Hi Craig, I don't understand what you said. I thought that nvidia cg offers frame buffer object to read data back from graphics card.

The graphics processor on the video card is not designed to send rendered output back to the main processor. OpenGL instructions come in one end, and rendered output goes out the other end ... to the monitor. It's unfortunate we can't intercept this data. Solid modelers such as Blender could probably use it, too. Maybe someday there will be enough market demand for the hardware to change. Craig.
