Class PwRivaraBisection

jv.object.PsObject

jvx.geom.PwRivaraBisection

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, PsUpdateIf

public class PwRivaraBisection
extends PsObject

Rivara bisection algorithm on triangulated surfaces. This class adaptively refines a marked subset of the triangles of a triangulation.

A cache mechanism is added to the element, vertex, and neighbour array. Each array has now a used size and a maximal size. Each time when the used size is greater than the maximal size the array is increased by caNewSize entries.
