Choice of projection "plane" (d/z_p) in a 3d to 2d projection setup

26 December 2012 - 05:27 PM



For fun and profit educational purposes I am rolling my own 3d to 2d projection code. As part of defining my view frustum though, I have some qualms about the choice of plane on which to project the points found to be in the frustum. In some guides, they choose the plane z = z_near, but in some sources they choose a more or less arbitrary plane z=z_p where z_near < z_p < z_far. Is there an advantage to any choice?


As far as I understand it, it doesn't really matter, but I wanted to ask in case my understanding is not correct... :)
