Struct RaySurface 

pub struct RaySurface { /* private fields */ }

A NURBS surface made ready for ray crossings.

It holds the surface’s Bezier patches, each a grid of homogeneous control points. A surface whose weights are all positive lies in the hull of each patch’s control points, which the search relies on to pass over the patches a ray misses.

Implementations

impl RaySurface

pub fn new(surface: &NurbsSurface) -> Option<Self>

surface made ready, or None when a weight is not positive, a knot vector is not clamped, or the surface cannot be cut into Bezier patches.

pub const fn surface(&self) -> &NurbsSurface

The surface.

pub fn hits(&self, origin: Point3, dir: Vec3, reach: f64) -> RayHits

Every point where the line through origin along dir meets the surface no farther than reach behind origin, with t measured along dir made unit. A hit within reach of another is the same hit.
