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
invalid @link 
computeHeightMatrix()
according to the input object on which one desire to compute a contour (
invalid @link 
Mapper
s,
invalid @link 
Shape
s, etc).

    protected double[][]
    computeXYColors(int xRes, int yRes, int nLevels)
    Having the colors of the surface on the XY plane gives a lot of info in some surfaces
    protected void
    extractCountours(double[][] contours, double[][] matrix, int xSpan, int ySpan)
    A point belongs to the contour if it is bigger than anyone of the surrounding points of the Quantized matrix It is NOT part of the contour if it is equal (or smaller) to all the surrounding points
    protected void
    quantizeMatrix(double[][] matrix, double[] sortedLevels)
    Force the input matrix to have the minimum bigger value of the user provided sortedLevels list
    protected void
    quantizeMatrix(double[][] matrix, double min, double max, int n)
    Force the input matrix to have values rounded to one of the N steps in the range [min;max].
