TomTom SDK for iOS ControlPoint

ControlPoint

public struct ControlPoint : Equatable

The camera configuration for a given distance to the next instruction on the route. Intermediate values are obtained by linear interpolation between the corresponding points.

  • Creates a new ControlPoint instance.

    Declaration

    Swift

    public init(distance: Measurement<UnitLength>, tilt: Double, zoom: Double, fieldOfView: Double = 45)

    Parameters

    distance

    Distance to the next route instruction from which the following camera configuration is applied.
    tilt

    Optional tilt to be applied to the camera when the corresponding distance is reached.
    zoom

    Zoom to be applied. Must be greater than zero.
    fieldOfView

    Optional field of view (FOV), in degrees, to be applied. By default, it is 45.

  • Distance to the next route instruction from which the following camera configuration is applied. Its value must be greater than zero.

    Declaration

    Swift

    public let distance: Measurement<UnitLength>

  • Optional tilt to be applied to the camera when the corresponding distance is reached. It must range from 0 to 90. If tilt is not provided, a tilt value of 0 is used.

    Declaration

    Swift

    public let tilt: Double

  • Zoom to be applied. Its value must be greater than zero.

    Declaration

    Swift

    public let zoom: Double

  • Optional field of view (FOV), in degrees, to be applied. This must be in the range from 1.0 to 150.0 (inclusive). If no value is provided, then the default value of 45.0 is used. The FoV used may be different from the entered value, depending on the camera scale:

    • If the camera zoom is less than ~13.7, then the FoV value defined in the camera control point will be used.
    • If the camera zoom is in the range [13.7..12.4], the FoV is adjusted to approach 45 degrees. The amount of adjustment increases proportionately with the camera scale. The FoV for a camera scale close to 12.4 will be adjusted to be close to 45 degrees. The FoV for a camera scale closer to 3.7 will have less adjustment applied to it.
    • If the camera scale is greater than 12.4, the default value of 45 degrees for the field of view will be used.

    Declaration

    Swift

    public let fieldOfView: Double
