Struct CamLayout 

pub struct CamLayout {
    pub center: Vec2,
    pub radius: f32,
}

Position + size of the circular webcam bubble within the composed frame. All coordinates are NDC — (-1, -1) bottom-left, (1, 1) top-right.

Fields

center: Vec2

Centre of the circle in NDC.

radius: f32

Radius in NDC units. The default 0.18 makes the bubble roughly 18% of the viewport’s shorter side, matching the Screen Studio convention.

Implementations

impl CamLayout

pub const BOTTOM_RIGHT: Self

Bottom-right corner with a 24 px-equivalent NDC margin (~0.05 in [-1, 1] space) and a radius of 0.18 (~18% of viewport).

pub const BOTTOM_LEFT: Self

Bottom-left variant — the current default. Mirrors the Screen Studio bottom-left cam placement convention; flip to Self::BOTTOM_RIGHT for right-handed presenters.

pub const TOP_LEFT: Self

Top-left variant.

Trait Implementations

impl Clone for CamLayout

fn clone(&self) -> CamLayout

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CamLayout

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

Formats the value using the given formatter.

impl Default for CamLayout

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for CamLayout

fn eq(&self, other: &CamLayout) -> 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 CamLayout
