Sorry about that - we're using an Intersense IS-900 tracker.

I'll try the .preTrans, but could you please explain to me how it differs from view.translate? The vizard help file only explains that it "will pre-multiply the matrix with the specified translation", which I don't quite understand. Does this mean that it works with the node's local coordinates instead of the global coordinates? This is what we need, so the viewpoint is always + 0.13m in front of the tracker, not .13m frontward in z-space.

Thanks!
