Hi all,

I am interested in using the FindCell method of the vtkStaticCellLocator from multiple threads. Is this save to do?

In the VTK documentation I noticed, that the vtkDataSet also has a FindCell method with this information:

> THIS METHOD IS THREAD SAFE IF FIRST CALLED FROM A SINGLE THREAD AND THE DATASET IS NOT MODIFIED

For the vtkStaticCellLocator I did not find this information. Does this mean that vtkStaticCellLocator::FindCell is not thread save or is this info just missing from the documentation?

Cheers,  
Lukas
