Ok, here is the scenario: I have motion capture data from a Vicon system in the form an ASCII file containing the XYZ coordinate POSITIONS of some point lights. Considering that within the BVH hierarchy, the channels ask for XYZ(or whatever order) ROTATION, if I convert my XYZ POSITIONS to poser units, and then enter them into the correct format(following the hierarchy) of the motion section of a BVH file, should this correctly animate a figure, or whould I need to have the XYZ ROTATION info to do this??? Any and all help is MUCH appreciated!

Can I borrow your Vicon for a few hours? :) Anyways, no, you need the rotations (the hip has position and rotation, but all other joints are rotation only). I assume this file is in trc or htr format, so the only option that I know of is bringing it into Motion Builder(www.kayadra.com) and converting it to bvh. -Mark
