Computer Scientists Grow a Better Virtual Tree

Reservoir Hill points us to a story about a group of computer scientists who are taking steps to bring the creation of 3-D worlds to the casual user. As a proof-of-concept, Vladlen Koltun and the Stanford Virtual Worlds Group, using data collected by botanists, have developed software to create virtual 3-D trees with roughly 100 different tree attributes, all of which are highly variable. Quoting: "The inability of casual computer users to build 3-D objects - you practically have to be a sculptor, Koltun says - is an anchor holding back the promise of virtual worlds. Koltun's software, Dryad (a tree nymph in Greek mythology,) lets users move through the 100-attribute tree space in a fashion similar to navigating city streets on Google Maps. As in real life, not all trees are equally desirable. Since no single user is capable of mapping out the best parts of the enormous tree space, this mapping of desirability is done collaboratively, leading to continuous refinement of the software."

I'm underwhelmed.

Generating visually complex plant like shapes has been a mainstay of 3D modeling software and demos for a while now. These guys might have worked with botanists and expressed hundreds of attributes, but I don't see how this will translate to better tools for 3D modeling in general.

Who's got this program to work?

Has anyone here downloaded Dryad (the software) and got it to work?

I tried it a few weeks ago when I first heard of (believe it was 1.0 not the January 1.1 release). On two beefy computers the program would start then proceeded to crash after 20 seconds of interacting with it. I never saw a tree. I wasn't worried about specs as the one computer has 3 gigs of RAM and an 8800.

I'm all for releasing public alphas or betas, but was surprised at how brittle it seemed considering the lack of warning or documentation.

I for one noticed the excellent tree models in Feralas in WoW, that area is just downright gorgeous. If they were more realistic they would probably be even more aesthetically pleasing. The human brain is pretty good at picking up on unnatural things so making trees as realistic as possible will make the game look better even to those who never look for the trees.
