pub struct Camera {
    pub origin: [f32; 3],
    /* private fields */
}

A simple pinhole camera.

Fields

origin: [f32; 3]

Camera origin.

Implementations

impl Camera

pub fn new( look_from: [f32; 3], look_at: [f32; 3], vup: [f32; 3], vfov: f32, aspect_ratio: f32, aperture: f32, focus_dist: f32, ) -> Self

Construct a camera.

• look_from — eye position
• look_at — target position
• vup — world up vector
• vfov — vertical field of view in degrees
• aspect_ratio — image width / height
• aperture — lens aperture (0 = pinhole)
• focus_dist — focus distance

pub fn get_ray(&self, s: f32, t: f32, rng: &mut impl Rng) -> Ray

Generate a ray for pixel coordinates (s, t) in [0,1]×[0,1].
