Modeling Complex Shapes
We want to build models of very complicated objects
An equation for a sphere is possible, but how about an equation for a telephone, or a face, or a cloud?
Complexity is achieved using simple pieces
- The pieces could be polygons, parametric surfaces, or implicit surfaces
Requirements
- Model anything with arbitrary precision (in principle)
- Easy to build and modify
- Efficient computations (for rendering, collisions, etc.)
- Easy to implement (a minor consideration...)
