Hy. I try to debug an application , but it seems that opengl don't have a valid opensource debugger. My idea is to write a project that output all my data from fragment shaders to the texture with a protocol , a 0 separator for ex and read this texture and find all real data in the gpu. Is possible? There are some opensource project that do this ,I'm reinvent the weel ? thanks

gsdevil?
but i must test cg shader , it work wit cg?
thanks.
