Incorporating deformations into a modeling system
“Free-form deformations” for arbitrary warping of space
- Use a 3-D lattice of control points to define Bezier cubics:
(x’,y’,z’) are piecewise cubic functions of (x,y,z)
- Widely used in commercial animation systems
Physically based deformations
- Based on material properties
- reminiscent of finite element analysis
