[Paraview] VRPlugin - VRPN ModelTransformMAtrix Grab problem

[Emiliano Pastorelli]

Hi guys,

i am testing the VRPlugin (VRPN connection only at the moment due to the 
issues i had with the VRUI connection) with a Razer Hydra joystik.

The tracking of the position is fine, but when i connect one of the two 
joysticks and its three buttons to the grab of the ModelTransformMAtrix, 
i get a weird problem with the translate. The rotation and the reset 
word ones work like a charm, but when i click the translate world button 
(in the state file below, the Hydra.L2) the scene starts bouncing and 
flickering almost out of control. I see that it also translates, but it 
rotates around with this flicker also if i'm not even touching the 
tracked wand.

Any idea on what might be causing that?

Best,
H
