Approaches Geometric Physical Hybrid Advantages/Disadvantages of above Approaches
6
Geometric Weil (1986) - Curve fitting, subdivision, relaxation Agui (1990) - Polygonization, relaxation Hinds (1990-92) - 3D interaction, interpolation Ng (1995) - Mapping
7
Physical Feyman (1986) - Energy minimization, Multigrid method Ng (1995) - extension of Feyman’s work Thalmann (1991-95) - Deformable model, Newtonian dynamics Breen (1992-94) - Energy minimization, Elasticity theory Baraff/Witkin (1998) - Implicit Integration
8
Thalmann Contribution Tailor approach to cloth visualization Focus on managing interaction between the garment and the body
