Module nurb_curve 

Structs

NurbCurve

A NURBS curve whose control points live in D-dimensional homogeneous space.

Traits

HasConvexHull

Bridges NurbCurve<S, D>’s pair of concrete convex_hull()/size() impls (D=4 → ConvexHull<S,3>, D=3 → ConvexHull<S,2>) so code generic over D (e.g. curve_curve_intersect, curve_could_contain) can call them via a where NurbCurve<S, D>: HasConvexHull<S, C> bound — Rust’s stable const generics can’t express C = D - 1 directly in a single generic function.

ParameterRefinable

Bridges a NurbCurve<S, D>’s Cartesian evaluation (D = 4 -> 3-D points, D = 3 -> 2-D pcurve points) so NurbCurve::refine_parameter_at_point can be written once for both — stable Rust’s const generics cannot express C = D - 1 directly.

Functions

true_point_fractions

Where, within interval i of intervals between consecutive samples, a caller of interpolate_enclosing should locate its true points: these fractions of the way from one sample to the next.
