Raycasting engines

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
