I hacked together something to generate bump maps from texture images
(though not specifically for RADIANCE) simply based on the intensity
gradients. Pretty trivial, but looks good enuff. Unfortunately, the
source wound up somewhere in the Twilight Zone(tm). Hopefully I can dig
it up, but it's really not that difficult to write from scratch.

See ya!
