Hello, Ive been doing some work on my engine(loading quake3 bsp's) and now need to move on to collision detection. Unfortunately i have no experience with 3d collision detection and small amounts of 2d collision detection. Im not a 3d math wizard and have basicly been learning it as i go/need. Does anyone know of a good place to start with this quake-3-bsp-collision-detection. I would like to start by accomplishing some camera-world collision detection, and then move on to a realistic camera(jump, gravity, Etc.). Thank you!
