All Implemented Interfaces:

VolumeDataViewCombiner

public class ANDCombiner
extends BinOpCombiner

This Combiner performs an AND-like operation over each of the data sets at each vertex. If all of the sampled values at a particular vertex yield a relative high value, then the output color intensity is high. This Combiner requires a ColorLookupTable array of size one.

computeColors

public void computeColors(double[][] valuesArray,
                          ColorLookupTable[] colorTables,
                          float[] baseColor,

                          float[] outColors)

Description copied from class: AbstractVolumeDataViewCombiner

Computes colors given the specified inputs and modified outColors to hold the computed colors. Subclasses should override this method to implement thier combination schemes.

Specified by:

computeColors in interface VolumeDataViewCombiner

Overrides:

computeColors in class BinOpCombiner

Parameters:

valuesArray - should be in the format of [view index][vertex index]

colorTables - an array of ColorLookupTables, should be length one if needsManyColorTables() returns false, or the same length at the number of views in the valuesArray if needsManyColorTables() returns true

baseColor - the base color to be used in the blend function

function - the blend function to use to blend the base color with the mapped color from the ColorLookupTable(s).

prepData - the preprocessing data computed across each of the full sampled data sets

outColors - destination of computed colors, should be the same length as computeColorsSize(valuesArray)
