[vtkusers] VTK Renderer multithread problem

[maaschn]

Hello,

I've got a multithread application in which one thread collects points and
fills them into a polydata object which it gets passed in the constructor
from the main thread which keeps the pipeline. I am using Qt and a Mutex
lock. It nevertheless happens from time to time that my application crashes
when the Renderer calls the render funtion. Then there is an unvalid cell id
while transversing the polydata. I think it must have something to do with a
collision between those two threads. Has some experienced something alike?
Or does someone knows what I could do to get this method threadsafe?



Thanks in advance

Maaschn
