Detailed Description
PrincipalCurvaturesEstimation estimates the directions (eigenvectors) and magnitudes (eigenvalues) of principal surface curvatures for a given point cloud dataset containing points and normals.
- Note
- The code is stateful as we do not expect this class to be multicore parallelized. Please look at NormalEstimationOpenMP and NormalEstimationTBB for examples on how to extend this to parallel implementations.
