@inproceedings{3556, abstract = {We define the Morse-Smale complex of a Morse function over a 3-manifold as the overlay of the descending and as- cending manifolds of all critical points. In the generic case, its 3-dimensional cells are shaped like crystals and are sepa- rated by quadrangular faces. In this paper, we give a combi- natorial algorithm for constructing such complexes for piece- wise linear data.}, author = {Herbert Edelsbrunner and Harer, John and Natarajan, Vijay and Pascucci, Valerio}, pages = {361 -- 370}, publisher = {ACM}, title = {{Morse-Smale complexes for piecewise linear 3-manifolds}}, doi = {10.1145/777792.777846}, year = {2003}, }
