question on linking markers in Vicon

Hi, I know vizard can link the vicon marker to some object like:
#Add a vicon marker
marker = viz.add('vicon.dls')
#Add a 3d ball to represent the marker
ball = viz.add('white_ball.wrl')
#Link the 3d ball to the marker
ball.link(marker)
Then is it possible to link a set of markers into vizard? Now I have vicon motion capture system and we capture human's movement. there are 53 markers in total for a subject, is it able to connect these markers to an avatar in Vizard directly? I know I can use live character. Thanks.

For motion capture our solution uses Motionbuilder to get the motion capture data, perform the inverse kinematics and map that to a skeleton and the Live Characters plug-in to stream the skeleton data into Vizard.

Hi,
I am aware if I need to use Vizard's avatar i have to use the livecharcater, but if I can export a skeleton from 3dsmax how can link the makers to the 3dsmax skeleton?
is there any way can be used to control avatar through Vicon and Vizard without livecharcater?

Mojo,

You can access the Vicon data through Vizard's Vicon plug-in.

It is possible to animate an avatar with a tequniqe know as inverse kinematics. Inverse kinematic maps Vicon points to avatar bone rotations.

This is a hard problem. Seach inverse kinematics in google for resources.

HI Paul,
Thanks for your post. I know the solution would be the IK and it is a hard way if I choose. is there any possibility to use PyKDL package?
Thanks,
