Members

Sets the duration, in seconds, of the bounce back animations in 2D and Columbus view.
Default Value: 3.0

enableCollisionDetection : boolean

Enables or disables camera collision detection with terrain.
Default Value: true
If true, inputs are allowed conditionally with the flags enableTranslate, enableZoom, enableRotate, enableTilt, and enableLook. If false, all inputs are disabled. NOTE: This setting is for temporary use cases, such as camera flights and drag-selection of regions (see Picking demo). It is typically set to false at the start of such events, and set true on completion. To keep inputs disabled past the end of camera flights, you must use the other booleans (enableTranslate, enableZoom, enableRotate, enableTilt, and enableLook).
Default Value: true
If true, allows the user to use free-look. If false, the camera view direction can only be changed through translating or rotating. This flag only applies in 3D and Columbus view modes.
Default Value: true
If true, allows the user to rotate the world which translates the user's position. This flag only applies in 2D and 3D.
Default Value: true
If true, allows the user to tilt the camera. If false, the camera is locked to the current heading. This flag only applies in 3D and Columbus view.
Default Value: true
If true, allows the user to pan around the map. If false, the camera stays locked at the current position. This flag only applies in 2D and Columbus view modes.
Default Value: true
If true, allows the user to zoom in and out. If false, the camera is locked to the current distance from the ellipsoid.
Default Value: true
A parameter in the range [0, 1) used to determine how long the camera will continue to spin because of inertia. With value of zero, the camera will have no inertia.
Default Value: 0.9
A parameter in the range [0, 1) used to determine how long the camera will continue to translate because of inertia. With value of zero, the camera will have no inertia.
Default Value: 0.9
A parameter in the range [0, 1) used to determine how long the camera will continue to zoom because of inertia. With value of zero, the camera will have no inertia.
Default Value: 0.8
The input that allows the user to change the direction the camera is viewing. This only applies in 3D and Columbus view modes.

The type came be a CameraEventType, undefined, an object with eventType and modifier properties with types CameraEventType and KeyboardEventModifier, or an array of any of the preceding.

Default Value: { eventType : CameraEventType.LEFT_DRAG, modifier : KeyboardEventModifier.SHIFT }
A parameter in the range [0, 1) used to limit the range of various user inputs to a percentage of the window width/height per animation frame. This helps keep the camera under control in low-frame-rate situations.
Default Value: 0.1
允许相机的最大俯仰角,仅作用于 3D 场景模式,ScreenSpaceCameraController#lookEventTypes 不受限制。
Default Value: 90.0
The maximum magnitude, in meters, of the camera position when zooming. Defaults to positive infinity.
Default Value: Number.POSITIVE_INFINITY

minimumCollisionTerrainHeight : number

The minimum height the camera must be before testing for collision with terrain.
Default Value: 15000.0

minimumPickingTerrainDistanceWithInertia : number

The minimum distance the camera must be before testing for collision with terrain when zoom with inertia.
Default Value: 4000.0

minimumPickingTerrainHeight : number

The minimum height the camera must be before picking the terrain instead of the ellipsoid.
Default Value: 150000.0
允许相机的最小俯仰角,仅作用于 3D 场景模式,ScreenSpaceCameraController#lookEventTypes 不受限制。
Default Value: -90.0
The minimum height the camera must be before switching from rotating a track ball to free look when clicks originate on the sky or in space.
Default Value: 7500000.0
The minimum magnitude, in meters, of the camera position when zooming. Defaults to 1.0.
Default Value: 1.0
从深度缓冲中拾取深度时使用的高度。
Default Value: 1.0
从深度缓冲中拾取深度时使用的宽度。
Default Value: 1.0
The input that allows the user to rotate around the globe or another object. This only applies in 3D and Columbus view modes.

The type came be a CameraEventType, undefined, an object with eventType and modifier properties with types CameraEventType and KeyboardEventModifier, or an array of any of the preceding.

Default Value: CameraEventType.LEFT_DRAG
返回 tilting 时的世界坐标,见 ScreenSpaceCameraController#tiltEventTypes
The input that allows the user to tilt in 3D and Columbus view or twist in 2D.

The type came be a CameraEventType, undefined, an object with eventType and modifier properties with types CameraEventType and KeyboardEventModifier, or an array of any of the preceding.

Default Value: [CameraEventType.MIDDLE_DRAG, CameraEventType.PINCH, { eventType : CameraEventType.LEFT_DRAG, modifier : KeyboardEventModifier.CTRL }, { eventType : CameraEventType.RIGHT_DRAG, modifier : KeyboardEventModifier.CTRL }]
当前是否处于 tilting 状态,见 ScreenSpaceCameraController#tiltEventTypes
Default Value: false
The input that allows the user to pan around the map. This only applies in 2D and Columbus view modes.

The type came be a CameraEventType, undefined, an object with eventType and modifier properties with types CameraEventType and KeyboardEventModifier, or an array of any of the preceding.

Default Value: CameraEventType.LEFT_DRAG
The input that allows the user to zoom in/out.

The type came be a CameraEventType, undefined, an object with eventType and modifier properties with types CameraEventType and KeyboardEventModifier, or an array of any of the preceding.

Default Value: [CameraEventType.RIGHT_DRAG, CameraEventType.WHEEL, CameraEventType.PINCH]

Methods

Removes mouse listeners held by this object.

Once an object is destroyed, it should not be used; calling any function other than isDestroyed will result in a DeveloperError exception. Therefore, assign the return value (undefined) to the object as done in the example.
Throws:
  • DeveloperError : This object was destroyed, i.e., destroy() was called.
Example:
controller = controller && controller.destroy();
See:
Returns true if this object was destroyed; otherwise, false.

If this object was destroyed, it should not be used; calling any function other than isDestroyed will result in a DeveloperError exception.
Returns:
true if this object was destroyed; otherwise, false.
