[Paraview] SpaceNavigator , builtin: (version 10.1)

[Nikhil Shetty]

Hi Ricardo,

I think part of the problem is that device inputs are not synchronized with
the rendering. And with everything done in a single thread in VRPN plugin
(pv 10.1) we didn't have a mechanism to throw away old inputs from the
space navigator and use the latest. So what happens is that all the inputs
keep getting collected and processed one at at time and one needs to wait
till the queue is empty.

You could use some rudimentary mechanism like processing the n'th input and
discard the rest. This was our solution for head tracking before we put in
a framework to process device inputs.

So our new framework is multithreaded and solves this issue but you may
have to wait for some time to have that available.

Regards
Nikhil
