Avatar bone rotations respect to world

[MiamiTodd]

I would like to get in orientation information on a persons limb orientations and map those values to the bones of an avatar. However, the information I am getting in will only be the orientations. When I make the changes, I would like to just be able to specify the final orientation of the limb segment and have the bone be set to this, but retain the positional information so that the limb segments don't end up in different portions of the world.

Is there a way to perform such transformations in Vizard?

Thanks,
Todd
