Class GridTesselator

java.lang.Object
toxi.geom.GridTesselator
All Implemented Interfaces:
PolygonTesselator
Direct Known Subclasses:
GlobalGridTesselator, LocalGridTesselator
public abstract class GridTesselator extends Object implements PolygonTesselator
This is an implementation of the PolygonTesselator interface and abstract parent class for tesselating 2D polygons using a grid of additional points created within the polygon. These inlier points are connected to the original polygon vertices using a DelaunayTriangulation. The quality and final amount of triangles used can be adjusted via the number of additional grid points. This class currently has two concrete implementations: GlobalGridTesselator and LocalGridTesselator .
