Implementations

impl ArcballControls

pub fn new() -> Self

pub fn active_gesture(&self) -> Gesture

pub fn pointer_down(&mut self, x: f64, y: f64, button: i32) -> bool

Begin a gesture. Returns true when the pointer is captured for camera interaction.

pub fn pointer_move(&mut self, camera: &mut ViewCamera, x: f64, y: f64) -> bool

Advance the active gesture; mutates the camera. Returns true when the camera changed (the dirty signal).

pub fn pointer_up(&mut self) -> bool

End the gesture. Returns true if one was active.

pub fn touch_navigation( &mut self, camera: &mut ViewCamera, from: [f64; 2], to: [f64; 2], scale: f64, ) -> bool

Direct two-finger navigation in viewport pixels. Zoom about the previous midpoint, then carry that point to the new midpoint. Unlike wheel input, the distance ratio is applied exactly, without notch sensitivity.

pub fn wheel( &mut self, camera: &mut ViewCamera, delta_y: f64, cursor: Option<[f64; 2]>, ) -> bool

Wheel zoom about the target. delta_y is in egui POINTS (see ZOOM_PER_NOTCH); negative = zoom in. Returns true when the camera changed.
