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.

• altitude(_:)

  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>)

• bounds(latitude:longitude:)

  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>)

• heading(_:)

  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>)

• tilt(_:)

  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>)
