Class ColorMap.Hue<T>

Object

ColorMap<T>

ColorMap.Gradient<T>

ColorMap.Gradient1D<T>

Hue<T>

Type Parameters:

T - type of color object: String or MeshLambertMaterial for GWT and Color for JRE

Direct Known Subclasses:

ColorMap3D.Hue, ColorMapCSS.Hue

Enclosing class:

ColorMap<T>

public abstract static class ColorMap.Hue<T>
extends ColorMap.Gradient1D<T>

Color gradient following the hue.

The actual data-to-color translation is performed in the super class.

Constructor Details

Hue

protected Hue(double start,
 double end,
 boolean ascending,
 T[] colors)

Construct a new Hue color map, starting at a hue of 0.0 (red) up to hue 1.0 (red, again) and interpolate with steps-1 intermediate colors. The resulting gradient spans steps+1 colors. The default range for mapping data values onto the color gradient is [0.0, 1.0].

Important: Cannot allocate the array for the gradient. Must be handled by subclasses.

Parameters:

start - the starting hue

end - the ending hue

ascending - the flag to indicate if hue is increasing

colors - the array to store the hue colors

• ColorMap.Gradient1D.setRange(double, double)
• setHueRange(double, double)

Method Details

setHueRange

public void setHueRange(double start,
 double end)

Set hues ranging from start to end in increasing colors. Notes:

1. If end≤start the colors warp around through red.
2. The saturation and brightness of the gradient are both maximal.

Parameters:

start - the starting hue

end - the ending hue

setHueRange

public void setHueRange(double start,
 double end,
 boolean ascending)

Set the hues ranging from start to end in increasing or decreasing colors. Notes:

1. If end≤start the colors warp around through red.
2. If ascending == false the hue is interpolated in reverse.
3. The saturation and brightness of the gradient are both maximal.

Parameters:

start - the starting hue

end - the ending hue

ascending - true to increment the hue value
