Not a finished image yet, but some development on the grassy sphere. Rendering
grass is quite interesting; placement algorithms seem to be far more important
than the actual grass geometry... this rendered in 4+ hours (AA with radiosity
really hammers it).

Very nice. Could you get away with just using one triangle as grass?

Looks good, but 4+ hours! Yikes! Have you tried Blender for this sort of
thing? :)

I think I would have done the radiosity without all of the grass and saved it,
then loaded the stored radiosity data for the final trace. I find this to be
much faster, and the results are rarely different.

Yikes indeed, but it's not a top-end machine. It renders in about 4 minutes
without the radiosity or AA. I've not really used Blender for anything, and
when I do I'll need to take a good run at it, to judge from opinions here!

I'll give it a try.
