jvx.geom.PwNoise

All Implemented Interfaces:

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

public class PwNoise
extends PjWorkshop

This workshop moves all vertices of a PgPointSet randomly away from their original position. The random direction may be constrained to vertex normal or tangential directions. Boundaries and marked vertices may be kept fix.

Version:

21.01.07, 2.10 revised (ah) Method setGeometry() now overloads PjWorkshop.setGeometry.
30.03.03, 2.00 revised (kp) Better sync with PjWorkshop concept, update mechanism.
30.03.03, 1.60 revised (kp) Update element normals if they exist and normal update enabled.
12.02.03, 1.50 revised (ur) Handles moved to here from info panel class, frequency is now independent from new noise.
25.04.02, 1.40 revised (kp) Some tunings.
25.04.02, 1.30 revised (ur) Bug in updating removed, some tunings.
23.01.02, 1.20 revised (ur) New option: Keep boundary unchanged.
