NaturalPoint is demonstrating Arena, its full-body motion capture system, in the North Hall (Booth 6433). Starting at $5000, the system is in use by large game development and visual effects houses. Attendees can learn about Arena's latest features, which are being announced at GDC. Among the new features are: support for multiple actors, the ability to run up to 24 OptiTrack cameras running on one laptop, and more. The development team is on hand to answer questions about the technology and its applications.
