Class AbstractContourGenerator

java.lang.Object
  org.jzy3d.contour.AbstractContourGenerator

Direct Known Subclasses:

MapperContourMeshGenerator, MapperContourPictureGenerator

public abstract class AbstractContourGenerator
extends Object

The AbstractContourGenerator provides various utility fonctions to compute core contour matrices. A concrete generator should implement computeHeightMatrix() according to the input object on which one desire to compute a contour (Mappers, Shapes, etc).
