Re: [Algorithms] How to pack a vertex

[Pierre T. <p.t...@wa...>]

By delta-encoding the error vector between that vertex position and a
predicted vertex position? ...which takes into account the nearby vertices
and the mesh connectivity.

Else simply quantize them relatively to a bounding box ? But one way or
another I think you need to use nearby vertices and some "global knowledge"
(opposed to "local") to reach the best compression ratios.

Lots of papers out there (Rossignac, wavelet stuff, etc)

Best way depends on what you're really trying to do.
