Detailed Description

A class to support FTMachines get their convolution Function.

Intended use:

Public interface

Prerequisite

VisBuffer module

Etymology

WP for W-Projection ConvFunc => returns the convolution functions

Synopsis

FTMachines like WProjection and MosaicFT need convolution functions to deal with directional dependent issues..\. this class and related ones provide and cache such functions for re-use
