Creating a 3D Perspective Projection Matrix

Recommended Posts

I am reposting this because I don't know if it was wise to place this comment in my Liteweight Matrix lib thread. If it is better for this post to remain there, admins please forward comments to that thread. Any who, here is my post. "Hmm... I am interested in defining a method which would calculate a perspective matrix given a near point. I know the formula for this would be (N * X/Z, N* Y/Z) However, how would I set this formula up in a matrix? Thanks in advance! "
