The Optitrack system is definitely Yoshi's software, you only need to look at his site and theirs. I am really glad that they got together, I think that's really much better in terms of support, etc. And I didn't mean to sound negative--okay, maybe I meant to sound somewhat negative--I guess I'm just really frustrated to have mocap dangling in front of me for years, seemingly just out of reach, while at the same time I can't figure out why it's taking them so long to bring it out. I'm generally a patient person--you have to be to animate--but I just want this so badly!
