Hi OpenGL guru:
One camera (call it agent_cam) renders an image in front of character, and thus excluding the character.
The other camera (call it audience_cam) renders an image from a point located somewhere back of the character in order for people to see the character and environment.
Then the rendered result for agent_cam should be hidden (or so) for the people not to see the rendered image. But still I want to read the buffer (or so) used for the agent_cam rendering, in order to read pixels of the buffer for my own computation.
Any comment for doing it would be very appreciated.
This animation is being done under FLTK
