      getMaxEdgeCount in interface Mesh
      Returns:
      maximum number of edges

      Description copied from interface: Mesh
      Gets the normal vector of normal index. The normal vector is not necessarily normalized.
      Specified by:
      getNormal in interface Mesh
      Parameters:
      index - normal number
      out - normal vector will be placed in here
