23. Modeling – Simplification
Surface Simplification Using Quadric Error Metric
Michael Garland and Paul S. Heckbert
ACM SIGGRAPH ‘97
Fast simplification using distance error metric
Estimate error between
The current model and
The simplified model after the next step

24. Modeling – Simplification
Progressive Meshes
Hugues Hoppe
ACM SIGGRAPH ‘96
Store the simplification order of sequence
Continuous LOD  Reduces popping effect
Included in DirectX
