Struct rtow::camera::Camera

pub struct Camera { /* fields omitted */ }

A camera represented as a single 3D point and a rectangular sensor. The sensor is identified by its lower left corner and two directional vectors (one horizontal and one vertical).

Methods

impl Camera

pub fn new(vert_fov: f64, aspect_ratio: f64) -> Camera

Creates a new camera centered in (0, 0, 0). The sensor is constructed based on the desired field of view and aspect ratio.

pub fn get_ray(&self, u: f64, v: f64) -> Ray

Creates a ray which runs from the camera center towards (and through) the screen. The values u and v provide the exact direction:

• Use (0.0, 0.0) for obtaining a ray that passes through the lower left corner of the sensor.
• Use (1.0, 1.0) for obtaining a ray that passes through the upper right corner of the sensor.
• Use anything in between for obtaining an arbitrary ray.

Trait Implementations

impl Copy for Camera

impl Clone for Camera

fn clone(&self) -> Camera

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
