cee::vis::ScalarMapper

class ScalarMapper : public RefCountedObject 

Abstract base class for scalar mappers.

The scalar mapper offers two services:

Map from a scalar value (domain value) to a texture coordinate or a color
Create a texture from the scalar mapper that can be used for rendering and corresponds with the texture coordinates produced.
