   Raycasting engines
  Does anybody know where there are some good tuts on raycasting or an engine? Not that im gonna use it of course.
  no theres no reason you should. i wrote a raycaster before i ever knew it was an existing thing: i thought i really had invented something.. . so its far from impossible to do without someone taking you by the hand. all you need is to know the math behind ray-plane intersection and a point-inside-tri-in3dspace algo. sure theres plenty of possible improvement after that, but i dont suppose you were aiming at realtime anyway?EDIT: hmm seems i messed up raycasting and raytracing once again [edited by - eelco on May 12, 2003 8:22:14 AM];  The best: http://www.permadi.com/tutorial/raycast/    -~-The Cow of Darkness-~-
