Yeah, I know about the suit, the cameras, and all that stuff. It's pretty cool, don't you think? And I guess I am needing a motion capture system, not a motion tracking system. I would really like to have one of these things dispite the amount of money I'm sure they cost. I just don't want to drive myself into a hole by buying this thing and not knowing how to hook it up and everything. From the looks of all the wiering and setup, it looks fairly complex. Motion Analysis Co. (link to their site in 1st post) has a downloadable catalog that has a lot of items in there, but I don't see one of those grid things you step on. They also have a sword-fighting animation that is super cool. It looks so realistic! I imported a body mesh I had previously made, then attached it to the skeleton, then added a simple poly sword and let'er rip. This just makes me want it so much more.
