3d raycasting

Has anyone seen any easy tutorials for 3d raycasting? I find it tricky to get my head around applying calculus to a 2 dimensional byte array (the byte array being the "map") to figure out what the user can see on the screen.Thanks in advance

There is j3d, but if you can create something faster then i want it. I know of a raycasting applet and tutorial, I'll find them for you.
