Detailed Description

Class for grid to grid lookup tables.

This class is only for internal use by the Resmple function(s) of the UniformVolume class. The lookup table basically records for each pixel in the target grid, which pixels in the source grid it depends on, and with what relative weight each source pixel contributes to the target pixel. The contributions are computed as relative overlaps of boxcar-shaped pixel profiles.
