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

.SH SYNOPSIS
.B happrox
.RI [\| OPTIONS \|]\ <\ [\| input.pgm | input \|]\ >\  output.gts

.SH DESCRIPTION
This manual page documents briefly the 
.B happrox
command.

.SH OPTIONS
This program follow the usual GNU command line syntax, with long
options starting with two dashes (`-').
A summary of options is included below.
.TP
.BI \-n\  N\fR,\  \-\-number= N
Stop the refinement process if the number of vertices is larger than \fIN\fR.
.TP
.BI \-c\  C\fR,\  \-\-cost= C
Stop the refinement process if the cost of insertion of a vertex is smaller than \fIC\fR.
.TP
.BR \-f ,\  \-\-flat
Input is a flat file with three x,y,z columns (default is PGM file).
.TP
.BI \-r\  Z\fR,\  \-\-relative= Z
Use relative height cost for all heights larger than \fIZ\fR.
.TP
.BR \-k ,\  \-\-keep
Keep enclosing triangle.
.TP
.BR \-C ,\  \-\-closed
Close the surface.
.TP
