Purpose:        Fast Computation of Heat recursive flow.
                        Thomas LU model.

                        Semi-Implicit solver using LOD multiplicative splitting
            (I - tau * A) * uNew=  uOld

                        LOD is ok, in isotropic situations

Member Function Documentation

RImage * RThomasHeatOp::filter (  RImage *    src, RImage *    dest = 0 )  [virtual]

Local full image filtering. Parameters: src  is RImage* is RImage source channel dest  is RImage* is RImage result/placeholder Returns : RImage* as result, Implements AbsRImageFilter.
