Struct Camera 

pub struct Camera {
    pub center: Point,
    pub zoom: f64,
    pub rotation: f64,
}

f64 inverse-view parameters; scene time remains caller-owned.

Fields

center: Point

World point placed at the current design viewport’s center.

zoom: f64

Positive logical units per world unit.

rotation: f64

Clockwise camera orientation in radians; content rotates oppositely.

Implementations

impl Camera

pub fn world_to_screen( self, context: &SceneContext<'_>, point: Point, ) -> Result<Point, ValidationError>

Projects a world point without clipping or including ancestor transforms.

pub fn screen_to_world( self, context: &SceneContext<'_>, point: Point, ) -> Result<Point, ValidationError>

Unprojects a design-viewport point, including points outside the viewport.
