## Package math.geom2d.circulinear Description

Definition of circulinear shapes and some implementations.

Circulinear shapes are composed only of pieces of lines and circles: circle arcs, line segments, rays... They have many interests:

- their length can be computed easily (if they are bounded)
- they can be transformed using
`circle inversion`

- they can be used to represent
**exactly**(i.e. without polygonal approximation) the buffer of a circulinear shape.
