DensityBase Class Reference

#include <densitybase.h>

Detailed Description

This class allows changing the representation of density isosurfaces.

It allows adding/deleting and changing the visual representation of isodensity surfaces. Up to 2 source densities can be loaded and combined (added/substracted). It provides the functionality for the DensityWidget class (base class).
