has some info. I copied this text from the press statment, so you don't have to go out looking for it:
Coinciding with the release of SOFTIMAGE|XSI v.3.0 software, is a new crowd simulation toolkit that introduces digital character choreography and direction to the 3-D effects industry. The toolkit is a sophisticated behavioral animation and crowd simulation system that incorporates full-featured behavioral scripting, visual state-graph editing and dynamic motion synthesis.
The new crowd simulation subsystem, already used by top animation and effects companies in the industry on films like ‘The One’, ‘Napoleon’, and ‘The Scorpion King’, offers a production-proven, high-performance and interactive simulation pipeline for automating behavior for interactive objects, such as flocking, swarming, or 3-D characters in a crowd. With these new features, users can quickly build simple to highly sophisticated multi-object animations involving up to thousands of characters for pre-production visualization and direction to final production, while maintaining the ability to tweak and perfect the results at any time.
“When Softimage showed us the new crowd tools, I decided right there and then it would be the platform for us,” says Jason Barlow, lead character animator at R!OT. “We used it in ‘The One’ to help us realize the vision of director James Wong for a scene involving 1,500 prisoners, all CG, with different behaviors. We had talked to all the other vendors out there and no other platform could have done the job and in the short time we had. We also used the XSI crowd subsystem on ‘The Scorpion King’, where we saved a lot of time and money and were able to keep actors and stuntmen out of harm’s way.”
With SOFTIMAGE|XSI v.3.0, Softimage continues to drive the art of character animation with new cutting-edge additions to character construction and setup, such as options for quickly generating fully customizable, film-quality biped and quadruped set-ups and rigs. The SOFTIMAGE|XSI v.3.0 system provides additional flexibility, higher levels of interactivity and simplifies the creation of sophisticated characters. These new tools are also perfect for smaller shops that previously could not afford the investment necessary to develop such high quality characters.
