[vtkusers] Moving an actor, after about 1.5 hours.

[Richard Frank]

We are moving an actor(s) (  assemblies ) in multiple QtViews that represent a set of surgical tools.

In one of our unit tests, the tools are moved for approximately 1 - 1.5 hours and after that time period the tools no longer " move" during rendering, even though different position data is being set to them via SetUserTranform. 

There are, as far as we can tell; no reported memory leaks; no memory overwrites, and no reported OpenGL errors. When I trace into vtkOpenGLActor nothing appears to be amiss. This is on two different machines one with a quadro 5000m and the other with a high end geoforce card.

If we use a keystroke to remove and add the actors back into the renderer, this will usually fix the problem, but we want to get to the root cause.

I'd appreciate any tips on how to debug this.


Thanks
Rick
