Hi Art, I got my example of ping pong working. Here is the structure
processor |-> unitTexture (to initialize or change the input texture through the cpu) |-> processSimulationUnitInOut (will contain the shader for the processing of the simulation) |-> blurUnitInOut |-> computeNormalsUnitInOut |-> outputUnitInOut to get the ouput texture (the same as writen in my first post). Then I set an output texturet hat has the same parameters of the input texture to processSimulationUnitInOut with processSimulationUnitInOut->setOutputTexture(processSimulationOutputTexture2D, 0);. Then I add a osg::Camera::DrawCallback to the camera of the viewer (that is also the one of the processor). In the method operator() of this callback I extract the output texture from processSimulationUnitInOut with osg::Texture2D* t0 = (osg::Texture2D*) processSimulationUnitInOut->getOutputTexture(0); and give it to the input unit texture (unitTexture) with unitTexture->setTexture(t0); One can do ping pong with several textures because of the mrt parameter of setOutputTexture and getOutputTexture, and it works. I hope I was clear enough. If not, do not hesitate to ask me. Vincent ... Thank you!
