Class ContourPlot.BarycentricGradientPaint

  • All Implemented Interfaces:
    java.awt.Paint, java.awt.Transparency
    Enclosing class:
    ContourPlot
    public class ContourPlot.BarycentricGradientPaint
extends java.lang.Object
implements java.awt.Paint
    The BarycentricGradientPaint class provides a way to fill a Shape with a triangular color gradient. Colors are specified for the vertices of a triangle and interpolated within the triangle according to barycentric coordinates. Only areas of the filled shape that are intersecting with the triangle of this paint are colored.

    This paint supports the ANTIALIASING rendering hint (RenderingHints) using a 4x multisampling approach. When enabled, the edges of the triangle will appear anti-aliased. It is recommended to disable AA when filling a triangle mesh (where triangles are adjacent), since otherwise triangle edges become visible.

    Note that it is not necessary to use a triangular Shape to render a triangle. Instead a rectangle can be used as well, since only the intersecting area will be filled.
