## Triangle Strip (trnglStr)

## Description

A triangle strip which is a set of triangles where each triangle shares
two vertices with the preceding triangle. The first three indices define a
triangle and then each additional index defines another triangle by using
the two preceding indices.

## Conventions

By convention the first triangle is right handed and then the handedness
flips for each successive triangle. Useful because triangle strips are
much faster to render on some architectures.
