Detailed Description

A merge that can be applied to a T-tessellation.

A merge is the removal of a non-blocking segment. The two faces on both sides of the removed segment are merged.

A merge is represented by the (half)edge to be removed.

A merge has several effects on tessellation elements:

Two vertices are removed.
Two pairs of edges are merged.
Two faces are replaced by a single one.
A non-blocking segment is removed.
The status (blocking or not) of segments incident to the removed segment may change.
