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, |
KDL looks cool! Defintaly a possible solution for you.
Keep us updated =), would love to see how your experence with KDL is. |
