View Full Version : How to get a fast collision detection with BSP-Files
07-07-2002, 11:03 PM
Hi, i have been loading BSP-Files the last few days (Quake3-BSP).
Well... i addet a simple spherical collision that checks every drawn face for collision... but it is really damn slow.
Is there a way to speed up my collision?
Is there a structure for brushes (convex volumes) in every leaf you draw on screen. Make the collision test with the planes of the brushes instead (check if one point is inside or outside of a brush). I've done that and it's very fast.
