Re: [osg-users] reflect vector ?
Hi Julien, Thanks for your answer, but I am looking for precompute function in osg, not in glsl. Someting like osg::Vec3 R = osgUtil::reflect(osg::Vec3(...), N), same for matrix.

Re: [osg-users] reflect vector ?
Hi, Sure, and I knew the math before you helped me, but I was just wondering if something was already existing in osg. Computing reflection (and refraction) vectors/matrces are pretty usefull now. I was wondering if osg had a reflect function into utils libs or elsewhere, but now I guess it does not.

Re: [osg-users] dynamic cube map
Hi thank you Nick I found your discussion about osgprerenderCubeMap I did a search on dynamic cube map but I didn't find anything. Thank you!

Re: [osg-users] dynamic cube map
Hi Nick,
ok I did have a look at the osgPrerenderCubeMap code and at you thread about
mixing a static 2D texture and a dynamic cube map into a shader. btw your
version with
Code:
{
osg::Uniform* u = new osg::Uniform(osg::Uniform::SAMPLER_CUBE,cubeMapUnit);
u-set(unit);
node-getOrCreateStateSet()-addUniform( u );
}
works well for me
I tried this sample with my own camera (Y up) and that works well too.
I want to use this sample in a more general case (dynamic reflection on water
for example) . I tried to use the bottom plane as the reflector but the
reflection is now awfull... Did you work on it ? Can you confirm ?
Thank you
Sebastien

Re: [osg-users] dynamic cube map
Hi Nick,
Well the changes are minors. I just wanted to change de reflector from the
sphere to the bottom plane (or box).
here is my reflector function, I changed the sphere to a box geode, ie the
bottom plane/box.
Code:
osg::NodePathcreateReflector()
{
osg::PositionAttitudeTransform* pat = new
osg::PositionAttitudeTransform;
pat-setPosition(osg::Vec3(0.0f,0.0f,0.0f));
pat-setAttitude(osg::Quat(osg::inDegrees(0.0f),osg::Vec3(0.0f,0.0f,1.0f)));
osg::Geode* geode_1 = new osg::Geode;
osg::ShapeDrawable* shape = new osg::ShapeDrawable(new
osg::Box(osg::Vec3(0.0f, 0.0f, -2.0f), 10, 10.f, 0.1));
shape-setColor(osg::Vec4(0.5f, 0.5f, 0.7f, 1.0f));
geode_1-addDrawable(shape);
//osg::Geode* node = new osg::Geode;
//const float radius = 0.8f;
//osg::ref_ptrosg::TessellationHints hints = new
osg::TessellationHints;
//hints-setDetailRatio(2.0f);
//osg::ShapeDrawable* shape = new osg::ShapeDrawable(new
osg::Sphere(osg::Vec3(0.0f, 0.0f, 0.0f), radius * 1.5f), hints.get());
//shape-setColor(osg::Vec4(0.8f, 0.8f, 0.8f, 1.0f));
//node-addDrawable(shape);
pat-addChild(geode_1);
osg::NodePath nodeList;
nodeList.push_back(pat);
nodeList.push_back(geode_1);
return nodeList;
}
And I have commented the code corresponding to the same bottom plane in the
_create_scene() function.
Code:
//shape = new osg::ShapeDrawable(new osg::Box(osg::Vec3(0.0f, 0.0f, -2.0f), 10,
10.f, 0.1), hints.get());
//shape-setColor(osg::Vec4(0.5f, 0.5f, 0.7f, 1.0f));
//geode_1-addDrawable(shape.get());

[osg-users] dynamic cube map
Hi, I am trying to make a dynamic cube with osg. The idea is to render into a cube map the +X, -X, +Y, -Y, +Z and -Z view from the camera view point at each frame. Then the cube map is textured on a reflector surface (a plane) within a shader. I would like to see other objects (sphere, cube) reflecting in my plane as it was a mirror. I managed to make the cube map and to texture it on my plane but the reflection is not correct, and I need some ideas to correct my app. Ok, so I build a cubemap texture with osg, then I create 6 camera nodes. theses cameras are looking at +X, -X, +Y, -Y, +Z and -Z directions and are attached with a callback to the main camera position. I use this command to attach the cube map texture for each camera : Code: camera-attach(osg::Camera::COLOR_BUFFER, m_textureEnvMap, 0, i); Then I use this fragment shader to map the cube map on the plane : Code: // world space eye vector vec3 E = normalize(posWorld.xyz - cameraPosWorld); // plane world vector (hadcoding!) vec3 N = vec3(0,1,0); vec3 coord = reflect(E, N); vec3 reflectColor = textureCube(cubeMap, vec3(coord.x, coord.y, coord.z)).rgb; posWorld is the current fragment world position (posWorld = modelMatWorld * gl_Vertex); cameraPosWorld is the camera world position (passed with uniform). I would like to have some advice and ideas about my program. Did anyone already try to make dynamic cube ? What did I miss ? Thank you!

Another question I did have a look at your code and I do not understant what is the cube texture unit for ? Does it contains the 6 face cube dynamic textures, but why did you code it if you do not use it ? Thank you!

[osg-users] [osgPPU] osgPPU cube map sample
Hi, I would like to know what is the aim of the cube map sample. When I launch this sample, I've got some satellite objects that are moving arround a bigger sphere, this sphere seems to be mapped with an envmap made of 6 colors (red, green etc...). But the envmap is not dynamic (ie the sattelite objects do not reflect in the bigger sphere). Is it normal behavior ? Thank you!

Re: [osg-users] [osgPPU] osgPPU cube map sample
Hi, Well I had a look in the code shader, you set gl_fragColor with a color depending on the face index osgppu_CubeMapFace. The corresponding update code is in void UnitInOut::init() method. That's why the bigger sphere holds colors. But the samplerCube input is unused in this sample, why ? Is this texture holds the reflection of the satellite objects ?

[osg-users] dependancies with Visual2005 SP2
Hi, I am running on Visual 2008 SP2 with osg 2.8.2 I have just downloaded osg binaries for visual 2005 SP1 and I have this message when I launch my app in debug mode : The application failed to initialized properly (0xc0150002). Click on OK to terminate the application. Well I guess that does not work because I use Visual2005 SP2 et not SP1. After few research on this forum, I have read that my solution is to compile all osg library (and plugins) myself, so I did, and that works. My question is now about the dependancies. When I want to load a mesh (.ive file) I need zlib1d.dll, so I have donwloaded this library from VC2005 SP1 dependancies. But I have the could find plugin to read objects from file ...ive message. The plugin was compiled and is present in osgPlugins-2.8.2/osgdb_ived.dll directory. I am pretty sure this error comes from an incompatibility with zlib1d.dll because the osg binary dependancies are also available on VC2005 SP1, and not on VC2005 SP2. What do you think ? and If I am right, how to get the VC2005 SP2 dependancies ? Does any one had already this problem ?

Re: [osg-users] [osgPPU] no results with osgPPU
Hi Arts and have a happy new year
Ok so I have decided to make a simple stand alone application to test what you
said : create a new camera as a child of the main camera, the child camera will
be the FBO camera for the PPU processor
here is a part of my code :
Code:
void buildPPUScene(osg::Group* root, osg::Camera* camera)
{
setupFBOCamera(camera);
// create PPU
osgPPU::Processor* postProcessor = new osgPPU::Processor();
root-addChild(postProcessor);
// initialize the post process
postProcessor-setCamera(camera);
postProcessor-setName(Processor);
postProcessor-dirtyUnitSubgraph();
//
osgPPU::UnitBypass* bypass = new osgPPU::UnitBypass();
bypass-setName(HDRBypass);
postProcessor-addChild(bypass);
// just a resample example
osgPPU::UnitInResampleOut* resample = new osgPPU::UnitInResampleOut();
resample-setName(Resample);
resample-setInputTextureIndexForViewportReference(-1); // need this
here to get viewport from camera
resample-setFactorX(0.1);
resample-setFactorY(0.1);
bypass-addChild(resample);
//
osgPPU::UnitOut* ppuout = new osgPPU::UnitOut();
ppuout-setName(PipelineResult);
ppuout-setInputTextureIndexForViewportReference(-1); // need this here
to get viewport from camera
resample-addChild(ppuout);
}
int _tmain(int argc, _TCHAR* argv[])
{
osgViewer::Viewer viewer;
osg::Group* root = new osg::Group;
// get main camera
osg::Camera* camera = viewer.getCamera();
// read node
osg::Node* node = osgDB::readNodeFile(cow.osg);
// create child camera
osg::Camera* ppuCamera = new osg::Camera;
// add new camera as main camera child
camera-addChild(ppuCamera);
// init viewports
initCameraViewport(camera, 400, 400);
initCameraViewport(ppuCamera, 400, 400);
// build PPU resample scene
buildPPUScene(root, ppuCamera);
// add readed node as new camera child
ppuCamera-addChild(node);
viewer.setSceneData(root);
viewer.realize();
return viewer.run();
}
The setupFBOCamera function is the same as your setupCamera function present in
your osgppu_viewer example : it creates renderTexture, attaches it to the
camera in parameter and sets the camera to render into a FBO.
If I do not create the ppuCamera, it works well, I have my resample cow (in
this case the cow node is a child of the root).
But with the new ppuCamera, I have a black screen, as if no nodes are rendered;
that is strange because the cow node is a child of the new ppu camera, and it
should be rendered... no ?
So what do I make wrong ?
Thank you!
Cheers,
Sebastien

So I guess osgPPU is not disable. I did what you suggest, and I have a black screen, like there was no root. I have one question about your graph, did you mean that the main camera node has 2 children : the osgPPU processor and the custom FBO camera with your graph ? I have set the FBO camera with RELATIVE_RF transform and I didnt set the view and projection matrices. I guess the view matrix will be update by its parent and osgPPU will set the projection matrix with a 2 projection. Am I right ? Thank you!

Re: [osg-users] [osgPPU] no results with osgPPU
Hi Art, With the graph you propose, I have the back screen, I have checked and the scene graph is correct, I didn't forget to attach any nodes, so I do not understand. By modifying directly the main camera,I did it too, and I have the scene with no osgPPU (no resambled scene) like I explained on my 1st post. I have checked too in the debut mode, and the camera has still the FRAME_BUFFER_OBJECT mode on each frame. So I do not understand either. I see in debug mode that the main camera holds pre and post render callback, do you think these functions may interfer with osgPPU ? Well I really appreciate your help but I begin to think it is impossible to guess what the host application is doing without the code or any documentations.

Re: [osg-users] [osgPPU] no results with osgPPU
Hi, I tried with FRAME_BUFFER_OBJECT but I have the same result (ie no results ^^) But I think I have to explain my program context. In fact, I am developping a plugin for a closed application (I do not have the source of this application); within this plugin I have an access to the root scene graph, and I can get the camera with the static graphic context (getAllRegisteredGraphicsContexts) If I add my code to my own application, it works well. But if I add this code inside the closed application plugin, I do not have any results, as if osgPPU was disabled. Do you have any ideas of this behavior ? Maybe the closed application is resetting the camera each frame ? maybe a camera render callback disable osgPPU ? I really do not know, I do not have much experience with osgPPU and I need some ideas ...

Re: [osg-users] multiple pixel shaders for one program ?
Hi robert
thx for your answer
Ok I tried what you said, but I still have a pb.
I made a shader common.frag with a basic fog function
Code:
uniform vec3 fogColor;
uniform float fogDensity;
vec3 fog(in vec3 color)
{
const float LOG2 = 1.442695;
float z = gl_FragCoord.z / gl_FragCoord.w;
float fogFactor = exp2(-fogDensity * fogDensity * z * z * LOG2);
fogFactor = clamp(fogFactor, 0.0, 1.0);
return mix(fogColor, color, fogFactor);
}
And I did a main.frag with the main function
Code:
void main(void)
{
vec3 color = vec3(1,1,1);
color = fog(color);
gl_FragColor = vec4(color, 1);
}
then I load thoses shaders into one program as fragment shader
Code:
osg::Program* program = new osg::Program;
osg::Shader* shader = new osg::Shader(osg::Shader::FRAGMENT);
shader-loadShaderSourceFromFile(common.frag);
program-addShader(shader);
osg::Shader* shader1 = new osg::Shader(osg::Shader::FRAGMENT);
shader1-loadShaderSourceFromFile(main.frag);
program-addShader(shader1)
But when OSG compile my shader, it fails because fog is not known in the main
function.
Any ideas ? If I find the solution I will post...
thanks a lot

Hi Bryan, ok thx for your answer (even if I do not understand the 1st part of your message?) I did some research on the forum before posting, but maybe it wasn't enought. Thank you!

[osg-users] memory leak in osg 2.8.2 ?
Hi,
I take an osg example (I tried with the osgTeapot example project), then I add
the command
Code:
viewer.run();
_CrtDumpMemoryLeaks();
return 0;
at the end of the main function. (it dumps all the memory blocks in the debug
heap when a memory leak has occurred)
I launch it in debug mode, then I stop the application (ESC key) and I have
many memory leaks in my output debug window.

Re: [osg-users] [3rdparty] change ocean height
Hi JS ok I have updated osgOcean from the trunk and tried the new setOceanSurfaceHeight function. It is working well. Except that I have no node reflections in the water ? Did you try it ? In my 1st pic you can see the ocean and a cow at altitude 0, the reflection is great. [Image: http://img43.imageshack.us/img43/8820/water1h.jpg ] But when I add a (0,0,100) transform node for the cow and I use setOceanSurfaceHeight(100), I have no more reflections and a strange artifact at the horizon, see pic2 [Image: http://img25.imageshack.us/img25/9372/water2r.jpg ] Do you confirm this ?

Re: [osg-users] [osgPPU] resize osgPPU
Hi,
no you are right, nothing is wrong, but I was just thinking the new viewport
will automatically set the new camera aspect ratio
I did it and that works good now
here is my code
Code:
osg::ref_ptrosg::Viewport vp = new osg::Viewport(0, 0, width, height);
double fovy;
double aspect;
double znear;
double zfar;
camera-getProjectionMatrixAsPerspective(fovy, aspect, znear, zfar);
for(unsigned int i = 0; i m_ppuUnitList.size(); i++)
{
m_ppuUnitList[i]-setViewport(vp.get());
// m_ppuUnitList[i]-dirty();
}
camera-setProjectionMatrixAsPerspective(fovy, width / (double)height, znear,
zfar);
Thank you!

Re: [osg-users] FBO OpenGL Error with new nVidia Driver
Hi Robert Well, if I have asked something to this forum, this is because I have already investigated and I have found no solutions by myself. I just wanted to know if someone else has accountered this problem and if a solution has been found - I think a forum is for sharing problems and solutions - but if I am the only one to have this opengl memory overflow problem, so I must be the only one to use nvidia card and pre rendering pass with osg :|. By the way, the application is very simple because it is the osgPrerender example, and, as I said, the opengl memory overflow happens when a pre rendering pass is done into a fbo. I have a pretty good nvidia graphic card with the last driver (190.38, august 2009). I cannot try other hardware and if a solution is to downgrade drivers, I won't do that... Well, if one day I find a solution I will share Sebastien -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=17362#17362 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] FBO OpenGL Error with new nVidia Driver
Hi, Like Kim also said, I think the error is more likely in the driver than in OSG. Upgrading to OSG 2.8.2 won't hurt though :) I don't use Windows, but I've seen some utility to help you get rid of NVidia driver cruft on you machine before you install a new driver. I think experimenting with other driver versions is your best option Yes I think it is due to GeForce 8 series drivers, but I would prefer not to to downgrade my drivers.

[osg-users] multi render pass with different materials
Hi, Here is my problem, I use 2 passes to render a frame. On the 1st pass, I render the whole scenegraph into a texture with a material A on a node N. On the 2nd pass, I render the whole scene graph again and I use the texture from the 1st pass into a shader to render same node N with a material B. As you can see, the node N must have a material A on the 1st pass and another material B on the 2nd pass; and I do not know how to do this. All the rendering to texture and multiple pass rendering is done, but I do not know how to use a material A for my node N for the 1st pass, then to use a material B for the same node N on the 2nd pass. One first and ulgy solution may be to duplicate the scenegraph, and to assign a material A on my node N on the 1st copy of the scenegraph and to assign a material B on my node N on the 2nd copy of the scenegraph. But it is really ugly... Another better solution is - I think - to use a switch node. this switch node may be have 2 children, the 1st child may hold the material A and the 2nd child may hold the material B. These 2 children may have my node N as a child. But I don't know how to activate the 1st swith's child on the 1st pass and the 2nd switch's child for the 2nd pass. Does anyone of you have any ideas ? I think I may have to use render callback then to activate the correct switch's child for the correct pass, but I do not know OSG well and I don't know which callbacl to use and how to get the render pass number.

when I use this code,

It is like a bad pointer has been passed in

Hi The geode pointer is valid And I have the same problem with visual 2008... the assert fails while deallocating the matrix list (on the last bracket) the assert is this one : windows has triggered a breakpoint in visualApp.exe this may due to a corruption of the heap and the assert comment : If this ASSERT fails, a bad pointer has been passed in. It may be totally bogus, or it may have been allocated from another heap. The pointer MUST come from the 'local' heap. any ideas ? thx -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=16903#16903 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Hi Ulrich
no it is just a pointer inside a visitor.
here is a part of my code
void CPrintSceneGraphVisitor::apply(osg::Node node)
{
osg::Geode* geode = dynamic_castosg::Geode*( node);
if(geode)
{
osg::MatrixList matrixList = geode-getWorldMatrices();
const osg::Geode::DrawableList list = geode-getDrawableList();
m_stream drawable count : list.size() std::endl;
...
}
}
