Hello folks. I badly need help for my research. I want to do my own version of Photon Mapping in Cg. I'm stuck and cant seem to figure out how to do multipass shading in Cg. I'm using the cggl (Opengl) extension of Cg not the directx extension. Can someone help me on this please. If you have an example for a multipass Cg shader I would really appreciate it. Thanks so much!!!

you don't just make cg do a multipass shader (unless you're using cgFX, and even then you need some custom code to handle the multiple passes), you do it yourself.
