allowDataSourcesToSuspendAnimation

allowDataSourcesToSuspendAnimation: boolean

Defined in: node_modules/@cesium/engine/index.d.ts:44798

Gets or sets whether or not data sources can temporarily pause animation in order to avoid showing an incomplete picture to the user. For example, if asynchronous primitives are being processed in the background, the clock will not advance until the geometry is ready.

---

resolutionScale

resolutionScale: number

Defined in: node_modules/@cesium/engine/index.d.ts:44782

Gets or sets a scaling factor for rendering resolution. Values less than 1.0 can improve performance on less powerful devices while values greater than 1.0 will render at a higher resolution and then scale down, resulting in improved visual fidelity. For example, if the widget is laid out at a size of 640x480, setting this value to 0.5 will cause the scene to be rendered at 320x240 and then scaled up while setting it to 2.0 will cause the scene to be rendered at 1280x960 and then scaled down.

Inherited from

---

useBrowserRecommendedResolution

useBrowserRecommendedResolution: boolean

Defined in: node_modules/@cesium/engine/index.d.ts:44791

Boolean flag indicating if the browser's recommended resolution is used. If true, the browser's device pixel ratio is ignored and 1.0 is used instead, effectively rendering based on CSS pixels instead of device pixels. This can improve performance on less powerful devices that have high pixel density. When false, rendering will be in device pixels. CesiumWidget#resolutionScale will still take effect whether this flag is true or false.

Inherited from

CesiumWidget.useBrowserRecommendedResolution

---

useDefaultRenderLoop

useDefaultRenderLoop: boolean

Defined in: node_modules/@cesium/engine/index.d.ts:44773

Gets or sets whether or not this widget should control the render loop. If true the widget will use requestAnimationFrame to perform rendering and resizing of the widget, as well as drive the simulation clock. If set to false, you must manually call the resize, render methods as part of a custom render loop. If an error occurs during rendering, Scene's renderError event will be raised and this property will be set to false. It must be set back to true to continue rendering after the error.

CesiumWidget.useDefaultRenderLoop

flyTo()

flyTo(target, options?): Promise<boolean>

Defined in: node_modules/@cesium/engine/index.d.ts:44881

Flies the camera to the provided entity, entities, or data source. If the data source is still in the process of loading or the visualization is otherwise still loading, this method waits for the data to be ready before performing the flight.

The offset is heading/pitch/range in the local east-north-up reference frame centered at the center of the bounding sphere. The heading and the pitch angles are defined in the local east-north-up reference frame. The heading is the angle from y axis and increasing towards the x axis. Pitch is the rotation from the xy-plane. Positive pitch angles are above the plane. Negative pitch angles are below the plane. The range is the distance from the center. If the range is zero, a range will be computed such that the whole bounding sphere is visible.

In 2D, there must be a top down view. The camera will be placed above the target looking down. The height above the target will be the range. The heading will be determined from the offset. If the heading cannot be determined from the offset, the heading will be north.

Parameters

target

The entity, array of entities, entity collection, data source, Cesium3DTileset, point cloud, or imagery layer to view. You can also pass a promise that resolves to one of the previously mentioned types.

Entity | EntityCollection | DataSource | Entity[] | Cesium3DTileset | ImageryLayer | TimeDynamicPointCloud | Promise<Entity | EntityCollection | DataSource | Entity[] | Cesium3DTileset | ImageryLayer | TimeDynamicPointCloud | VoxelPrimitive>

options?

Object with the following properties:

duration?

number

The duration of the flight in seconds.

maximumHeight?

number

The maximum height at the peak of the flight.

offset?

HeadingPitchRange

The offset from the target in the local east-north-up reference frame centered at the target.

Returns

Promise<boolean>

A Promise that resolves to true if the flight was successful or false if the target is not currently visualized in the scene or the flight was cancelled. //TODO: Cleanup entity mentions

zoomTo()

zoomTo(target, offset?): Promise<boolean>

Defined in: node_modules/@cesium/engine/index.d.ts:44859

Asynchronously sets the camera to view the provided entity, entities, or data source. If the data source is still in the process of loading or the visualization is otherwise still loading, this method waits for the data to be ready before performing the zoom.

The offset is heading/pitch/range in the local east-north-up reference frame centered at the center of the bounding sphere. The heading and the pitch angles are defined in the local east-north-up reference frame. The heading is the angle from y axis and increasing towards the x axis. Pitch is the rotation from the xy-plane. Positive pitch angles are above the plane. Negative pitch angles are below the plane. The range is the distance from the center. If the range is zero, a range will be computed such that the whole bounding sphere is visible.

In 2D, there must be a top down view. The camera will be placed above the target looking down. The height above the target will be the range. The heading will be determined from the offset. If the heading cannot be determined from the offset, the heading will be north.

Parameters
