Detailed Description
Node class to define a non 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 non 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 given by the user. If they are not given by the user, default one are used. The default F(c,v) computes a linear data mapping between black and white. The default F(c,t) returns always 0.
