A fundamental problem when representing or analyzing object is the following: given a set of  points, generally produced by scanning some object (i.e. in applications such as motion  capture, facial recognition, medical imaging, etc.), reconstruct a triangulation on these points which accurately represents the original object.  We will survey classical results and algorithms from this area, focusing especially on the crust and powercrust algorithms, which were some of the first to give provable guarantees on the quality of the reconstruction, both from a topological and a geometric standpoint.
