## Description

In ®ina; 6.0.1 and earlier, the &xml-packet; element was used to store every packet in the entire packet tree that makes up a ®ina; data file. This page describes how the &xml-packet; element was structured when storing a 3-dimensional triangulation. Since ®ina; 7.0, each packet type has its own &xml; element; in particular, all triangulations are now stored using the &xml-tri; element.

This type of triangulation packet stores a 3-dimensional triangulation (typically of a 3-manifold).

The tetrahedra forming this triangulation and their corresponding face gluings are specified by the child &xml-tetrahedra; element. Other optional child elements may store precalculated properties of this triangulation.

The roles played by the child &xml-tag; and &xml-packet; elements are described in the general &xml-packet; element documentation.

®ina; supports triangulations in many dimensions. See also the elements &xml-packet-dim2triangulation;, &xml-packet-dim4triangulation;, and &xml-packet-triangulation;.
