Constructors

constructor

new OLCSCamera(scene: Scene, map: Map): OLCSCamera
This object takes care of additional 3d-specific properties of the view and ensures proper synchronization with the underlying raw Cesium.Camera object.
Parameters
- scene: Scene
- map: Map
Returns OLCSCamera
- Defined in Camera.ts:67

Methods

calcDistanceForResolution

calcDistanceForResolution(resolution: number, latitude: number): number
calculate the distance between camera and centerpoint based on the resolution and latitude value
Parameters
- resolution: number
  Number of map units per pixel.
- latitude: number
  Latitude in radians.
Returns number
The calculated distance.
- Defined in Camera.ts:433

calcResolutionForDistance

calcResolutionForDistance(distance: number, latitude: number): number
calculate the resolution based on a distance(camera to position) and latitude value
Parameters
- distance: number
- latitude: number
Returns number
The calculated resolution.
- Defined in Camera.ts:448

checkCameraChange

checkCameraChange(opt_dontSync?: boolean): void
Check if the underlying camera state has changed and ensure synchronization.
Parameters
- Optionalopt_dontSync: boolean
  Do not synchronize the view.
Returns void
- Defined in Camera.ts:415
