Description

 -p

Triangulates a Planar Straight Line Graph (.poly file).

 -r

Refines a previously generated mesh.

 -q

Quality mesh generation.  A minimum angle may be specified.

 -a

Applies a maximum triangle area constraint.

 -u

Applies a user-defined triangle constraint.

 -A

Applies attributes to identify triangles in certain regions.

 -c

Encloses the convex hull with segments.

 -w

Weighted Delaunay triangulation.

 -W

Regular triangulation (lower hull of a height field).

 -j

Jettison unused vertices from output .node file.

 -e

Generates an edge list.

 -v

Generates a Voronoi diagram.

 -n

Generates a list of triangle neighbors.

 -g

Generates an .off file for Geomview.

 -B

Suppresses output of boundary information.

 -P

Suppresses output of .poly file.

 -N

Suppresses output of .node file.

 -E

Suppresses output of .ele file.

 -I

Suppresses mesh iteration numbers.

 -O

Ignores holes in .poly file.

 -X

Suppresses use of exact arithmetic.

 -z

Numbers all items starting from zero (rather than one).

 -o2

Generates second-order subparametric elements.

 -Y

Suppresses boundary segment splitting.

 -S

Specifies maximum number of added Steiner points.

 -L

Uses equatorial circles, not equatorial lenses.

 -i

Uses incremental method, rather than divide-and-conquer.

 -F

Uses Fortune's sweepline algorithm, rather than d-and-c.

 -l

Uses vertical cuts only, rather than alternating cuts.

 -s

Force segments into mesh by splitting (instead of using CDT).

 -L

Uses Ruppert's diametral spheres, not diametral lenses.

 -C

Check consistency of final mesh.

 -Q

Quiet:  No terminal output except errors.

 -V

Verbose:  Detailed information on what I'm doing.

 -h

Help:  Detailed instructions for Triangle.
