It looks great, and has a great license. I made a SAGE
package for it too. If you do
./sage -i yafray-0.0.9
it should build yafray for you (I made an experimental package).
But it's a strange system to understand --
there doesn't seem to be much in the way
of documentation, and doing something as simple as drawing a sphere
seems really hard. (??) It uses xml and is used as a raytracing plugin
for blender. It's actively developed.
Anyway, I'm looking for a GPL-compatibly licensed replacement for
Tachyon3d, whose license is -- unfortunately -- not GPL compatible.

figure out their scene description language, it would appear that we'd
have to reverse-engineer it from Blender output."
