QRT/!!ReadMe

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.

!QRT is a Public Domain ray-tracing package that
originated on another machine and has been fully
converted for the Risc OS machines.

Double-click the application to run it, then drag
one of the directories (Building or Mirror) on to
the !QRT window. Ray-tracing can take a VERY long
time.

The resulting image is a sprite (called IMG)
located within the appropriate directory.

Full documentation of the program plus its world
description language can be obtained from most
PD libraries.
