I currently use Tcl/Tk, Perl, PHP, and ImageMagick for procedural graphics.

Procedural graphics refers to image manipulation or creation that is done by formula or script instead of interactively. POVRay ray tracing is a form of procedural graphics, as is any fractal viewer or landscape generator.

Very often in web site creation it's necessary to produce thumbnails at various sizes from a list of source images. Ryan "Tet" Dewalt wrote a Perl script to walk a directory and make a Web gallery from the contents. I have upgraded it somewhat to add features.

I'm also interested in Functional Imaging that renders an equation into an image.

o xyTOchex_colorGradient {rxyTOxy_swirl 8} {nraTOra_slice 110} xyTOxy_radInvert

At NIMH it has often been helpful to render test data into an image for sanity checking. Many misconfiguration and data corruption problems become evident when the data is visualized.

StippleGen transforms images into dot patterns or line squiggle drawings. These can be drawn by plotters or CNC machines.
