> <\body> \; A mesh is a collection of points, with connectivity information. Usually the points are stored \ as a sequence of coordinates. The connectivity informations can correspond to edges or faces. They are described as sets of indices of the points which form the edge or \ the face. For triangular meshes, where all the faces are triangles, a triangle is stored as a triple of indices. <\with|par-mode|center> |mesh_polygirl.axl> \; Here is the file format used in to store surface meshes. <\cpp-code> \surface type="mesh" "polygirl" \ \ \off\ ... \/off\ \/surface\ (blue parts are optional). \ \ \; <\initial> <\collection>
