LookAt

@Serializable

data class LookAt(val longitude: Double = 0.0, val latitude: Double = 0.0, val altitude: Double = 0.0, val heading: Double = 0.0, val tilt: Double = 0.0, val range: Double, val altitudeMode: AltitudeMode = AltitudeMode.clampToGround) : AbstractView

Defines a virtual camera that is associated with any element derived from Feature. The LookAt element positions the "camera" in relation to the object that is being viewed. In Google Earth, the view "flies to" this LookAt viewpoint when the user double-clicks an item in the Places panel or double-clicks an icon in the 3D viewer.

Constructors

LookAt

constructor(longitude: Double = 0.0, latitude: Double = 0.0, altitude: Double = 0.0, heading: Double = 0.0, tilt: Double = 0.0, range: Double, altitudeMode: AltitudeMode = AltitudeMode.clampToGround)

Properties

altitude

@XmlElement

val altitude: Double

Distance from the earth's surface, in meters. Interpreted according to the LookAt's altitude mode.

altitudeMode

@XmlElement

val altitudeMode: AltitudeMode

Specifies how the specified for the LookAt point is interpreted.

heading

@XmlElement

val heading: Double

Direction (that is, North, South, East, West), in degrees. Default=0 (North). Values range from 0 to 360 degrees.

horizFov

@XmlSerialName(value = "horizFov", namespace = "http://www.google.com/kml/ext/2.2", prefix = "gx")

val horizFov: Double

Defines the horizontal field of view of the AbstractView during a tour. This element has no effect on AbstractViews outside of a tour. horizFov is inserted automatically by the Google Earth client (versions 6.1+) during tour recording. Regular AbstractViews are assigned a value of 60; views within Street View are assigned a value of 85 to match the standard Street View field of view in Google Earth. Once set, the value will be applied to subsequent views, until a new value is specified.

latitude

@XmlElement

val latitude: Double

Latitude of the point the camera is looking at. Degrees north or south of the Equator (0 degrees). Values range from −90 degrees to 90 degrees.

longitude

@XmlElement

val longitude: Double

Longitude of the point the camera is looking at. Angular distance in degrees, relative to the Prime Meridian. Values west of the Meridian range from −180 to 0 degrees. Values east of the Meridian range from 0 to 180 degrees.

range

@XmlElement

val range: Double

Distance in meters from the point specified by longitude, latitude, and altitude to the LookAt position.

tilt

@XmlElement

val tilt: Double

Angle between the direction of the LookAt position and the normal to the surface of the earth. Values range from 0 to 90 degrees. Values for tilt cannot be negative. A tilt value of 0 degrees indicates viewing from directly above. A tilt value of 90 degrees indicates viewing along the horizon.
