I need to get all equations of all six planes from projection matrix. Is it possible? How? Edited: Explanation: I'm in clipping stage of my 3d engine. I store all about clipping frustum in matrix, so I wonder if this is enough or I have to store it by easiest way. [edited by - TheVoid on June 2, 2004 11:55:58 AM]
