AnchorTrackingState

Represents the current tracking state of a VPS anchor....

Declaration​

enum AnchorTrackingState

Summary​

Represents the current tracking state of a VPS anchor. The tracking state indicates how well the system is able to track an anchor's position and orientation in the current environment.

Cases​

NameTypeSummary
case limitedReason?)
The anchor is being tracked with limited accuracy.
Tracking information is available, but is of poor quality and should
not be relied upon at close distances.
case notTrackedReason?)
The anchor is not currently being tracked.
case trackedtracked
The anchor is being tracked with full accuracy.

Properties​

NameTypeSummary
var descriptionString
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.

Operators​

NameTypeSummary
static func != Bool
Returns a Boolean value indicating whether two values are not equal.
Inequality is the inverse of equality. For any values a and b, a != b
implies that a == b is false.
This is the default implementation of the not-equal-to operator (!=)
for any type that conforms to Equatable.
- Parameters:
- lhs: A value to compare.
- rhs: Another value to compare.

Nested Types​

Enums​

NameTypeSummary
ReasonReason
Provides additional context about why an anchor is in either the notTracked
or limited tracking states.
