Description copied from interface: Polygonizable

Defines the data source on which the polygonization depends.

Specified by:

getPolygonizableSource in interface Polygonizable

Parameters:

gs - the current graph state

Returns:

the data source

getPolygonization

public Polygonization getPolygonization()

Description copied from interface: Polygonizable

Defines the algorithm which is used to decompose the data into a polygon mesh representation.

Specified by:

getPolygonization in interface Polygonizable

Returns:

polygonization algorithm

getPolygons

public Polygons getPolygons()

getVisibleSides

public int getVisibleSides()

newInstance
