Camera.withLocation constructor

Camera.withLocation({
  1. required ArcGISPoint location,
  2. required double heading,
  3. required double pitch,
  4. required double roll,
})

Creates a camera with the specified location, heading, pitch, and roll. The camera's spatial reference is derived from the locationPoint.

Parameters:

  • location — A point geometry defining the 3D location at which to place the camera. If the point has a spatial reference, the camera will adopt it. Otherwise, a spatial reference of WGS84 is assumed. If the point's z value is below the ArcGISScene.baseSurface and the Surface.navigationConstraint is set to NavigationConstraint.stayAbove, the camera will be positioned at the Surface. Note that the default is NavigationConstraint.stayAbove.
  • heading — The angle around the z-axis at which the camera is rotated. The angle is clockwise from north in the East, North, Up (ENU) ground reference frame. The value is between 0 and 360, where 0 is looking North and 90 is looking East. Values are wrapped modulo 360 (for example, 370 becomes 10).
  • pitch — The angle around the x-axis at which the camera is rotated in the East, North, Up (ENU) ground reference frame. The value is between 0 and 180, where 0 is looking straight down, 90 is looking towards the horizon, and 180 is looking straight up. Pitch values are clamped to this range: a negative value defaults to 0 and a value greater than 180 defaults to 180. If the behavior of a negative pitch is required, then the corresponding transformation with positive pitch can be set instead. For example, if heading:0 pitch:-20 roll:0 is required then heading:180 pitch:20 roll:180 can be used instead.
  • roll — The angle around the y-axis (the direction of sight) at which the camera is rotated in the East, North, Up (ENU) ground reference frame. Positive values rotate counterclockwise in view space (for example, when looking north, 90 means the top of the screen points west). The value is between 0 and 360, where 0 is horizontal and 180 is upside down. Values are wrapped modulo 360 (for example, 370 becomes 10).
