<div> </div><div>however vtkMultiProcessControler is an abstract class, so i am unable to use it as shown in the exmaple.</div><div> </div><div>Another example suggests the same using vtkMPIController without MPI to get a threaded controller:</div>

<div> </div><div>However for me this doesnt seem to work, I get mpi errors if i try to inialise the MPIController without MPI.</div><div> </div><div>Doesnt anyone have any hints on how to make a threadedcontroller work in vtk6.0.0</div>
