Description
In Regina 6.0.1 and earlier, the packet element was used
to store every packet in the entire packet tree that makes up a
Regina data file.
This page describes how the packet element was structured when
storing a 3-dimensional triangulation.
Since Regina 7.0, each packet type has its own XML element;
in particular, all triangulations are now stored using the
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 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).
Children
The following elements occur in packet for
a 3-dimensional triangulation packet:
compressingdisc, fundgroup, H1, H1Bdry, H1Rel, H2, haken, irreducible, packet, splitsfce, solidtorus, tag, tetrahedra, threeball, threesphere, txi, zeroeff.
