Struct CameraUniform 

#[repr(C)]
pub struct CameraUniform {
    pub view_proj: [[f32; 4]; 4],
    pub viewport: [f32; 4],
    pub lens: [f32; 4],
}

The Camera uniform CAMERA_WGSL declares, as it is uploaded.

Field order is the WGSL struct’s, and both are vec4-aligned, so the Rust layout is the uniform layout with no padding to keep in step.

Fields

view_proj: [[f32; 4]; 4]

CameraView::view_proj.

viewport: [f32; 4]

[target width px, target height px, reference depth, volume's nearest view depth].

lens: [f32; 4]

[aperture px, focal depth, max circle of confusion px, volume's depth span].

Implementations

impl CameraUniform

pub fn new(view: &CameraView, width: u32, height: u32, lens: Lens) -> Self

The uniform for view on a width x height target through lens, with pixel widths stated at the lens’s focal plane. The volume is unset, so volume_depth() in CAMERA_WGSL reads 0 everywhere until with_volume names one.

pub fn with_volume(self, near_extent: f32, span: f32) -> Self

This uniform with the scene’s volume spanning view depths near_extent to near_extent + span: the 0-nearest, 1-farthest scale focus is stated on, which fog reads (ADR-0263).

Trait Implementations

impl Clone for CameraUniform

fn clone(&self) -> CameraUniform

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CameraUniform

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

Formats the value using the given formatter.

impl PartialEq for CameraUniform

fn eq(&self, other: &CameraUniform) -> 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 Zeroable for CameraUniform

fn zeroed() -> Self

Calls zeroed.

impl Copy for CameraUniform

impl Pod for CameraUniform

impl StructuralPartialEq for CameraUniform
