I was just wondering how 3d games like Quake3 (well not just shooters, every game is 3d today) run so fast with so many objects on the screen. My programs run really slow when I display only 1 or 2 objects!

aannnd especially somekind of Datasorting (BSP, Octrees,..)

this speeds up everything, cause it filters out objects that can''t even be in the view, can''t collide with the player or other things....
so it doesn''t matter if your main collision detection routine, your main drawing routine, or other stuff is slow, cause most of the triangles/objects don''t even get to this test...
(Can u imagine how fast it gets if even your hardest case routine is fast? wow! ;-)

cya,

Phil

1 or 2 models!!! You must be running in software or have very complex models. Hardware and hidden surface removal make games fast.
