### 3.3.1 Triangulations

To create a triangulation you must either

- Open a project
- Read an old triangulation stored in text format
- Execute a program which contains the keyword `buildmesh`
- Create one by hand drawing the boundary of Omega and activate the menu `Triangulate` (Macintosh only).

In integrated environments, once created, triangulations can be displayed, stored on disk in Gfem format or in text format or even a zoom of its graphic display can be stored in Postscript format (to include it in a TeX file for example).

Gfem stores for each vertex its number and boundary identification number and for each triangle its number and region identification number. Edges number are not stored, but can be recovered by program if needed.
