Definition
A mesh is a set of points (vertices) connected into polygons, usually triangles. Unlike a point cloud, it defines an explicit surface structure. For this, the connectivity (topology) between the points has to be defined.
Meshes are the standard representation in computer graphics. In 3D vision they are often the final output of a reconstruction pipeline, for example Poisson surface reconstruction turns oriented points into a watertight triangle mesh.
