Struct Lens 

pub struct Lens {
    pub aperture: f32,
    pub focal_depth: f32,
    pub max_coc: f32,
}

A lens: the CPU half of coc() in CAMERA_WGSL, with its inputs made safe once.

Fields

aperture: f32

Aperture in pixels, finite and non-negative.

focal_depth: f32

The focal plane’s view depth.

max_coc: f32

The largest circle of confusion drawn, in pixels — the tier’s cap.

Implementations

impl Lens

pub fn new(aperture: f32, focal_depth: f32, max_coc: f32) -> Self

A lens with aperture and max_coc held finite and non-negative.

pub fn coc(&self, depth: f32) -> f32

The circle of confusion at view depth depth, as a radius in pixels. Mirrors coc() in CAMERA_WGSL, term for term.

Trait Implementations

impl Clone for Lens

fn clone(&self) -> Lens

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Lens

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

Formats the value using the given formatter.

impl PartialEq for Lens

fn eq(&self, other: &Lens) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Lens
