QRT is a ray tracing image rendering system that runs under a variety of operating systems. It has a free format input language with extensive error detection and reporting capabilities.
QRT source and executable is Copyright 1988 and 1989 Steve Koren. It may
be freely copied, modified, and distributed under the following
conditions:
1) Notice of any changes is posted and distributed with subsequent
versions
2) Neither the source nor executable is sold for profit.
3) This message is distributed unmodified with the source and
executable.
Any images created with QRT are yours to do with as you wish.
The final IFF picture will have a filename of Image.ILBM.
QRT and QRTPOST were written by Steve Koren. RAY2 was written
by D. Wecker and is Copyright 1987. RAY2 creates a HAM image
from a bitmap representation produced by QRTPOST.
QRT should be run in the background with a low priority and
its output file should be placed on a virtual disk. It will
produce 400K of output, so extended memory is recommended.
Stack size must be increased from the system default of 4000
bytes with the STACK command. The exact size necessary varies
with the image, but 50000 to 60000 bytes is usually safe.
When QRT is running, you can check its progress by getting a
directory of the device on which the Image.RAW file is being
created. A full image has 400 scan lines, and will be just
short of 800 blocks when complete. Thus, divide the blocks
so far by 2 to discover how far into the image QRT has
processed. Different parts of an image might be created at
different speeds.
