Hi,
I'm trying to implement a simulation using for example a "ping pong"
implementation of render to texture (similar to the gameoflife example in osg).
I'm using osgPPu for the rendering part of my simulation and I would like now
to integrate the processing of the simulation on the GPU through osgPPU in some
way.
For now, I have something like that:
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
My idea was to add a UnitInOut as child of processSimulationUnitInOut. This new
unit is initialized with an output texture (like outputUnitInOut) I thought
then that I could deliver the new processed texture to unitTexture through a
NodeCallBack by the call of unitTexture->setTexture( unit->getOutputTexture()
). But it doesn't work, the same if I try to copy the image data from one
texture to the other.
Do I do the right way or is it totaly wrong or impossible that way ? I could
use the gameoflife example but I don't see how I could integrate it.
Thanks a lot in advance for all your advises,
Vincent

Thank you!
Cheers,
Vincent
