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 an arbitrary vector field of the 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
