Here for your enjoyment is a technology preview/demonstration of a
raycasting and rendering algorithm I have developed as part of my Apple
II 30th birthday-retro-game-just-because-I-can thing.  Reminiscent of
Wolfenstein 3D, it runs on a standard 1 MHz 48K Apple II+ (or II w/
Applesoft in RAM/ROM) or greater.  Only a joystick is required.  It is
possible to run it on an emulator, but I highly recommend using real
hardware with a color monitor.  Accelerators make it run too fast, so
disable them if you want the controls to be sane.  I present it as a
140K DOS 3.3 disk image compressed with gzip.  Download with this URL:

That's pretty cool! I fired your demo up on my II+ and it ran great. It
was surprisingly smooth. Lores is normally boring but you really
brought it too life. David Schmenk is definately a geek! ;)

I'll look forward to your improvements as they come along. Nice job.

Thanks! Lores definitely is under-appreciated. The texture artwork is what will make or break the 3D feel of the rendered scene. I tried a few different ideas, but horizontal details work much better than vertical details. I did have to add vertical details on the wall boundaries or else it all blended together.
