NAME

       stl_convex - stl_convex prints whether an STL file is a convex polyhedron.

DESCRIPTION

       stl_convex prints whether an STL file is a convex polyhedron.

       usage: stl_convex [ -v ] [ <input file> ]

              Prints  whether  the  input  file  is  a  convex  polyhedron.  If  no input file is
              specified, data is read from stdin. If  -v  is  specified,  prints  out  the  Euler
              characteristic in addition to whether the mesh is convex.

       The  Euler  characteristic of a polyhedral surface is defined as V - E + F, where V is the
       number of vertices, E is the number of edges, and F is the number  of  faces.  All  convex
       polyhedra will have an Euler characteristic of 2.
