Hey Radiance folks,
I've written a pile of scripts to convert USGS elevation data into
watertight trimeshes for 3D printing. While doing so, I had to make sample
renderings of lots of mountains. So, if you like mountains and like
Radiance, you might like these images.

I hope the renderings are good enough to warrant the shameless plug.
Details:
My own rockpng program converted the 16-bit PNG heightfield to a trimesh.
Meshlab-server did some automatic processing on the mesh. I used GMSH to
generate text and Carve to union that text with the model (all F/OSS).
Models are 500k-900k triangle Wavefront .obj files (easy to read and
write), converted to Radiance mesh format for rendering. The room was
modeled after my living room (down to including two large green trees out
the two windows), and rendering used an imagemap of my stone coffee table
and some rpict depth-of-field with -aa 0 -ab 3 -ad 16 for ambient settings
and -ps 1 -u+ -w- -lw 1.e-3 -ds 0.2 -dj 0.7 for rendering. The raw .hdr
images were dropped to 8bpp first, then reduced 4:1 for the site (less
noise doing it in that order).
