CameraRestriction

  enum 
 CameraRestriction 
 

Represents various constraints that can be applied to the camera’s position or orientation.

Use these cases to define limits on camera properties like altitude, heading, tilt, or geographical bounds, often used to guide user interaction or enforce specific viewing perspectives within a map or scene view.

  • Restricts the camera’s altitude (height above ground or sea level).

    Note

    If you attempt to set a value less than 0.0 , it will be clamped to 0.0 . If you attempt to set a value greater than 63170000.0 , it will be clamped to 63170000.0 .

    Declaration

    Swift

      case 
     altitude 
     ( 
     any 
     RangeExpression 
     < 
     Double 
     > 
     ) 
     
    
  • When set, restricts the position of the camera within the specified lat/lng bounds. Note that objects outside the bounds are still rendered. Bounds can restrict both longitude and latitude, or can restrict either latitude or longitude only. For latitude-only bounds use longitude range of (-180.0)...180 . For longitude-only bounds use latitude range of -(90)...90 `.

    Declaration

    Swift

      case 
     bounds 
     ( 
     latitude 
     : 
     ClosedRange 
     < 
     Double 
     > 
     , 
     longitude 
     : 
     ClosedRange 
     < 
     Double 
     > 
     ) 
     
    
  • Restricts the camera’s heading (horizontal direction or azimuth).

    Note

    If you attempt to set a value less than 0.0 , it will be clamped to 0.0 . If you attempt to set a value greater than 360.0 , it will be clamped to 360.0 .

    Declaration

    Swift

      case 
     heading 
     ( 
     any 
     RangeExpression 
     < 
     Double 
     > 
     ) 
     
    
  • Restricts the camera’s tilt (pitch angle relative to the horizon).

    A tilt of 0 typically means looking straight down, while 90 might represent looking towards the horizon, depending on the specific camera system’s convention.

    Note

    If you attempt to set a value less than 0.0 , it will be clamped to 0.0 . If you attempt to set a value greater than 90.0 , it will be clamped to 90.0 .

    Declaration

    Swift

      case 
     tilt 
     ( 
     any 
     RangeExpression 
     < 
     Double 
     > 
     )
