Description

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 tetrahedra element. Other optional child elements may store precalculated properties of this triangulation.

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

Note

Regina supports triangulations in many dimensions. See also the elements packet (2-dimensional triangulation), packet (4-dimensional triangulation), and packet (dim-dimensional triangulation).

Deprecated Data

The child turaevviro element is deprecated, and should not be used. As of Regina 5.0, this element will not be written, and will be ignored when reading older data files.

Parents

The following elements contain packet: packet, reginadata.
