This page documents how I created the figures in this paper. The hope is that those interested in the method can experiment with and learn from the software that was written for the paper. These instructions below assume version 1.7 of teem.
Unlike the previous paper in my ongoing experiment in "reproducability in scientific visualization", most of the figures were actually rendered directly into PostScript (EPS) files, and never existed in raster form. Because the means of rendering directly to PostScript are relatively new to Teem, there aren't standard Teem binaries for making the figures. Instead, for the time being, "test binaries" are used:
Because the figures are EPS files, they've been rastered for the sake of these pages with GhostScript, through a simple Perl script I wrote called eps2ppm.

If you go through the work of regenerating any of the images or figures using my software, some acknowledgement of Teem (http://teem.sf.net) would be appreciated but is not required.|
Explanations of why these commands do what they do will be sparse until I have time to write up something more thorough, so the commands may be pretty cryptic. Again, the goal is not to be a general tutorial on Teem usage (you're welcome to help me write such a thing!), but to allow regeneration of the figures from scratch.
