       This manual page documents briefly the happrox command.

       happrox  -  returns  a  simplified  triangulation  of  a set of points using algorithm III of Garland and
       Heckbert (1995).

       This program follow the usual GNU command line syntax, with long options starting with two dashes  (`-').
       A summary of options is included below.

       -nN, --number=N
              Stop the refinement process if the number of vertices is larger than N.

       -cC, --cost=C
              Stop the refinement process if the cost of insertion of a vertex is smaller than C.

       -f, --flat
              Input is a flat file with three x,y,z columns (default is PGM file).

       -rZ, --relative=Z
              Use relative height cost for all heights larger than Z.

       -k, --keep
              Keep enclosing triangle.

       -C, --closed
              Close the surface.

       -l, --log
              Log evolution of cost.

       -v, --verbose
              Display surface statistics.

       -h, --help
              Display the help and exit.
