Hi Patrick > So if understand correctly, I could pass a texture (for > each frame) or just have the camera attached to the PPU > processor... Is that correct? > Yes, you could just attach a texture (which is updated somewhere externally) into the osgPPU and work on it. You will need then something like following: osgPPU::Processor->UnitTexture->UnitX (so your pipeline). This would provide the texture you have attached to the UnitTexture into the pipeline and you can start work on it. Otherwise you just attach a camera to the processor and it will then automaticly provide camera texture to the pipeline.
