Having posted the requisite reflective sphere image, I went through my old
POV-Ray files to see if there was anything worth sharing. Only one file
seemed sufficiently interesting to pass along.

The attached image is based on the Lucy dataset from
http://graphics.stanford.edu/data/3Dscanrep/. What made creating this image
fun was:

1) The floating point data in the Stanford dataset is stored big endian so
it had to be turned around before my Windows machine would understand it.

2) My clunky old machine ran out of memory long before processing 28 million
triangles so the image was rendered in strips. The Lucy vertices had to be
reordered to build nice solid strips.

The notes in the lower right were added post-rendering.

Really incredible! How long to render all the strips?

Very detailed model, but I'm sure it wouldn't hurt to run a triangle
decimation algoritm. It would ease rendering!

Oh, man.  I was hoping to see "entirely hand-coded in POV SDL," or at least
"made with Wings 3D." ;-)

But, "The Lucy vertices had to be reordered to build nice solid strips," is
just about as impressive.

Nice job!
