Orbifolds for Geometry Processing
8. Mai 2017 | Kolloquium
Tuttes graph drawing algorithm is the basis of the most popular techniques for embedding planar graphs in the plane as it guarantees validity, is simple to compute, and minimizes a natural distortion energy. In this talk we show how Tutte's algorithm can be generalized to handle a rich set of target domains called Orbifolds. Orbifolds are intriguing simple surfaces generated by symmetry groups acting on the two-dimensional Euclidean, hyperbolic and spherical domains. We will demonstrate how these Tutte-orbifold embedding techniques facilitate geometry processing tasks such as approximation of conformal maps, surface-to-surface mapping, and deep-learning on surfaces. This is a joint work with Noam Aigerman, Haggai Maron and others Ill mention in the talk.
