Polyline.tangent_at

Polyline.tangent_at(t)

Tangent vector at a specific normalized parameter.

Parameters:

tfloat

The parameter value.

Returns:

compas.geometry.Vector

The tangent vector at the specified parameter.

Examples

>>> polyline = Polyline([[0.0, 0.0, 0.0], [1.0, 0.0, 0.0], [1.0, 1.0, 0.0]])
>>> print(polyline.tangent_at(0.75))
