An *indexed
mesh* stores:

Note this separately stores the geometry and the topology.

Indexed meshes are well suited to rendering using modern graphics hardware. In particular, they can be rendered simply with the function*glDrawElements().*

Finding neighbours is well defined (no
floating point issues) but is still inconvenient.
