Struct Ray 

pub struct Ray {
    pub origin: [f32; 3],
    pub dir: [f32; 3],
}

A 3D ray with origin and (ideally normalized) direction.

Fields

origin: [f32; 3]

Ray origin in world space.

dir: [f32; 3]

Ray direction (should be normalized).

Implementations

impl Ray

pub fn new(origin: [f32; 3], dir: [f32; 3]) -> NerfResult<Self>

Create a ray with the given origin and direction (not normalized).

Errors

Returns ZeroRayDirection if |dir| < 1e-8.

pub fn normalized(origin: [f32; 3], dir: [f32; 3]) -> NerfResult<Self>

Create a ray with automatically normalized direction.

Errors

Returns ZeroRayDirection if |dir| < 1e-8.

pub fn at(&self, t: f32) -> [f32; 3]

Evaluate the point along the ray at parameter t: origin + t * dir.
