cachai.utilities.get_bezier_curve

cachai.utilities.get_bezier_curve(points, n=20)[source]

Generates a sequence of points along a Bézier curve.

Parameters

pointslist or array-like: List containing the control points. The control points must me tuple or array-like as (x,y). For quadratic Bézier curve 3 points are needed, for cubic Bézier curve 4 points are needed.
nint: Number of points to generate along the curve (default: 20).

Returns

numpy.ndarray : 1D array of points (x,y)

Examples

import cachai.utilities as chu

curve = chu.get_bezier_curve([(0, 0), (2, 3), (4, 1)], n=10)
