View Full Version : Field of view from glFrustum?

04-22-2003, 12:13 PM
People seem to be implying that glFrustum determines the field of view but how is that possible if it only takes 6 parameters. You are just defining a box that isn't necessarily centered at (0,0,0), how is the camera angle determined?

Have I got this wrong? I want more control than I can get with gluPerspective but I haven't found a clear explanation of glFrustum yet.

I gave an answer to this about a week or so ago. If the link below isn't enough explanation, let me know.
