Function project_curve3

pub fn project_curve3(
    curve: &BSplineCurve<DVec3>,
    target: DVec3,
    options: ProjectionOptions,
) -> Result<CurveProjection3, GeomError>

Find the best spatial-curve projection candidate within explicit budgets.

Every active knot span and both domain endpoints are seeded. The result is not a certified global minimum; inspect its status and distance.
