Algorithms that can be converted to vtkSMPTools
vtkThreadedImageAlgorithm
This is the base class for nearly all the VTK imaging filters, and it is probably the most difficult one to convert. Its conversion is the highest priority.
vtkStreamer
This is the base class for vtkStreamLine.
vtkImplicitModeller
Uses multithreading for its internal structured data processing.
vtkImageMapper3D
Uses multithreading for its color mapping operations.
vtkEncodedGradientEstimator
Base class for vtkFiniteDifferenceGradientEstimator, which uses multithreading to compute image gradients.
vtkVolumeRayCastMapper et al.
All of the CPU-based ray cast mappers divide the ray casting among the threads.
Algorithms that cannot be converted to vtkSMPTools
vtkGeoSource
This is not an SMP algorithm, it uses vtkMultiThreader to create a single background thread.
vtkVideoSource
This is not an SMP algorithm, it uses vtkMultiThreader to create a single background thread.
vtkDataEncoder
This is not an SMP algorithm, it uses vtkMultiThreader to create a single background thread.
