Property Overview

Property Details

declaredClassStringreadonly

The name of the class. The declared class name is formatted as esri.folder.className.

fovNumber

The field of view of the camera in degrees.

Default Value: 55

headingNumber

The compass heading of the camera in degrees. Heading is zero when north is the top of the screen. It increases as the view rotates clockwise. The angles are always normalized between 0 and 360 degrees.

Default Value: 0

Examples:

// Initialize the view with a specific camera
var cam = new Camera({
  heading: 90, // face due east
  tilt: 45, // looking from a bird's eye view
  position: [ -122, 38, 20000 ]  // creates a point instance (x,y,z)
});

// Initialize the view with a specific camera
var cam = new Camera({
  heading: 90, // face due east
  tilt: 45, // looking from a bird's eye view
  position: {
    latitude: 38,
    longitude: -122,
    z: 20000,
    spatialReference: { wkid: 3857 }
  }
});

view.camera = cam;

// Set the heading of the view's camera to 180 degrees
var newCam = view.camera.clone();
newCam.heading = 180;
view.camera = newCam;

// go to the pt geometry facing due south
view.goTo({ target: pt, heading: 180 });

positionPoint autocast

The position of the camera defined by a map point.

Z-values defined in a geographic or metric coordinate system are expressed in meters. However, in local scenes that use a projected coordinate system, vertical units are assumed to be the same as the horizontal units specified by the service.

Example:

var cam = view.camera.clone();
// the position is autocast as an esri/geometry/Point object
cam.position = {
  latitude: 38,
  longitude: -122,
  z: 50000  // altitude in meters
}
// go to the new camera
view.goTo(cam);

tiltNumber

The tilt of the camera in degrees with respect to the surface as projected down from the camera position. Tilt is zero when looking straight down at the surface and 90 degrees when the camera is looking parallel to the surface.

Default Value: 0

Examples:

// Initialize the view with a specific camera
var cam = new Camera({
  heading: 90, // face due east
  tilt: 45, // looking from a bird's eye view
  position: {
    latitude: 38,
    longitude: -122,
    spatialReference: { wkid: 3857 }
  }
});

view.camera = cam;

// go to the pt geometry facing directly down
view.goTo({ target: pt, tilt: 0 });

Method Overview

Method Details

clone(){Camera}

Creates a deep clone of the camera object.

Returns:

Type	Description
Camera	A deep clone of the Camera instance that invoked this method.

Example:

// clone the view's camera since its geometry cannot be directly modified
var cam = view.camera.clone();
// the position is autocast as an esri/geometry/Point object
cam.position = {
  latitude: 38,
  longitude: -122,
  spatialReference: { wkid: 3857 }
}
// set the view to the new camera
view.camera = cam;

fromJSON(json){*}static

Creates a new instance of this class and initializes it with values from a JSON object generated from a product in the ArcGIS platform. The object passed into the input json parameter often comes from a response to a query operation in the REST API or a toJSON() method from another ArcGIS product. See the Using fromJSON() topic in the Guide for details and examples of when and how to use this function.

Parameter:

json Object A JSON representation of the instance in the ArcGIS format. See the ArcGIS REST API documentation for examples of the structure of various input JSON objects.

Returns:

Type	Description
*	Returns a new instance of this class.

toJSON(){Object}

Converts an instance of this class to its ArcGIS Portal JSON representation. See the Using fromJSON() topic in the Guide for more information.

Returns:

Type	Description
Object	The ArcGIS Portal JSON representation of an instance of this class.
