     Updated by Bill Soo... instead of 25 fps, it runs at 60 fps now! Which is an astonishing framerate for VB Again some pretty unique code from me. This program is a _realtime_ raytracer (not raycaster!). I ported it from C++ to VB, and it still runs pretty fast. It also shows you how to use SetDibbits to change all the bits in a picturebox with just one call. You can zoom in and out, add more spheres by changing a few variables/constants in the code. Light-positions can be set by the scroll bars and changes will be visible directly! Note: Please compile this program, or you will receive ~1-2 FPS from the IDE. I would appreciate some votes, people, so that I can still think my (unique) work is appreciated =-) Update: I've moved some math functions inline, and improved the code wherever it was possible. 10fps more now! Do not forget to compile the program though... Original source is also included. I'd really appreciate if you vote for this code guys.

  1. Re-scan downloaded files using your personal virus checker before using it.
  2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.
  3. Scan the source code with Minnow's Project Scanner

If you don't have a virus scanner, you can get one at many places on the net
