void vtkImageData::GetPoint(vtkIdType id, double x[3]) is not thread-safe
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
The function "void vtkImageData::GetPoint(vtkIdType id, double x[3])" calls the non-threadsafe function "double *vtkImageData::GetPoint(vtkIdType ptId)", which makes both functions non-threadsafe.
