1.Shape representations

The package shape provides a set of tools to compute with shape represented by semi-algebraic models, including

• Point sets

• Meshes

• Parametric curves

• Parametric surfaces

• Implicit curves

• Implicit surfaces

2.Algorithms

• Matrix representation for curves and surfaces

• Topology and arrangement of algebraic curves

• Topology of surfaces

• Intersection of parametric surfaces

• Auto-intersection of parametric surfaces
