Method Detail

evolveParallel

public static boolean evolveParallel(PgPointSet geom,
                                     double dist)

Evolve point set in direction of the vertex normals. This method does not save the vertices of the geometry.

Parameters:

geom - geometry to evolve

dist - dist*vector determines the length of the translation vector

evolveVectorField

public static boolean evolveVectorField(PgPointSet geom,
                                        double dist)

Evolve point set in direction of the selected vector field of a geometry. This method does not save the vertices of the geometry.

Parameters:

geom - geometry to evolve

dist - dist*vector determines the length of the translation vector

Version:

25.03.03, 1.50 revised (kp) Take selected vf instead of first vf.
