Projection Offset Problem I ham having problems understanding a projection and have attached an image to illustrate. The point can be found by: Zfar / (Zfar-Znear) and subtracting (Zfar * Znear) / (Zfar-Znear) The subtracted fraction is what I don't understand. It is an offset of the transformed point and is a discrepancy. Apparently it is pretty easily understood, but I don't understand it. Could somebody please explain? I have a feeling that I still won't understand it, so easy does it, please! Thank you, Josheir https://ift.tt/eA8V8J
