Struct Ray3D 

pub struct Ray3D {
    pub origin: Vector3D,
    pub direction: Vector3D,
}

A 3D ray defined by an origin point and a direction vector.

Fields

origin: Vector3D

The origin point of the ray.

direction: Vector3D

The direction vector of the ray (should be normalized).

Implementations

impl Ray3D

Implements methods for Ray3D.

pub fn point_at(&self, t: f64) -> Vector3D

Returns the point on the ray at the given parameter value.

Arguments

• f64 - The parameter value (distance along the ray).

Returns

• Vector3D - The point at the given distance.

pub fn intersect_sphere(&self, sphere: Sphere) -> Option<f64>

Tests for intersection with a sphere, returning the nearest distance if hit.

Arguments

• Sphere - The sphere to test.

Returns

• Option<f64> - The distance to the intersection, or None.

pub fn intersect_plane(&self, plane: Plane) -> Option<f64>

Tests for intersection with a plane, returning the distance if hit.

Arguments

• Plane - The plane to test.

Returns

• Option<f64> - The distance to the intersection, or None.

pub fn intersect_aabb(&self, aabb: AABB3D) -> Option<f64>

Tests for intersection with an AABB, returning the nearest distance if hit.

Arguments

• AABB3D - The bounding box to test.

Returns

• Option<f64> - The distance to the intersection, or None.
