Hi,
have a look at the osgstereomatch example, there multipass and MRT are
used together. Also have a look at osgPPU and osgCompute which are
external to OSG.
For simple flip-flop FBO use you can look at osggameoflife

Hi,
I'm a newbie on OpenSceneGraph. I have written an OpenGL program which do
computations in screen space. In my program, frame buffer objects (FBOs) with
multiple render targets (MRTs) are used.
My code looks like:
first pass:
render scene:
- use GLSL shaders
- write data to FBOs' attached texures
second pass:
- use GLSL shaders
- wirte data to FBOs' attached textures using textures from
first pass
third pass:
- use GLSL shaders
- wirte data to FBOs' attached textures using textures from
previous passes
....
last pass:
- use GLSL shaders
- render to the textured screen filling quad
I would like write this program with OSG. Can anybody give me ideas how to do this? What kind of parts from OSG may I use. What will the scene graph look like?
Thank you!
Cheers,
E.W.
