This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.

Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

PLEASE enter values for VIEWING X (200-3800 rcmd.), VIEWING Y (200-3800) and VIEWING_ANGLE (0-1920, where 1920=360 degrees etc...).

The program will take a screenshot of the rendered view, and store it inside the !AUARay application directory.

This early version is quite unstable, and is purely designed to give an example of how ray casting can be applied to C source code. Staying within the recommended coordinates is a wise move, and pay special attention to keeping the view point OUT of walls!
If you are using the program with the world file supplied, try 400,400,100
