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.
