Figure 5From: An ordered topological representation of 3D triangular mesh facial surface: concept and applicationsGeodesic path computation: (a) Example of a geodesic path computation. The facet spiral is expanded from a source facet on the nose tip to the destination facet, then the geodesic path is extracted by tracing back the source facet. (b) Examples of geodesic paths between the nose tip and facets on a periphery ring.Back to article page
