Detailed Description

MeshViz Abstract class for data mapping.

Data mapping defines an association between colors, transparencies and floating-point values. Giving transparencies is not compulsory. When they are not given, they are supposed to be equal to 0 , i.e. each color is opaque.

Whichever data mapping, two threshold values can be defined, threshold_min and threshold_max. One color (cmin) and one transparency (transp_min) are associated to threshold_min . As well, cmax and transp_max are associated to threshold_max. For a given value vi <= threshold_min, the associated color ci is cmin and the associated transparency ti is transp_min. As well, for a given value vi >= threshold_max, the associated color ci is cmax and the associated transparency ti is transp_max.

By default min and max thresholds are disabled, threshold_min = 0 and threshold_max = 1 and no color is associated to threshold_min and threshold_max. Each part of primitive of which transparency is greater or equal 0.95 is deleted. This default value can be changed by the method setTransparencyValueDeletedParts().
