28 Oct 2009	Helen Chen	This set of MATLAB files implements Level Set Methods and follows Osher and Fedkiw's book. A combination of curvature-based forces, vector field-based forces and forces in the normal direction can be used. * This toolbox currently implements only a 2-D interface (curve) evolution. Extending to 3-D interface (surface) evolution is trivial because of its modular structure based on 1-D functions (I'll do this soon). * 1st, 2nd and 3rd order accurate Essentially Non-Oscillatory (ENO) and 5th order accurate Weighted ENO (WENO) are supported throughout the toolbox for derivative calculations. * A function for re-initialization of a signed distance function is provided (reinit_SD). * A high-level function (evolve2D) is provided that can utilize any combination of: 1) a force in the normal direction to the curve, 2) a curvature-based force, 3) evolution under the influence of an external vector field.
