OCCNurbsCurve.closest_point

OCCNurbsCurve.closest_point(point, return_parameter=False)

Compute the closest point on the curve to a given point. If an orthogonal projection is not possible, the start or end point is returned, whichever is closer.

Parameters:

pointPoint

The point to project to the curve.

return_parameterbool, optional

If True, return the curve parameter in addition to the closest point.

Returns:

Point | tuple[Point, float]

If return_parameter is False, the nearest point on the curve. If return_parameter is True, the nearest point on the curve and the corresponding parameter.
