Morse Theory for Implicit Surface Modeling

Mathematical Visualization, H-C Hege and K. Polthier, Eds., Springer-Verlag, Oct. 1998, pp. 257-268

Morse theory describes the relationship between a function's critical points and the homotopy type of the function's domain. The theorems of Morse theory were developed speci cally for functions on a manifold. This work adapts these theorems for use with parameterized families of implicit surfaces in computer graphics. The result is a theoretical basis for the determination of the global topology of an implicit surface, and supports the interactive modeling of implicit surfaces by direct manipulation of a topologically-correct triangulated representation
