三维的网格模型，期间任意两个点的测地距离指的是这两个点的最短路径，三维网格模型中任何两个点之间的最短路径。-Three-dimensional mesh model, any two points during the geodesic distance refers to the shortest path of these two points, 3D mesh model in any shortest path between two points.

Abstract—Recently, a 3D face recognition approach based on geometric invariant signatures, has been proposed. The key idea of the algorithm is a representation of the facial surface, invariant to isometric deformations, such as those result
