Struct ResolvedCamera 

pub struct ResolvedCamera {
    pub eye: Vec3,
    pub target: Vec3,
    pub up: Vec3,
    pub projection: Projection,
    pub near: f32,
    pub far: f32,
}

A resolved camera: concrete framing plus the matrices and projection the backend and label layer need. Stored in Scene3DData.

Fields

eye: Vec3

World-space eye position.

target: Vec3

World-space look-at point.

up: Vec3

Up vector — always Vec3::Y from CameraState::resolve (pitch clamping keeps it from degenerating).

projection: Projection

How the camera projects (perspective for 3D, orthographic for 2D).

near: f32

Near clip-plane distance from the eye, world units.

far: f32

Far clip-plane distance from the eye, world units.

Implementations

impl ResolvedCamera

pub fn orthographic(center: Vec2, half_w: f32, half_h: f32) -> ResolvedCamera

An orthographic camera that maps the scale-space window centred at center with half-extents (half_w, half_h) to the full rect — the 2D-plot data-layer camera. Looks straight down -Z at the z = 0 plane the 2D geometry lives on; aspect is ignored (the half-extents already encode the window’s shape).

pub fn view(&self) -> Mat4

Right-handed look-at view matrix.

pub fn proj(&self, aspect: f32) -> Mat4

Projection matrix for aspect (width/height), 0..1 depth range (wgpu convention). Perspective uses aspect; orthographic ignores it.

pub fn view_proj(&self, aspect: f32) -> Mat4

proj(aspect) * view() — the matrix backends upload.

pub fn project_to_screen(&self, world: Vec3, viewport: Rect) -> Option<Vec2>

Project a world point to screen-space (logical px) within viewport. Returns None for points at or behind the camera plane (w <= 0), so label callers cull them rather than drawing a mirrored ghost. Points in front but outside the rect still return Some — clipping to the rect is the caller’s choice.

pub fn project_to_screen_with_depth( &self, world: Vec3, viewport: Rect, ) -> Option<(Vec2, f32)>

Like project_to_screen but also returns the point’s normalised device depth in [0, 1] (wgpu convention: 0 near, 1 far) — the same space a Depth32Float buffer stores, so callers can depth-test a projected anchor against a captured scene depth map. None when the point is at/behind the camera.

Trait Implementations

impl Clone for ResolvedCamera

fn clone(&self) -> ResolvedCamera

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ResolvedCamera

impl Debug for ResolvedCamera

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

Formats the value using the given formatter.

impl PartialEq for ResolvedCamera

fn eq(&self, other: &ResolvedCamera) -> 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.
