Yes thank you

Hi,
 
if you derive your image filters from vtkThreadedImageAlgorithm, you gain
multithreading capabilities :

For custom multithreaded execution, there exists a dedicated VTK object:
http://www.vtk.org/doc/nightly/html/classvtkMultiThreader.html
 
I use it efficiently together with vtkMutexLock.

Hello all,
 
I've been wondering if there exists a way to implement multi threaded
filters in VTK. As an example, there exists in ITK an interface
(itkImageSource) which allows to create multithreaded filters by
implementing some of its methods, they are called automatically during
execution of the pipeline.
 
If this is not the case, how can this be done in a correct, "effortless"
way?
 
Thank you very much,
