# delaunay(1)

constructs the constrained Delaunay triangulation of the input

## NAME

delaunay - constructs the constrained Delaunay triangulation of the input

## SYNOPSIS

**delaunay** \[*OPTIONS*\] \< *file.gts*

## DESCRIPTION

This manual page documents briefly the **delaunay** command. This command constructs the constrained Delaunay triangulation of the input

## OPTIONS

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

- **-b**, **--hull**

  Do not keep convex hull.

- **-e**, **--noconst**

  Do not add constrained edges.

- **-S**, **--split**

  Split constraints (experimental).

- **-H**, **--holes**

  Remove holes from the triangulation.

- **-d**, **--duplicates**

  Remove duplicate vertices.

- **-r**, **--randomize**

  Shuffle input vertex list.

- **-c**, **--check**

  Check Delaunay property.

- **-f** *FNAME,* **--files=***FNAME*

  Generate evolution files.

- **-o**, **--conform**

  Generate conforming triangulation.

- **-s** *N,* **--steiner=***N*

  Maximum number of Steiner points for conforming triangulation (default is no limit).

- **-q** *Q,* **--quality=***Q*

  Set the minimum acceptable face quality.

- **-a** *A,* **--area=***A*

  Set the maximum acceptable face area.

- **-v**, **--verbose**

  Print statistics about the triangulation.

- **-h**, **--help**

  Display the help and exit.
