NAME

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

SYNOPSIS

       happrox [OPTIONS] < [input.pgm|input] > output.gts

DESCRIPTION

       This manual page documents briefly the happrox command.

OPTIONS

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

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

       -c C, --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).

       -r Z, --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.
