The Q3 demo version has just been released, check it out.
Also have a try of Animeeple for character animation!
It is new, it is very intuitive and it lets you:» Apply animations onto characters» Layer and sequence the animations» Edit animations using procedural modifiers» Render images and movies» Animate your Second Life™ avatar» Export content as FBX, Collada, BVH and XMLExporting from QUIDAM to Animeeple requires the COLLADA export plugin (included in QUIDAM Studio, this plugin can be purchased separately by QUIDAM users).

If you are interested in markless motion capture, drop by my other blog, PREVIZPOST I think it’s pretty exciting technology.
