This paper describes the eccentricity, amplitude, phase shift, angular momentum, polarization, radial path, and orbital ...

Functions and modules that provide shortcuts for translation, rotation and mirror operations. Also provided are skew and frame_map which remaps the coordinate axes. The shortcuts can act on geometry, ...

Path A series of points joined by straight line segements. Bezier Curve A polynomial curve defined by a list of control points. The curve starts at the first control point and ends at the last one.
