a. You can scale movement using the
<link>.postScale command:
Code:
tracker = vrpn.addTracker('PPT0@hostname',0)
link = viz.link(tracker,viz.MainView)
#Scale X and Z movement by a factor of 2
link.postScale([2,1,2])
b. If you want to scale the Y data use the command above. If you want to add some value to the Y data use:
Code:
link.postTrans([0,2,0])
c. The position in both PPT and Vizard are in meters so there is no conversion necessary. If this does not answer your question please explain it some more.
