Bezier
- class compas.geometry.Bezier(points)[source]
Bases:
Primitive
A Bezier curve is defined by control points and a degree.
A Bezier curve of degree n is a linear combination of
n + 1
Bernstein basis polynomials of degree n.- Parameters
points (sequence[point]) – A sequence of control points, represented by their location in 3D space.
- Attributes
points (list[
compas.geometry.Point
]) – The control points.degree (int, read-only) – The degree of the curve.
Examples
>>> curve = Bezier([[0.0, 0.0, 0.0], [0.5, 1.0, 0.0], [1.0, 0.0, 0.0]]) >>> curve.degree 2
Methods
