Detailed Description

Abstract class for steepest descent on a polygonal non-manifold.

Date

2006/04/06 16:46:43

Revision

1.4

This class is an abstract filter used as base class for performing steepest descent on a non-manifold surface made of convex polygons (such as the Voronoi diagram) on the basis of a given scalar field. Steepest descent is performed on the edges of input polygons with a first order approximation.
