[name]
Represents a lookup table for colormaps. It is used to determine the color values from a range of data values.
Example
var lut = new THREE.Lut( "rainbow", 512 );
var data = [0, 10.1, 4.2, 3.4, 63, 28];
lut.setMax(63);
color = lut.getColor(10);
Constructor
[name]( colormap, numberOfColors )
colormap - optional argument that sets a colormap from prefefined colormaps. Available colormaps are : "rainbow", "cooltowarm", "blackbody".
numberOfColors - optional argument that sets the number of colors used to represent the data array.
Properties
.[page:Float minV]
The minimum value to be represented with the lookup table. Default is 0.
.[page:Float maxV]
The maximum value to be represented with the lookup table. Default is 1.
Methods
.copy( [page:Lut lut] ) [page:Lut this]
color — Lut to copy.
Copies given lut.
.setminV( [page:Float minV] ) [page:Lut this]
minV — The minimum value to be represented with the lookup table.
Sets this Lut with the minimum value to be represented.
.setmaxV( [page:Float maxV] ) [page:Lut this]
maxV — The maximum value to be represented with the lookup table.
Sets this Lut with the maximum value to be represented.
.changeNumberOfColors( [page:Float numberOfColors] ) [page:Lut this]
numberOfColors — The number of colors to be used to represent the data array.
Sets this Lut with the number of colors to be used.
.changeColorMap( [page:Float colorMap] ) [page:Lut this]
colorMap — The name of the color map to be used to represent the data array.
Sets this Lut with the colormap to be used.
.addColorMap( colorMapName, arrayOfColors ) [page:Lut this]
Insert a new color map into the set of available color maps.
.getColor( value ) [page:Lut this]
value -- the data value to be displayed as a color.
Returns a Three.Color.
