[−][src]Struct raytracer::Camera

pub struct Camera { /* fields omitted */ }

This struct allows to position viewer in the scene.

Methods

impl Camera[src]

pub fn new(
    look_from: Vec3,
    look_at: Vec3,
    up: Vec3,
    fov: f32,
    aspect_ratio: f32
) -> Camera[src]

Camera's constructor.

  • look_from - Camera's position.
  • look_at - The point camera is focusing on.
  • up - Vec3 that describes "up" direction in the world. Generally (0, 1, 0).
  • fov - Vertical field of view in degrees.
  • aspect_ratio - Aspect ratio of image's dimensions: width / height.

pub fn ray(&self, s: f32, t: f32) -> Ray[src]

Emits a Ray for given pixel on virtual camera's canvas.

  • s - Horizontal coordinate on canvas. Must be a value in range [0; 1].
  • t - Vertical coordinate on canvas. Must be a value in range [0; 1].
