We've been working on expanding AbFab3D to handle more Volumetric Scultping capabilities. There is a new post here that shows off some of the cool new capabilities: http://abfab3d.com/ Currently AbFab3D is a Java programmer library. We're considering adding some scripting capabilities to make it easy to prototype creators. If your interested in making creators with AbFab3D feel free to contact me or just dig into the code. It's very server friendly and can make some really cool objects. And a teaser image attached.
