Acknowledgments

I thank Mihai Popovici and Biondo Biondi for drawing my attention to the fast marching level set method. Discussions with Bill Symes, Dan Kosloff, and Tariq Alkhalifah were crucial for developing a general understanding of the method. Jamie Sethian kindly responded to more specific questions. The conforming triangulation program was developed at the suggestion of Leonidas Guibas as a research project for his Geometrical Algorithms class at Stanford.
