Computing geodesics on triangular meshes
TL;DR: A new algorithm to compute a geodesic path over a triangulated surface based on Sethian's Fast Marching Method and Polthier's straightest geodesics theory is presented, which can handle both convex and non-convex surfaces.

SMI 2011: Full Paper: Interactive 3D caricature from harmonic exaggeration
TL;DR: This work introduces a caricature tool that interactively emphasizes the differences between two three-dimensional meshes, represented in the manifold harmonic basis of the shape to be caricatured, providing intrinsic controls on the deformation and its scales.

TL;DR: An iterative process is generated based on Sethian's fast marching method and Polthier's straightest geodesics theory to obtain a good discrete geodesic approximation that can handle convex and nonconvex surfaces as well.
