Fair morse functions for extracting the topological structure of a surface mesh

X Ni, M Garland, JC Hart - ACM Transactions on Graphics (TOG), 2004 - dl.acm.org
Morse theory reveals the topological structure of a shape based on the critical points of a
real function over the shape. A poor choice of this real function can lead to a complex …
