coolColorMap

public static java.awt.Color[] coolColorMap(int N)

Generates an array of N colors from the colormap. This is a decent colormap for surfaces.

coolColorMap

public static java.awt.Color[] coolColorMap(int N,
                            double minAlpha)

Generates an array of N colors from the colormap. The alpha value of each color increases proportionally from the given minimum value up to a maximum value of 1.0. This is a decent colormap for surfaces.

coolColorMap

public static java.awt.Color[] coolColorMap(int N,
                            double minAlpha,
                            double maxAlpha)

Generates an array of N colors from the colormap. The alpha value of each color increases proportionally from the given minimum value up to a maximum value of 1.0. This is a decent colormap for surfaces.

grayColorMap

public static java.awt.Color[] grayColorMap(int N)

Generates an array of N colors from the gray colormap. This is a decent colormap for surfaces.

luminance

public static DblMatrix luminance(java.awt.Color color)

Returns the approximate luminance of a Color.

setColorMap

public void setColorMap(java.awt.Color[] vals)

setColorMap

public void setColorMap(java.awt.Color[] vals,
               DblMatrix data)

getColorFor

public java.awt.Color getColorFor(DblMatrix[] DATA)

Colormapping to given data. The DblMatrix[] input is assumed to be the data of the linesegment or of the grid patch coordinates for surfaces.

Specified by:

getColorFor in interface ColorMapper
