Despite the fact that good mathematical software exists, the
production of high-quality computer images and movies is still a
difficult and time-consuming process. We used a variety of tools to
produce the pictures for the gallery show. The
"Torus Triptych" was
generated using a program called fnord developed at Brown
University, but not generally available to the public. The
"Triple-Point Twist",
"In- Outside the Torus" and
"Math Horizons" images were
created by an ancient piece of custom software for SGI workstations
developed by Nick Thompson as an undergraduate at Brown University.
Remarkably, it still runs beautifully after more than 10 years without
maintenance. The three images in celebration of Dirk Stuik's 100th
birthday were generated at the graphics laboratory at Brown University. The
remaining images were produced using geomview, which
is distributed as freeware by the Geometry Center, though it runs only on
unix workstations. The MPEG movies that are part of the interactive
gallery were created using geomview and its associated
StageTools
modules.
The images were produced first as high-resolution TIFF files,
but some post-processing was done after creation (e.g., combining the
separate images to form the necklace and tetraview sequences) with a
variety of image tools on both the unix workstation and on a Macintosh.
These tools included the ImageMagick library under unix, and
GraphicConverter on the Macintosh. The final results were
printed as Ilfochrome images at 20 by 24 inches and mounted on foam-core.
The images in "Torus Triptych"
were arranged so that the 20 by 24 prints could be cut in half and joined
end-to-end to form 12 by 40 or 10 by 48 panels.
