Detailed Description

Abstract base class for 3-D PDE-based iterative level set solver.

This class provides infrastructure for 3-D PDE-based iterative level set solver. Internally, the class implements upwind-style wave propagation and the inheriting classes must provide a way to compute the derivatives for given grid points.
