Struct SurfaceBoundOracle 

pub struct SurfaceBoundOracle<'a> { /* private fields */ }

Derivative bounds of one surface, prepared once for many boxes.

A B-spline surface’s derivative control nets are built on construction, so each Self::bounds call only scans the window of the box.

Implementations

impl SurfaceBoundOracle<'_>

pub fn separation( &self, u: (Scalar, Scalar), v: (Scalar, Scalar), ) -> Option<ParameterSeparation>

The certified separation over the box [u.0, u.1] x [v.0, v.1], or None where it cannot be shown positive: a pole, an apex, a fold, a box too wide, or a B-spline crease or edge inside it (!smooth).

impl<'a> SurfaceBoundOracle<'a>

pub fn new(surface: &'a Surface) -> Option<Self>

Prepare the bounds of surface, or None for a family (or data) this module cannot bound.

pub fn for_carrier(carrier: &'a Carrier) -> Option<Self>

Prepare the bounds of the surface a curve lies on (ADR 0077), or None for non-finite data or a malformed spline net.

pub fn bounds( &self, u: (Scalar, Scalar), v: (Scalar, Scalar), ) -> Option<SurfaceBounds>

Bounds over the box [u.0, u.1] x [v.0, v.1]; None where the surface is not defined (a cone past its apex) or the data is not finite.
