Indexed mesh
Description
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 functionglDrawElements().
Finding neighbours is well defined (no floating point issues) but is still inconvenient.
- a list of vertices (each vertex stored once)
- a list triangles composed of vertex indices
