I need to prepare for my exam and this is the probable question for the test. Given a frustum method such as frustum(-1,1, -0.5, 0.5, 1, 2) how to convert this to a projection matrix? The above example from my textbook but the writers don't define it in detail. If anyone can explain this in detail, I'd appreciate very much.
