ENH: Use new filters for isosurface extraction and plane cutting (!933) · Merge requests · Sam Horvath / Slicer

Andras Lasso requested to merge github/fork/lassoan/use-smp-optimized-filters into master Apr 10, 2018

Optimized versions of isosurface extraction and plane cutting filters have been introduced a while ago in VTK, but Slicer kept using the existing filters. Filters updated in this commit:

vtkDiscreteMarchingCubes => vtkDiscreteFlyingEdges3D
vtkCutter => vtkPlaneCutter

With default SMP backend (Sequential), performance may be slightly improved. With TBB backend, computation time for complex surfaces (e.g., obtained by thresholding a noisy grayscale volume) is decreased by 30-500%.
