Function project_surface

pub fn project_surface(
    surface: &BSplineSurface,
    target: DVec3,
    options: ProjectionOptions,
) -> Result<SurfaceProjection, GeomError>

Find the best tensor-product surface projection candidate within budgets.

The Cartesian product of active U/V knot-span seeds is refined with the exact squared-distance Hessian. The result is not a certified global minimum.
