Reservoir Hill writes "Stanford computer scientist Vladlen Koltun says the inability of casual computer users to build 3-D objects — you practically have to be a sculptor — is an anchor holding back the promise of virtual worlds and games. "There is a very, very tiny community of people around the world who are skilled at creating three-dimensional objects," Koltun said. "And they are the ones who do it all." Koltun and his team set out to prove that object construction can be sophisticated without being difficult, beginning with trees. Botanists have already cataloged and categorized the trees of the real world in great detail. Koltun's group has incorporated that data into a powerful mathematical engine that creates trees using about 100 different tree attributes, all of them almost infinitely variable. How thick is the trunk? How big the leaves? How are the limbs spaced? The result is a new, intuitive way for individual users to create unique trees by simply using a mouse to seamlessly navigate through the entire "space of trees," changing appearances by changing direction. A gallery of trees and the software to create your own is available for free download."
