WpsLocation

Contains world positioning data from the WPS (World Positioning System)....

---

Declaration

struct WpsLocation

Summary

Contains world positioning data from the WPS (World Positioning System). WpsLocation provides global positioning information that combines GPS/GNSS data with visual positioning for enhanced accuracy and reliability.

Overview

WPS location data includes:

• Reference GPS coordinates (latitude, longitude, altitude)
• Transformation matrix for coordinate conversions
• Status information about positioning quality

Example Usage

let (status, location) = wpsSession.latestLocation()
if status.isOk() {
    print("GPS Coordinates: \(location.referenceLatitudeDegrees), \(location.referenceLongitudeDegrees)")
    print("Altitude: \(location.referenceAltitudeMetres) meters")
    print("Status: \(location.status)")
    
    // Use the transformation matrix for coordinate conversions
    let worldPosition = location.trackingToRelativeEdn
    placeARContent(at: worldPosition)
}

Properties

Name	Type	Summary
var description	String	A textual representation of this instance. Calling this property directly is discouraged. Instead, convert an instance of any type to a string by using the String(describing:) initializer. This initializer works with any type, and uses the custom description property for types that conform to CustomStringConvertible: struct Point: CustomStringConvertible { let x: Int, y: Int var description: String { return "(\(x), \(y))" } } let p = Point(x: 21, y: 30) let s = String(describing: p) print(s) // Prints "(21, 30)" The conversion of p to a string in the assignment to s uses the Point type's description property.
let referenceAltitudeMetres	Double	Reference altitude in meters above sea level. This represents the GPS altitude of the reference point used for WPS positioning calculations.
let referenceLatitudeDegrees	Double	Reference latitude in degrees (WGS84 coordinate system). This represents the GPS latitude of the reference point used for WPS positioning calculations.
let referenceLongitudeDegrees	Double	Reference longitude in degrees (WGS84 coordinate system). This represents the GPS longitude of the reference point used for WPS positioning calculations.
let trackingToRelativeEdn	simd_float4x4	Transformation matrix from tracking to relative coordinate system. This 4x4 transformation matrix converts between the tracking coordinate system and the relative coordinate system used for AR content placement.
