Finding geodesics on a mesh? What are some state of the art methods/algorithms to find geodesics on arbitrary manifold meshes?
There can be much dispute on which work is considered best or state-of-the-art. It will depend on your application. However, I'd like to recommend to give a look at this paper by Keenan Crane et al. It is impressive in terms of computational speed. Also, It is simple to implement.
