Detailed Description

template<typename T>
class npl::LanczosInterpNDView< T >

The purpose of this class is to view an image as a continuous 3D+vector dimension image rather than a 4+D image. Therefore all dimensions above the third are cast as a vector and interpolation is only performed between 3D points, with the 4th dimension assumed to be non-spatial. The would be applicable if the upper dimensions are of a different type than the first 3.
