Hi,
I used successfully GL_FEEDBACK one time. By successfully, i mean : the GL_FEEDBACK only returns the triangles THAT ARE DRAWING.
But, i had to change the code: i am drawing a face, and the camera was IN the face. So, i have moved the camera OUTSIDE the face, and now, the GL_FEEDBACK doesnt work.
The same buffer i am using get ALL the triangles of the face : those which are drawing, and also those which are hidden by some triangles.
I really cant understand this change of the behavior of the FEEDBACK MODE.
Do you have any idea ?
Thanks a lot.
