# 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

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

 from_data Construct a curve from its data representation. locus Compute the locus of all points on the curve. point Compute a point on the curve. tangent Compute the tangent vector at a point on the curve. transform Transform this curve.

Inherited Methods

 copy Make an independent copy of the data object. from_json Construct an object from serialized data contained in a JSON file. from_jsonstring Construct an object from serialized data contained in a JSON string. to_data Convert an object to its native data representation. to_json Serialize the data representation of an object to a JSON file. to_jsonstring Serialize the data representation of an object to a JSON string. transformed Returns a transformed copy of this geometry. validate_data Validate the object's data against its data schema. validate_json Validate the object's data against its json schema.
