Returns:

Type:: CubicBezierTuple

length(samplesopt, extra_lengthopt) → {number}

Returns an approximation of the length of the cubic bezier curve, based on sampling points along the curve and an optional extra length to add.

Parameters:

Name	Type	Attributes	Description
`samples`	number \| null	<optional>	The number of samples to take along the curve.
`extra_length`	number \| null	<optional>	An optional extra length to add to the approximation.

Returns:

Type:: number

point_at(t) → {Point2D}

Returns the point on the cubic bezier curve at a given t value.

Parameters:

Name	Type	Description
`t`	number	The t value to evaluate the polynomial at. A number between 0 and 1.

Source: pkg/index.js, line 1721

Returns:

The point on the cubic bezier curve when the polynomial is evaluated at the given t value.

Type:: Point2D

(static) from_line(p1, p2) → {CubicBezierTuple}
