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.

3D Graphics: A New Dimension (Part 4) By Dave Acton Run this application to open a directory containing the programs from the fourth part of the series on 3D graphics. Note 1: Before running any of the example programs, double-click on the BAU3D module to load it, and double-click on the Obey file ThisDir to set the CSD properly. Note 2: If you have Risc OS 2, you must load the ColourTrans module before running any of these programs. This module can be found in the !System.Modules directory on Applications Disc One. Double-click on 3DDemo3+ to see a rotating cathedral inside a contracting and expanding clipping window. Press ESCAPE twice to return to the desktop. NOTE: If you have a slow machine, then the image may flicker quite a lot. The source code for the BAU3D module is contained in BAU3DSrce and inside the Source directory. The cathedral object definition can be found inside the Objects directory. For more information, see the article on page 89. � Copyright BBC Acorn User 1993
