}

Options for the fly_to animation.

Mirrors the MapLibre/Mapbox FlyToOptions API.

All fields are optional. When omitted, the animation retains the camera’s current value for that property.

Fields

center: Option<GeoCoord>

Target geographic center. If None, the center does not change.

zoom: Option<f64>

Target zoom level. If None, the zoom does not change.

bearing: Option<f64>

Target bearing (yaw) in radians. If None, bearing does not change.

The animation always takes the shortest angular path.

pitch: Option<f64>

Target pitch in radians. If None, pitch does not change.

curve: f64

The zooming “curve” (? in the van Wijk paper).

Higher values produce more exaggerated zoom-out. Default: 1.42 (the user-study average from van Wijk 2003).

speed: f64

Average speed in ?-screenfulls per second. Default: 1.2.

Ignored when duration is set explicitly.

screen_speed: Option<f64>

Average speed in screenfulls per second (overrides speed).

Ignored when duration is set explicitly.

duration: Option<f64>

Explicit animation duration in seconds.

When set, speed / screen_speed are ignored and the animation runs for exactly this duration.

min_zoom: Option<f64>

The zoom level at the peak of the flight path.

When set, curve is overridden to produce a zoom-out that reaches this zoom level.

max_duration: Option<f64>

Maximum allowed duration in seconds.

If the auto-computed duration exceeds this, the animation degrades to an instant jump_to.

easing: Option<fn(f64) -> f64>

Easing function f(t) -> k where t and k are both in [0, 1].

Default: cubic-bezier(0.25, 0.1, 0.25, 1.0) (MapLibre default).
