She specificall addressed the issue of using integer math. None of your vaunted standard references really go into any depth on real-time performance on low-end type processors. Her questions were not only perceptive, but very valid. There are also many other optimizations and "cheats" that can be used to speed up 3D rendering to approach real-time. These are NOT commonly published, and I have little doubt that I could point out a few that even you probably had not considered in your precious standard reference wisdom. I do not think that there was any attempt made to provide a "tutorial", nor one asked for! I would hearitly agree with those opinions expressed already that there are no questions that this forum is "too good" to deal with. To put it plainly, I think your attitude stinks! - Ed Rotberg - - Game Designer for BattleZone & S.T.U.N. Runner -
