Struct Ray 

pub struct Ray { /* private fields */ }

Finite world/local ray with a unit direction.

Implementations

impl Ray

pub fn new(origin: Vec3, direction: Vec3) -> Option<Self>

Normalizes a nonzero direction; invalid data returns None.

pub fn origin(self) -> Vec3

Ray start point.

pub fn direction(self) -> Vec3

Unit direction along increasing distance.

pub fn point_at(self, distance: f32) -> Vec3

Point at a signed distance from the origin; negative distances go backward.

pub fn transformed(self, matrix: Mat4) -> Option<Self>

Transforms the origin and direction, then renormalizes the direction. Only affine matrices are accepted; singular transforms may collapse the ray.

pub fn plane_distance(self, point: Vec3, normal: Vec3) -> Option<f32>

Forward distance to a plane represented by a point and any nonzero normal. Parallel, backward, non-finite or degenerate intersections return None.

pub fn sphere_distance(self, center: Vec3, radius: f32) -> Option<f32>

First forward intersection with a finite positive-radius sphere. Origins inside/on the sphere return zero, matching AABB query semantics. Entirely backward intersections return None instead of a false zero hit.
