Detailed Description

NearestNeighborSampler, TrilinearSampler, TriquadraticSampler and TricubicSampler.

Note

These interpolators employ internal caching for better performance when used repeatedly in the same voxel location, so try to reuse an instance of these classes more than once.

Warning

While all the interpolators defined below work with both scalars and vectors values (e.g. float and Vec3<float>) TrilinarSampler::zeroCrossing and Trilinear::gradient will only compile with floating point value types.
