a value), so I would still need to adjust the alpha of each vertex color. Actually you don't (unless you need a different alpha for each vertex). Normally, the material's settings will override the color array values. However, if you set the Material's color mode to some value other than NONE, the material color for that element (AMBIENT, DIFFUSE, AMBIENT_AND_DIFFUSE, SPECULAR, or EMISSION) will be replaced by the vertex color. Unless you doing something fancy, you can typically set the color mode to AMBIENT_AND_DIFFUSE, which lets you make use of your vertex colors, but vary the alpha as you need to. Look in the red book, or the glColorMaterial man page for more info. --J ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] ArgumentParser issues on Windows?
Hi Butler;
It is well known problem :) I think your OSG system only compiled in release
mode and you are trying to build this example in debug mode, so program
throw bad_alloc exception. Try to build your example same build type as your
OSG system. If it is released mode you build your example in released mode
or vice versa.
Regards.
2009/6/9 Butler, Lee Mr CIV USA USAMC lee.but...@us.army.mil
The following code works on Linux/Mac but not Windows. Is there
something I should realize about ArgumentParser and ApplicationUsage?
Maybe it's some Windows/VS2008 thing I've missed?
-
#include osg/ArgumentParser
#include string
int main(int argc, char * argv[])
{
std::string name(Fred);
osg::ArgumentParser arguments(argc, argv);
osg::ApplicationUsage *au;
au = arguments.getApplicationUsage();
// the next two lines cause runtime errors on Window
au-setApplicationName(name);
std::string cmdLineName = arguments.getApplicationName();
return 0;
}
-
The au-setApplicationName(name) line gives the error:
Unhandled exception at 0x76bc42eb foo.exe MicrosoftC++ exception:
std::bad_alloc at memory location 0x0018f37c..
commenting that line out results in the next line producing:
arguments.getApplicationName() causes Unhandled Exception at
0xHexAddress in foo.exe 0xC005: Access violation reading location
0xccc0.
This is setup as a Windows Console App in VS2008.
I can set a breakpoint on the first line and see that argv[0] and argc
are set reasonably.
Stepping forward I note that the constructor for ApplicationUsage
doesn't initialize _applicationName. Visual Studio debugger notes Bad
Ptr on au-_applicationName before the call to:
au-setApplicationName(name)
Odd since _applicationName is declared:
std::string _applicationName;

Re: [osg-users] [forum] Ray tracing
Hi Roland, When you say the program is jerking I presume you mean that the intersection traversals are taking long enough that they are breaking frame. The solution for faster intersection traversals is to use osg::KdTree's attached the the geometry leaves. You can hint to the OSG to build KdTree's automatically for you on loaded new models be doing: osgDB::Registry::instance()-setBuildKdTreesHint(osgDB::ReaderWriter::Options::BUILD_KDTREES); Before you load your models. You can also build the KdTree's by hand. The other approach would be to run the intersection traversal multi-threaded. Robert.

Re: [osg-users] ImageStream with different sized images
Hi Jason, Changing the size of an image will require creation of a new texture object, something that is not ideal as it could cause a stall in rendering. Would it be possible to use a different texture for the first image? Would it be possible to resize the image to the size of the movie? Another thing you could try is to set the size of the texture to 640x480 prior to the first frame that it's rendered. Robert.

For example, displaying a Buffering image when data is being downloaded from Internet. I'm using the setImage() function to alter the data of the underlying image, and the issue I'm running into is that it resizes the image frames the size of the first frame I send to the ImageStream. For example, if I set a 256x256 image that says Loading... while the movie data is being download from the Internet, once the frames start coming in at say 640x480, they are all resized to 256x256 b/c that was the initial size of the image. I've looked at the osgimagesequence example and it does the same thing, all the images are resized to size of the first image.

Re: [osg-users] building 2.8.1 with dcmtk
Hi John, The CMakeCache.txt will contain both ITK and DCMTK if they are present on your system. The dicom plugin will build against DCMTK if all the required component are available. DCMTK_FOUND will be set to TRUE if it's found all the components. Looking at your email it looks like it can't find the headers, so have a look into this. With the ITK causing build problems it does sound like it's broken in someway w.r.t the compiler set you are using. Unless you need it you might as well just uninstall it. Robert.

Re: [osg-users] Transparency on geode and shared stateSet
You could implement the full fixed function pipeline (the parts you need) in a custom shader with the addition of manually controlling transparency based on a uniform. Actually, a fragment shader may be all you need... which is probably a lot easier than a fixed function pixel shader. I've been tempted to do this before myself as fading in/out a model for LOD or otherwise is a real pain. -Paul Vincent Bourdier wrote: Hi Robert, I am aware of the mess this is to implement... but I need it, and I cannot create my scene graph appropriately because it it generated by some exporter (osgExp) so I have to work with graphs I cannot control.

Re: [osg-users] Transparency on geode and shared stateSet
Hi Paul, Shader can be a solution, but a shader is a part of the StateSet, and i'm looking at the best way to avoid using them. But i'll keep that in mind. Thanks. Regards, Vincent. 2009/6/9 Paul Speed psp...@progeeks.com You could implement the full fixed function pipeline (the parts you need) in a custom shader with the addition of manually controlling transparency based on a uniform. Actually, a fragment shader may be all you need... which is probably a lot easier than a fixed function pixel shader. I've been tempted to do this before myself as fading in/out a model for LOD or otherwise is a real pain. -Paul Vincent Bourdier wrote: Hi Robert, I am aware of the mess this is to implement... but I need it, and I cannot create my scene graph appropriately because it it generated by some exporter (osgExp) so I have to work with graphs I cannot control.

Trying to embed low state management like transparency in nodes would be an utter mess to implement and to maintain for developers and end users.

Re: [osg-users] Segmentation Faults while file accessing (models) because of multiple threads?
Hi Jonas, When running on a multi-pipe machine I would recommend used osgViewer to do the multi-thread and multi-window work, it's designed to do this and will provide the best performance. Equalizer will be more suited for cluster work. Now I don't use Equaliizer, let alone use it the way you are using, and even then it's not something I would recommend, but if you really must use it this way then you will have to do the debugging work, if wish assistance from the community you need to provide far more information about the nature of the crash, a single line of code is practically meaningless.

Hi robert I do agree with you, that for this topology, the multithreaded osgviewer would be the better approach.

Re: [osg-users] [forum] Ray tracing
Hello All: Also, just a question. Is this a custom graph or are you using the SceneGraph with static terrain objects,... etc. I had a custom scene graph and intersections were killing me but when I realized that the Intersect visitor sets a ACTIVE_CHILDREN for the traversal I used this knowledge to only intersect what I needed. For instance i only did leaves that were not culled with respect to the culling type used when doing terrain intersection and if you have custom objects you can do the same for that as well. Once I made sure that only active children were being addressed this helped considerably. Take care Garrett On Jun 9, 2009, at 3:48 AM, Robert Osfield wrote: Hi Roland, When you say the program is jerking I presume you mean that the intersection traversals are taking long enough that they are breaking frame. The solution for faster intersection traversals is to use osg::KdTree's attached the the geometry leaves. You can hint to the OSG to build KdTree's automatically for you on loaded new models be doing: osgDB::Registry::instance()- setBuildKdTreesHint(osgDB::ReaderWriter::Options::BUILD_KDTREES); Before you load your models. You can also build the KdTree's by hand. The other approach would be to run the intersection traversal multi- threaded. Robert.

Re: [osg-users] Load PlugIn Library in OsgDB::Registry
Hi Croperli; Look at the http://www.skew-matrix.com/bb/viewtopic.php?f=8t=3 Troubleshooting the Build Did osgdb_curl.dll fail to link? OSG creates several libraries during a build. One of the libraries, osgdb_curl.dll, has a special dependency on Windows. During the OSG build, if this library fails to link, and the link error indicates that wldap32.lib can’t be found, you’ll need to manually configure Visual Studio’s library search path and possibly install the missing library. Note that the compile works fine, or fails, depending on the compiler you are using. Currently, this is only an issue for some editions of VS8. All VS9 installations appear to include this library. Adding wldap32.dll is more art than science. If the file is already installed on your system, you can find it by doing a file search in C:\Program Files. Then, you simply add the directory to the library search path as described below. If you don’t have wldap32.dll already installed, download and install MS Windows SDK for MS Server 2008http://msdn.microsoft.com/en-us/windows/bb980924.aspx(do a web search to find it). After this is installed, enter the VS IDE options.

Doing something like the following on unit 0 works great in that case, but I also want to add in another scaling factor that will scale the alpha value of the texture from 0 to 1 to essentially act as a slider for the opacity.

From my understanding of texenvcombine, I can either use a constant color or SRC_ALPHA as an operand, but not a combination of both. It sounds like you need three parameters combined (2 texture colors and a user-defined parameter), so your only hope is the INTERPOLATE mode for the alpha values (INTERPOLATE is the only combiner operation that takes three parameters). Try this: tec-setSource0_RGB(osg::TexEnvCombine::TEXTURE0); tec-setSource1_RGB(osg::TexEnvCombine::TEXTURE1); tec-setCombine_RGB(osg::TexEnvCombine::MODULATE); tec-setConstantColor(osg::Vec4(1.0, 1.0, 1.0, userDefinedAlpha)); tec-setSource0_Alpha(osg::TexEnvCombine::TEXTURE0); tec-setSource1_Alpha(osg::TexEnvCombine::TEXTURE1); tec-setSource2_Alpha(osg::TexEnvCombine::CONSTANT); tec-setCombine_Alpha(osg::TexEnvCombine::INTERPOLATE); I just made this up, so I have no idea if it will work or not. It might not be the only possibility, either, but it's all I can think of right now. --J ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] Camera Placement Question: Geocentric reference
Hi all, I'm having difficulty moving a camera to a specific point to look at in a geocentric coordinate reference frame. I've got a geocentric point that I want my camera to look at and the point is in x,y,z form where x,y,z are in meters. I do not understand how to translate and rotate my camera to this point. Is there a setByViewMatrix method in OSG any more? Some examples refer to it and I can't find it. If not, is there an equivalent? Or is there an easier way all the way around? Thanks for the help!

Re: [osg-users] Multidisplay FBO performance
Hi Bryan, I have similar setup. 8800 GTS Windows XP 32 bit driver version. Drivers 185.85. Default (undefined USE_FBO) osgviewer cow.osg on two 1280x1024 screens runs at 600 hz.

Re: [osg-users] Moving Line of sight
Hi Roland, You'll need to recompute the position of the ray in world coordinates by taking the ray in local coords to the node and multiplying by the accumulated world matrix of the node in question. You can get the world matrices from any node by doing node-getWorldMatices(). Please note this might be back 0, 1 or many Matrices, depending upon the particular set up of your scene graph i.e. how many parents with transforms your node has. Robert.

Jason Daly wrote: Andrew Cunningham wrote: Adjusting the material color alpha will work for some geometries but I have other geometries where each vertex has a BIND_PER_VERTEX color ( think of a contour plot of a value), so I would still need to adjust the alpha of each vertex color. Actually you don't (unless you need a different alpha for each vertex). Normally, the material's settings will override the color array values. However, if you set the Material's color mode to some value other than NONE, the material color for that element (AMBIENT, DIFFUSE, AMBIENT_AND_DIFFUSE, SPECULAR, or EMISSION) will be replaced by the vertex color. Unless you doing something fancy, you can typically set the color mode to AMBIENT_AND_DIFFUSE, which lets you make use of your vertex colors, but vary the alpha as you need to.

Re: [osg-users] 2.8.1 Image::readPixels and packing.
Call it what you like (bug, not optimal behavior, I don't care) but I would
expect that in a code snippet
image-setPacking(4)
image-readPixels(,,,)
That the readPixels call would respect the the packing that you set in previous
line.However Image::readPixels resets the packing to 1
That is a problem for me as I require a packing of 4.
A code inspection the shows that this is the case.
..
voidallocateImage (int s, int t, int r, GLenum pixelFormat, GLenum type,
int packing=1)
..
void Image::readPixels(int x,int y,int width,int height,
GLenum format,GLenum type)
{
allocateImage(width,height,1,format,type); -- 'missing' default
parameter packing=1 causes 'allocateImage' to set packing to 1
glPixelStorei(GL_PACK_ALIGNMENT,_packing);
glReadPixels(x,y,width,height,format,type,_data);
}
One solution would be to add a 'packing' parameter to readPixels.

Re: [osg-users] master/slave camera question
So... Let me see if I understand this... Assuming I pass no args to the app when I run it, the osgdistortion createDistortionSubgraph first creates a camera which will render the scene to a texture attached to an FBO before the main camera renders the scene. Then the hud camera is created to render the quad textured with the texture created by the previous camera? So I have two slave cameras in addition to the main camera? How would I render scene to a depth texture? Do I create a depth texture and attach it to the first camera? Assuming that I want to use the texture created by the first camera as an input to frag shader program, would I need to add a third camera which I would add the shader as is done in the osgshaders example?

error:
//system.cpp, Line 305,

{
datasetMap.erase(itr-second);

}
Evidently, the iterator was used incorrectly. So i changed it:
void eraseFrom(System::DatasetMap datasetMap)
{
for(TimeIteratorMap::iterator itr = _timeIteratorMap.begin();
itr != _timeIteratorMap.end();)
{
itr = datasetMap.erase(itr-second);
}
}
Then it works. My version is r973. Hope to correct it in later version.
