Detailed Description

template<class TInputImage, class TCoordRep = float>
class itk::RayCastInterpolateImageFunction< TInputImage, TCoordRep >

Projective interpolation of an image at specified positions.

RayCastInterpolateImageFunction casts rays through a 3-dimensional image and uses bilinear interpolation to integrate each plane of voxels traversed.

Warning:

This interpolator works for 3-dimensional images only.
