Mesh Compression

Goals of mesh compression:

• minimize the storage requirements
• minimize the streaming size

Miscellaneous:

• Mesh size is measured in total number of bits or bits per vertex
• Geometry and topology are compressed separately and completely orthogonal

Topology compression

Shared vertex triangle lists

Triangle strips/Triangle trees

Valence-driven topology compression

Touma/Gotsman

Alliez/Desbrun

Geometry compression

Predecessor rule

Parallelogram rule
