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).
There are two ways to express F(c,v)(V):
There are as well, two ways to express F(t,v)(V)

Reimplemented from PoDataMapping.
SoMFColor PoNonLinearDataMapping2::color |
Defines the list of colors for the data mapping.
The number of colors must be >= the number of values + 1 if the type is NON_LINEAR_PER_LEVEL and >= the number of values otherwise.

SoMFFloat PoNonLinearDataMapping2::transparency |
Defines the list of transparencies for the data mapping.
To be taken into account the number of transparencies must be equal to the number of colors, otherwise transparencies are ignored.
