Detailed Description
Abstract base class for 2-D PDE-based iterative level set solver.
This class provides infrastructure for 2-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.
