All Implemented Interfaces:

SafeDisposable

public class PoLinearDataMapping
extends PoDataMapping

Node class to define a linear data mapping. This node defines the current data mapping for all subsequent MeshViz representations which use it. There is no data mapping until a PoDataMapping node is traversed.

This node defines a linear association between colors, transparencies and floating-point values. In other words, this association is defined by 2 functions F(c,v) and F(c,t):

      F(c,v)(V) = C (with c being a color and v being a value).
      F(t,v)(V) = T (with t being a transparency and v being a value).

F(c,v) and F(t,v) are linear, so only two values (value1 and value2), two associated transparencies (transparency1,transparency2) and two associated colors (color1 and color2) define these functions. For a given value vi, its color ci is determined by linear interpolation between (value1,color1) and (value2,color2). Idem for the transparencies.
