pub fn locate3(
curve: &Curve3,
point: Point3,
tolerance: Tolerance,
) -> GeomResult<Scalar>Expand description
Parameter of a point on a 3D curve, iterating where no closed form
exists: invert3 first, and for a B-spline the nearest of 64 samples
per span refined by Newton on |C(t) - p|^2. The answer must reproduce
the point within tolerance, as invert3’s must.
§Errors
The point is not on the curve, or the family cannot be evaluated.
