Re: [osg-users] [3rdparty] Distributed rendering (was: RE: Cloud node kit)
Selam Muhammed; This http://www.ub.uit.no/munin/bitstream/handle/10037/1065/thesis.pdf;jsessionid=C0E24ED29579BADBBA942B95B8C93B1D?sequence=1master thesis may help you to solve your problem about how OpenSceneGraph supports distributed rendering. Regards. Ümit Uzun 2011/4/10 Muhammed Kalkan kalkanik...@gmail.com Hi, Sorry if subject changed in previous topic. In my humble knowledge of distributed rendering, i think scene graph must have some kind of mechanism to sync frames to be rendered in each cluster (rendering machine). As your post states , a socket communication can transmit the sync messages. However what i wanted to know is how we build the structure for OSG to make sense of it. In short how and which part of OSG do we pass these sync messages to obtain distributed rendering. Thank you!

Re: [osg-users] SetImage problem
Selam Osman, Did you try void osg::Image::setOrigin ( Originhttp://www.openscenegraph.org/documentation/OpenSceneGraphReferenceDocs/a00305.html#3eb3fb7f290c3b5ef6122b76d5fe6c69 *origin* ) [inline]function before convert TopLeft image to BottomLeft? May be you won't need any flipping operation before setImage funtion. And another hint, are you sure your captured image's depth is IPL_DEPTH_8U from OpenCV. You have set GL_UNSIGNED_BYTE to image type but may be your type could be IPL_DEPTH_16U or IPL_DEPTH_32U. Hope this helps. Regards. Ümit Uzun 2010/5/29 Osman Hancer enderenderenderen...@hotmail.com Hi, I want to convert an OpenCV IplImage to an OSG image. For this, I first fliped image from top-left to bottom-left by cvConvertImage(cvImg , cvImg, CV_CVTIMG_FLIP); then converted BGR to RGB color format by cvCvtColor( cvImg, cvImg, CV_BGR2RGB ); then I used setImage to do the actual conversion. osgImg-setImage(cvImg-width,cvImg-height, 3, GL_RGB, GL_RGB, GL_UNSIGNED_BYTE,(BYTE*)(cvImg-imageData),osg::Image::AllocationMode::NO_DELETE ,1); The result is not what I expected.

Seems it uses some optimization algorithm, kinda Depth peeling or something else. But I would like to get true transparency with simple tringle sorting.

Hi Nick,
However, I started the osgwidgetinput example and for some reason it is
not getting my input from the keyboard.
This is the same problem I noticed in other osgWidget classes lately.
Someone changed the signature of virtual methods in the EventInterface class
(which Widget inherits and thus, all other Widgets too) adding a const, but
didn't change the signature of methods that are supposed to overload those
virtual methods in derived classes. So for example, EventInterface defines:
virtual bool keyDown (int, int, const WindowManager*) { return false; }
virtual bool keyUp (int, int, const WindowManager*) { return false; }
but Input defines:
virtual bool keyUp (int, int, WindowManager*);
virtual bool keyDown (int, int, WindowManager*);
So there is no compile error, but the base class methods are called
instead of the derived class methods because their argument lists don't
match.
Here's the change for Input. It would be nice to go across all osgWidget
classes and fix this if you have the time. I already did it for Frame a week
or so ago, and this fixes Input, but there are bound to be more.
Hope this helps,
J-S

Hi Simon, Thanks for your advices, but I need to apply unordered rotation. And I don't want to think about rotation apply order.

[osg-users] Rotation 2 DOF node with 2 Different Matrix.
Hi All, I have a problem about rotating one MatrixTransform node with 2 different Matrix which one of responsible for rotation on X by osg::X_AXIS and one of responsible for rotatin by osg::Y_AXIS. I have done some rotation to MT node but after this operations I am waiting to get Identity matrix for MT which has Identity matrix in initial state. Some psudo codes; - // Initial states osg::MatrixTransform* MT; MT-setMatrix( osg::Matrix::identity() ); osg::Matrix ang1 = osg::Matrix::identity(); osg::Matrix ang2 = osg::Matrix::identity(); // Updates done with this codes ang1.preMult(osg::Matrix::rotate(osg::Quat(osg::DegreesToRadians(10.0f), osg::X_AXIS))); ang2.preMult(osg::Matrix::rotate(osg::Quat(osg::DegreesToRadians(10.0f), osg::Y_AXIS))); MT-setMatrix(ang2 * ang1); - if I rotate my MT by above code; model rotated on Y by localCoordinate axis and rotated on X fixedCoordinate axis. But I wanted to rotate on X local coordınate axis too.

But this code has lack too. After apply positive and negative way rotation I am waiting to get IdentityMatrix but after all rotation operation my MT-getMatrix() give me different from IdentityMatrix. I think I should use inverse matrix instead of negative direction rotated matrix to rotate -X or -Y direction. Could it solve my problem or not? By these 2 rotation operations my main goal is that; I want to rotate MT by X and Y local coordinate system. And after all rotations I can get initial state of MT. I mean I apply to many rotation transformation to my unique node and after all dual(for X and -X or for y and -Y with unordered queue) operation I want to get first initial matrix for my MT node. I know this is not hard operations, but I am unstable about choosing which one is right way. I appreciate any comments. Regards.

Hi Maxim; If you have time could you look at http://www.delta3d.org/article.php?story=20050720155458456topic=tutorials Resource Creation section to conform some rules to make much general conversion.

Re: [osg-users] Simple water effects
Hi Dominic; As you know there is too much resource on the net.

Re: [osg-users] Simple water effects
Hi Dominic, thanks for the interesting links, but the habib tuturials are all for direct x, right? And I don't see how I have to integrate with OSG (sorry for the stupid questions, but I'm a beginer at all...). Yes right. But he has good understanding to achieve kind of water surface. You can grasp the understanding and make yourself in GLSL. I can't find the real worldz examples on the net, do you have the source? Grab the GLSL book and look at Real Worldz section. There is not comprehensive source code and example, there is only information to how you can create water surface. If you are very beginner, you need to learn water mathematic(which habib's talked about enough in his site) and implementation by GLSL. I think you have already known this is not trivial operation.

Re: [osg-users] GLSL tricks about texturing.
Hi All, May be my former question not much understandable. I want to try express my problem again. I have a 3D model which is created by Blender. As you guess, model has to many texture on it. After I export my model in standard model type(3ds or what else), I want to make per pixel shading on my model. My question do I have to define all my texture in fragment shader as uniform sampler2D xxx and bind this uniform in my related osg::Program one by one to shade my model per pixel lightening? How can I reach related pixel's texture value in fragment shader if I doesn't use sampler2D? For example, now I can access to related pixel's texture value by; uniform sampler2D diffuseTexture; vec4 texture = texture2D(diffuseTexture,gl_TexCoord[0].st); But if I doesn't define my sampler2D to related texture how can I access? Thanks in advance. Regards. Ümit Uzun 2009/10/30 Ümit Uzun umituzu...@gmail.com Hi Folks, I am using PerPixel lighting on my some model which has created with Blender. My model has lots of textures on it. And my question is, do I have to send all textures in uniform variable to shader? That makes all think to complex, doesn't that? I have try to send only one texture to shader and saw that it can texture all of texture on my model instead of only send one. Then I realize that declared uniform sampler2 sampleTexture definition doesn't hold the related texture file. It only hold texture unit, I mean 0,1 or 7. My question is what is the standart shadering operation when we have canned model? Should we send texture's to shader or what else? And sending texture is meaningless, because if we have ive or another texture integrated model what should we do this time? We haven't related texture separately? This time what should we send? Thanks in advance. Regards. Ümit Uzun ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] GLSL tricks about texturing.
Hi JS, Thanks so much for your detailed explanations. I get your thinking. I have known same think but I didn't sure very well. My last question is, I have declared; uniform sampler2D diffuseTexture; in my fragment shader, although I didn't bind it to osg::Uniform in my main application, I can sample my texture from my shader in Unit 0. Do you think it is weird or not? You have said that; I only need to bind my uniform sampler2d variable in my application to set to related stateset. I didn't set to stateset too, but I get the unit 0 texture value from shader and can see my model textured. Thanks again. Regards, Ümit Uzun 2009/10/30 Jean-Sébastien Guay jean-sebastien.g...@cm-labs.com Hi Ümit, How can I reach related pixel's texture value in fragment shader if I doesn't use sampler2D? I don't understand why you would *not* use sampler2D? You always need a sampler to sample the texture in a shader. But if I doesn't define my sampler2D to related texture how can I access? You just need to create a uniform and set it correctly. Then you'll have a sampler. See my other message.

Re: [osg-users] TangentSpaceGenerator usage...
Hi Alessandro,
Try my bumpmapping sample from

Hope this helps.
Ümit Uzun
2009/10/30 alessandro terenzi a.tere...@gmail.com
I'm trying to use the TangentSpaceGenerator in order to apply a bump
mapping shader, but I cannot manage it to work properly. Having looked also
at the osgFX::BumpMapping effect, I used the visitor defined in BumpMapping
in order to find all the geodes and apply TangentSpaceGenerator on them, but
if I save the model to disk just before and after the generation has been
applied, I notice that in the .osg the arrays supposed to contain normals,
tangents and binormals are empty...here is the only part that is different
among the two .osg:
VertexAttribBinding 1 PER_VERTEX
VertexAttribNormalize 1 FALSE
VertexAttribArray 1 Vec4Array 0
{
}
VertexAttribBinding 6 PER_VERTEX
VertexAttribNormalize 6 FALSE
VertexAttribArray 6 Vec4Array 0
{
}
VertexAttribBinding 7 PER_VERTEX
VertexAttribNormalize 7 FALSE
VertexAttribArray 7 Vec4Array 0
{
}
6 is supposed to be the TU of the tangent, 7 is for binormal attributes and
1 for the normal map textures. The model have textures coordinates set for
TU 0 that is associated to the diffuse map.
Maybe I'm missing some steps to setup properly everything...
Thanks in advance. Kind regards.

Hi Nemo, I ask DisplaySetting configuration because of some system hardware not support more multisampling and sometimes viewer open up in full screen. Your suspect about stateHandler does not cause this problem. But you should check your m_hWnd. It should be right handler for your CView. Because base parameters to create rendering window boundaries are got from m_hWnd. Regards. Good Luck.

Ni Nemo, There is osgViewerMFC example in the source, and firstly you should get the rendering way by scratching the codes. And then you can implement your with same way. There is not much example on MFC, so your only chance is osgViewerMFC I think. Regards.

Re: [osg-users] problem in setPivotPoint of PAT for .3DS file
Hi Gopal,
Sometimes canned models pivotpoint set to undesired position which not
suitable your desired pivotpoint position. So to solve this problem you have
two chance, you can open your model by 3D model programs and after you
configure pivotpoint you export it again and use new model or set your
desired pivot position to your PAT node by setPivotPoint. Its usage so
simple. You choose your desired global point to make pivot your PAT node.
For example;
osg::Node* createRoom(osg::Node* loadedModel) // From osgLight example
{
// default scale for this model.
osg::BoundingSphere bs(osg::Vec3(0.0f,0.0f,0.0f),1.0f);
osg::Group* root = new osg::Group;
if (loadedModel)
{
const osg::BoundingSphere loaded_bs = loadedModel-getBound();
osg::PositionAttitudeTransform* pat = new
osg::PositionAttitudeTransform();
pat-setPivotPoint(loaded_bs.center());
As you can see from attached code we get the models boundingSphere's center
and make it pivotPoint. After this initialization your model will be rotated
around this point by setAttitude command.
You can look at osgLight, osgLauncher and osgLogo too.
HTH.

Hi,
I am using OSG-2.8.0
i have read a .3DS file with a certain origin.
now i am trying to rotate the object in the file about a point other than
its origin in that file .
for that i have used PAT.
i have tried to use setPivotPoint but could not understand its working
can any body suggest the way to use it . if possible with an
example...
Thank you!

Re: [osg-users] problem in camera rotation
Hi Akilan;
Matrix multiplaction is not commutative. If you change the order of matrix
as a result the accumulated matrix will behave different as you anticipated.
So order of matrix multiplexing is Scale, Rotate and lastly Translate. So in
multiplexting operation order of them as follows;
AccumulatedMatrix = TranslateMatrix * RotateMatrix * ScaleMatrix;
So I suggest you to use one MatrixTransform because you can do all operation
in one MatrixTransform too. And try rotMT-setMatrix(tmatrix * rmatrix); and
delete transMT. Use single MatrixTransform.
HTH.

Hi Filip; This is impossible because all example uses generated library, includes and dll's on your own platform so you have to compile OSG Core library too.

Re: [osg-users] Compress image
Hi Ufuk;
Compress word doesn't define your expected operation very well. This
operation's name is Mipmapping. You should generate automatic mipmapping for
your texture in runtime and the you can choose any resolution you have
created to use your program.

is there any function that compress image in osg?
for example i have an 256x256 image and i want to compress it to 128x128 or
64x64...
i checked for osg::Image::scaleImage() but it did not change the
resolution.. maybe i did something wrong?
Here is the code:
///
void simUtil::SimImageUtils::scaleAndSaveImage( osg::Image* image, float
scaleFactor, const std::string filename )
{
osg::ref_ptrosg::Image cImage = new osg::Image(*image);
cImage-scaleImage(image-s() * scaleFactor, image-t() * scaleFactor,
image-r() * scaleFactor);
osgDB::writeImageFile(*image, filename);

Re: [osg-users] Compress image
Hi Ufuk;
If you want to create mippaped images on your disk instead of
programmaticaly. I suggest you to use GIMP to mipmap(rescale each different
resolution image separately) and when you need you can call related
resolution image :)
Is this your expected or you want to create one image which has all
resoluted images in it? If you want kind of this operation you can use dds
format. But I don't know osg does support reading mipmapped dds format.

Hi Ümit,yes, i need mipmapping but i want to store these mipmapped
textures on disk. i dont want so many calculations on rendering...
so i wanted to store these images on disk.
do you know a way to do this or i should write a code?

Re: [osg-users] Reference count catcher?
Hi Ufuk;
As I know, If you create a new object with using ref_ptr, object's default
ref_ptr should be initialized to 1. And after you have attached it to your
scene, ref_ptr count gets 2. And after you delete your geometry from your
scene graph ref count gets 1 again. And then this ref_ptr object will be
deleted automatically when intelligent ref_ptr decided to it is unneccessary
some times later. And then it will be deleted automaticly. Be cool.
ref_ptr's target is counting pointer usage and finding unneccesary pointers.

Hi Ufuk,
I don't know whether there already is a solution, but I'd suggest you to:
1. Add virtual qualifier before osg::Referenced::ref method:
inline virtual void ref() const;
2. Rebuild OSG
3. override this method in your custom Geometry class
class MyGeometry : public osg::Geometry
{
public:
inline virtual void ref() const
{
osg::Geometry::ref();
}
};
4. Place breakpoint to that method and see callers.
You can do the same for unref method as well. I haven't tested this
but seems like to give you some hints.

Re: [osg-users] [forum] Help to use osgViewer in MFC
Hi Nguyen; OpenSceneGraph has multithreaded structure on drawing, culling and some kind of operation and singleThreaded structure on update traversal. So if you want to add or remove some nodes from your scene graph you should do this operation any updating operation sector. For example you can create one update callback and you can do these operation in it. Or you have to stop viewer renderer and then you do your add-remove operation and then start threading again. So application doesn't crash. But stopping and starting renderer thread is not best solution. This is my humble opinion. Regards.

myCameraMatrix = cameraRotation * cameraTrans;
osg::Matrixd i = myCameraMatrix.inverse(myCameraMatrix);

switch(ea.getKey())
{
case osgGA::GUIEventAdapter::KEY_Down:

}
}

Re: [osg-users] Transformations
Hi Paul;
So in OSG first of all I try to do it with a osg::Switch but seems that
this node accumulate the transformations... is that right?
What do you mean about osg::Switch. It's not specific feaute on accumulating
trasformation for osg::Switch as I know. It actual target is switching node
while rendering scene graph.
What type gridOrientation is?
Be careful while multiplying the matricies because precedence is important
for kind of these operations : result = rotation * translation;
Regards.

2009/7/17 Pau Moreno Font tekka...@gmail.com
Hi,
I'm trying to change my OGL code to OSG but I'm having really problems with
the transformations... I have 174 data files that each contains a cloud of
points, a vector3 with the translartion, and the matrix of rotation of each
cloud. So in OGL, i just do:
{
LoadFile( x++) //Loads a diferent file in each
iteration
glPushMatrix();
glTranslate( x , y , z )
glMultMatrixf( rotation );
glBegin( GL_POINTS )
glEnd();
glPopMatrix();
}
So in OSG first of all I try to do it with a osg::Switch but seems that
this node accumulate the transformations... is that right?? So what I
finally do is to attach a diferent node in each iteration and detach the
previous one. But the real problem is that OSG is not doing the same as OGL.
I do this for each node:
{
osg::Matrixf rotation;
osg::Matrixf translation;
osg::Matrixf result;
rotation.set( gridOrientation.get( 0 , 0 ) , gridOrientation.get( 0 , 1
) , gridOrientation.get( 0 , 2 ) , 0.0,
gridOrientation.get( 1 , 0 ) , gridOrientation.get( 1
, 1 ) , gridOrientation.get( 1 , 2 ) , 0.0,
gridOrientation.get( 2 , 0 ) , gridOrientation.get( 2
, 1 ) , gridOrientation.get( 2 , 2 ) , 0.0,
0.0f , 0.0f , 0.0f , 1.0f );
translation.setTrans( x , y , z );
result = rotation * translation;
osg::MatrixTransform *transformation = new osg::MatrixTransform();
transformation-addChild( gNode );
transformation-setMatrix( result );
}
rotationOGL.makeRotate( osg::DegreesToRadians(90.0) , osg::Vec3d( 0.0 , 1.0
, 0.0 ));
transformationOGL-setMatrix(rotationOGL);
transformationOGL-addChild(m_root);
m_vViewer.setSceneData( transformationOGL );
m_root-addChild( transformation );
.
What I'm doing wrong? I've tried a lot of combinations of creating rotation
, translation, result, but no one is the correct!! I think I'm doing
something wrong I cannot apreciate.
Thanks!!

Re: [osg-users] what is the thread difference between MFC and console?
Hi Forest; We have same problem and I find that threading isn't actual problem. real one is rendering on specified HWND. And frame rate always gets down while enlarging the HWND size contrary if you collapse the HWND size you can see easily that frame rate gets upper degree than wide one. I suspect that low frame rate is caused by rendering on specified HWND. If you really need to render on MFC control(i.e PictureBox) you should narrow you HWND control size to get high frame rate.

Re: [osg-users] MatrixTransform accumulation
Hi Yang, Translation operation isn't same as rotation operation. While one object is rotating in every transformation node by traversing the scene graph from parent to child, every node can effect the current rotation state to the target child node. Distinctly in translation operation every node try to translate target child node to specified coordinate point which is every PAT node instantiate it with osg::Vec3(10.0f,10.0f,0.0f). Actually every PAT nodes effect the child node to locate it osg::Vec3(10.0f,10.0f,0.0f) but only last one is validate on this operation. Becase PAT4 is the last node before the child node. So you can't hope to accumulate traslation value as rotation value. I hope that I did't tell you wrong explanations.

Re: [osg-users] Any suggestion about OSG-ODE integration and collision detection.
Hi Sukeder, Thanks Sukender. I have decided to achieve Collision Detection in Physics Engine as you suggested.

Regards. 2009/6/25 Sukender suky0...@free.fr Hi Ümit, About collisions, I agree you whould do it in the physics engine. (BTW, does PhysX *require* a NVidia card? I guess no) And if you wish to have something that doesn't hide OSG, and that is much simpler than Delta3D, then you may look at what I did in PVLE ( http://pvle.sourceforge.net ). For the moment, I must admit ODE is a bit hidden in PVLE, but I'm currently modifying it so it also shows ODE as it does for OSG. There are many other implementations that can bind physics and OSG (see osgPhysics too... but it's not finished yet), but if you wish something simple, then PVLE may suit your needs.

[osg-users] I can't load Released OSG library in Debug Mode.
Hi All, Until now, I have been using VS2003 in all project. But we have upgraded to VS2008. I don't know why can't load released OSG in Debug mode or vice versa. It throws and std::badalloc exception while using reading some model or images by osgDB's static functions(readNode, readImageFile etc...) But same code works when working same mode. VS2008 don't let us to use this interchangeability anymore or should I set some parameters?

Re: [osg-users] I can't load Released OSG library in Debug Mode.
Thanks Vincent and JS; It is interesting no-no which is seen to me odd :) It always restrict us while using created dll project which uses osg. So I have to create my own dll project in two version (debug and release) for compiling new project which uses this dll in it for possibility of beeing different compilation mode.

VS2008 don't let us to use this interchangeability anymore or should I set some parameters? You mean you're trying to link an app compiled in debug with an OSG lib compiled in release, or vice versa? Yeah, that's a big no-no, and it's been discussed often on this list. You need to match the debug/release across your whole project, at least since VC++ 2005. Otherwise the standard library used is different and makes different assumptions about how to allocate memory and other things. This is true for any library that is coded in C++. If the dependency contains only C code, you can use only the release version of that lib with both release and debug applications if you want. The OSG dependencies packages contain both release and debug dependencies, and CMake will choose the right one when compiling OSG. You just need to make sure you do the same thing in your own apps/projects - when compiling your project in release, link to osg.lib/osgDB.lib/... and when compiling it in debug, link to osgd.lib/osgDBd.lib/... Hope this helps, J-S -- __ Jean-Sebastien Guayjean-sebastien.g...@cm-labs.com http://www.cm-labs.com/ http://whitestar02.webhop.org/ ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org -- Ümit Uzun ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] Any suggestion about OSG-ODE integration and collision detection.
Hi Sergey; I have known about Delta3D. It uses ODE too, but I am in contradiction about using pure OSG and ODE or using Delta3D game engine. To use Delta3D I have to spend some to get the structure and wrappers all other library. But with using pure OSG and ODE I can adopt so quickly. Anyway I thanks for your suggestion, and I will try to understand Delta3D's integration way.

Re: [osg-users] Any suggestion about OSG-ODE integration and collision detection.
Hi Micheal; Thanks for your polite offer to helping me:) I have looked Bullet and Nvidia PhysX. I can't choose PhysX because I want to run my PhysX engine ATI. I think it's not support. Or do you think it can be modified to send the physics calculation to CPU instead of GPU on PhysX. I had tried to grasp the Bullet but it seems much complicated then ODE, so I choosed ODE. Yes as you said, I have to handle collision detection and create contact with physics dynamics if I choose another collision library instead of own one. So this is big problem, so the real solution seems to use main library of ODE. If you have any suggestion, I appreciate with glad :) Regards and Thanks. 2009/6/18 Michael Bosse' metis...@gmail.com One more thing, if you do your collision detection in OSG, you will need to handle the physical response yourself. The physics engine is already set up to handle that correctly. For starters, i'd just stick with physics.

Should I declare specific Environment Variable to help cmake for finding right fftss include directory and library? And Do we have to OpenThreads library in debug mode? I have a OSG distiribution in only release mode. Regards. 2009/6/16 Kim C Bale k.b...@hull.ac.uk Hi Martin, This problem arises with two particular effects, the glare and the underwater dof which require special treatment of the alpha component in the framebuffer. You can disable those using: enableUnderwaterDOF(false) enableGlare(false) Then you need to disable the default scene shader with this: setUseDefaultSceneShader(false) In the OceanScene class. If you remove the default shader you'll also lose the underwater light scattering and fogging calculations on models below the surface. Trying to offer lots of out-of-the-box shader effects whilst also accommodating the fixed pipeline is a tricky problem and this area needs a little work, but that should work for you.

Please set them or make sure they are set and tested correctly in the CMake files: FFTSS_INCLUDE_DIR When you run CMake it should let you set these manually if they’re not found automatically. You will need to explicitly specify the path to the include directory and also the fftss.lib file (this is what I do when I run CMake) When you run the example application the fftss.dll will need to be in the same directory as the exe or by adding the directory it’s in to your PATH environment variable (if you’re in windows) OPENTHREADS_LIBRARY_DEBUG linked by target osgOcean in directory C:/Projects/Ocean/osgOcean-Source/src/osgOcean I think if you just point it to the release mode version of OpenThreads it will let you build the project.

Regards. 2009/6/16 Kim C Bale k.b...@hull.ac.uk Hi Martin, This problem arises with two particular effects, the glare and the underwater dof which require special treatment of the alpha component in the framebuffer. You can disable those using: enableUnderwaterDOF(false) enableGlare(false) Then you need to disable the default scene shader with this: setUseDefaultSceneShader(false) In the OceanScene class. If you remove the default shader you'll also lose the underwater light scattering and fogging calculations on models below the surface. Trying to offer lots of out-of-the-box shader effects whilst also accommodating the fixed pipeline is a tricky problem and this area needs a little work, but that should work for you.

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] 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. In Projects and Solutions VC++ Directories, select Library files from the Show Directories For menu, then add this directory to the list: C:\Program Files\Microsoft SDKs\Windows\v6.1\Lib Regards. 2009/6/9 crope...@sohu.com Hello All, Is there something wrong in OsgDB::Registry::LoadLibrary(std::string libname) when i load the .curl plugin in debug , it is shown that the .curl plugin con't be found.However,it works well in release mode. when i open osgDb_curld.dll in depends_22, msvcr80d.dll con't be found.The ThirdParty depencies in svn dotn't have osgDb_curld.dll file in its child folder Bin,I move msvcm80d.dll msvcp80d.dll msvcr80d.dll Microsoft..manifeVC80.DebugCRTst files to thirdPary/Bin ,however it doesn't work! my osg version is osg 2.6,ide Vs2005!

In which case you would want to use the glsl function cross(vec3,vec3)

You should have a read about the geometry math being used here. Blindy

ok, i got the world position with:
Code:

vec3 worldPos = ToWorldMatrix * gl_Vertex;
now i need to check which side of the plane the worldPos is.
I googled and found some code for this but its not for glsl, ive came up
with this but i get errors.
the code is:
Code:
vec3 n;
float d;
n = (pos1 -pos0) ^ (pos2 - pos1);
d = -n * pos0;
inside = 1.0;
if (dot(n, gl_Position) + w)
{
inside = 0.0;
}
the errors i get are:

so i tried
Code:
vec3 n;
float w;
int p0 = (pos1 -pos0);
int p1 = (pos2 - pos1);
n = p0 ^ p1;
w = -n * pos0;
inside = 1.0;
if (dot(n, worldPos) + w)
{
inside = 0.0;
}
but it alway returns inside = 0.0;
any ideas?

Re: [osg-users] osg2cpp sample needs a tweak?
Hi Robert;
Yes I know we need endline sign on every line break. Actually we put endline
sign by
foutvariableString\shaderSource.substr(startOfLine,endOfLine-startOfLine)
*\\n\*std::endl;
So there is one \n sign in
shaderSource.substr(startOfLine,endOfLine-startOfLine) substring. Could you
look at the attached samples and converted type of vertex shader. Do you see
shadow_vert.cpp files distorted format?
If I am wrong, so sorry for inconvenience.

Hi Umit,
The \n is used to make sure that the warnings you get back from the
OpenGL driver map to distrinct line numbers, without this all the
lines would be treated as a whole program ecoded in a single line.

My Graphic Card : ATI Radeon Mobility HD 2300 256 MB OS : Windows XP Best Regards. 2009/5/6 Jean-Sébastien Guay jean-sebastien.g...@cm-labs.com Hi David, I would suggest that an all GPU FFT would just be one in a selection of possible ocean surface techniques. An architecture that supports many such techniques would be a good goal for this kind of project ! I totally agree. I'll be looking into how feasible this is, not just for offloading surface generation to the GPU, but in general for allowing selecting the surface generation technique from a list of possible techniques with different tradeoffs. As soon as there's a non-GPL alternative integrated instead of FFTW, I can start working on that.

Re: [osg-users] osgOcean release
Hi Kim; Thanks for your help but I think when you attach the water vertex and fragment shadr you had made a mistake and you attached two of them in vertex there is no fragment shader. Now I have achieved to GLSL 1.2 and OpenGL 2.1 but it still not enough. I am trying to update to 3.0. Now previous Error gone away but now application send fragment shader not supported as you can see from command screen; glLinkProgram FAILED Program infolog: Fragment shader(s) failed to link, vertex shader(s) linked. Fragment Shader not supported by HW Warning: detected OpenGL error 'invalid operation' after RenderBin::draw(,) RenderStage::drawInner(,) FBO status= 0x8cd5 Could you attach water.f please? :) Best regards and Thanks. 2009/5/7 Kim C Bale k.b...@hull.ac.uk David,J-S,Art, Yes this the direction I envisaged for it, I attempted to pull out some common variables into an OceanTechnique base class, but as you can see in the code, that all went a bit pear shaped as I didn't really know how the others were going to be implemented.. The CUDA implementation is certainly something to look at but should be seen as an alternative rather than a main route as it excludes people with lesser graphics cards and, dare I say, it the ATI contingent. There's a nice video here if people are interested. http://www.youtube.com/watch?v=K1I4kts5mqc K. -Original Message- From: osg-users-boun...@lists.openscenegraph.org on behalf of Jean-Sébastien Guay Sent: Wed 06/05/2009 20:07 To: OpenSceneGraph Users Subject: Re: [osg-users] osgOcean release Hi David, I would suggest that an all GPU FFT would just be one in a selection of possible ocean surface techniques.

Re: [osg-users] osgOcean release
Hi Jean; As you said I know there will not be any difference for OSG in OpenGL 3.0 but I have tried to upgrade to make my GLSL support to 1.3 or upper(1.4). Anyway at last I have already realized that my 2.5 years old GPU doesn't support to OpenGL 3.0 in any drivers. So as you suggest to Kim about controlling OpenGL and GLSL version by preprocessor definitions should be implemented to osgOcean before making this nodekit part of OSG built in nodekit. Best Regards. 2009/5/7 Jean-Sébastien Guay jean-sebastien.g...@cm-labs.com Hi Umit, Now I have achieved to GLSL 1.2 and OpenGL 2.1 but it still not enough. I am trying to update to 3.0. Whether or not your driver supports OpenGL 3.0 won't make any difference, OSG does not use OpenGL 3.0 at all (you need to explicitly create an OpenGL 3.0 context in order to use it, and OSG doesn't yet). It's strange that ATI's drivers do not support GLSL 1.3 though - the latest versions of their drivers should, as it's been a while since it's been released now. Anyways, I see that Kim's modified shaders work for you by not using GLSL 1.3 features, but I still think it's strange... :-) J-S -- __ Jean-Sebastien Guayjean-sebastien.g...@cm-labs.com http://www.cm-labs.com/ http://whitestar02.webhop.org/ ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org -- Ümit Uzun ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
