Struct tray_rust::film::camera::Camera

pub struct Camera {
    pub active_at: usize,
    // some fields omitted
}

Our camera for the ray tracer, has a transformation to position it in world space

Fields

active_at: usize

The frame this camera becomes active on

Methods

impl Camera

pub fn new(
    cam_world: AnimatedTransform,
    fov: f32,
    dims: (usize, usize),
    shutter_size: f32,
    active_at: usize
) -> Camera

Create the camera with some orientation in the world specified by cam_world and a perspective projection with fov. The render target dimensions dims are needed to construct the raster -> camera transform animation is used to move the camera ote that this is specified in camera space where the camera is at the origin looking down the -z axis

pub fn animated_fov(
    cam_world: AnimatedTransform,
    fovs: Vec<f32>,
    fov_knots: Vec<f32>,
    fov_spline_degree: usize,
    dims: (usize, usize),
    shutter_size: f32,
    active_at: usize
) -> Camera

Create a camera with some orientation in the world specified by cam_world and an animated perspective projection with fov. The render target dimensions dims are needed to construct the raster -> camera transform animation is used to move the camera ote that this is specified in camera space where the camera is at the origin looking down the -z axis

pub fn update_frame(&mut self, start: f32, end: f32)

Update the camera's shutter open/close time for this new frame

pub fn shutter_time(&self) -> (f32, f32)

Get the time that the shutter opens and closes at

pub fn generate_ray(&self, px: &(f32, f32), time: f32) -> Ray

Generate a ray from the camera through the pixel px

Trait Implementations

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.

impl Debug for Camera

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.
