Motivation
Two ways to get complex meshes
modeling & range scanning
Complex meshes challenge
1. Rendering performance
2. Transmission bandwidth
3. Storage capacities
43,000 faces 43,000 faces
Motivation cont
The practical problems:
Mesh simplification
Level-of-detail approximation(smoothly)
Progressive transmission
Mesh compression
Minimizing the storage space for a mesh
Selective refinement
Only in selected region, high detailed for a model is
required
13,000
1,000 200
Mesh simplification
The number of faces
are reduced while
minimally perturbing
the shape
