# EnvironmentProbeAnchor

An environment probe in the world.

```
struct EnvironmentProbeAnchor
```

## Overview

Use environment probes to light virtual geometry by producing environment textures from the probe’s location in the world.

> Note:
> The framework always positions the anchor at the location of the Vision Pro device.

## Topics

### Getting anchor information

[`var environmentTexture: (any MTLTexture)?`](/documentation/ARKit/EnvironmentProbeAnchor/environmentTexture)

The environment texture of an anchor.

[`var cameraScaleReference: Float`](/documentation/ARKit/EnvironmentProbeAnchor/cameraScaleReference)

The camera scale reference of this anchor.

[`var originFromAnchorTransform: simd_float4x4`](/documentation/ARKit/EnvironmentProbeAnchor/originFromAnchorTransform)

The transform from the environment probe anchor to the origin coordinate system.

### Comparing environment probe anchors

[`var id: UUID`](/documentation/ARKit/EnvironmentProbeAnchor/id)

The unique identifier of this anchor.

[`var description: String`](/documentation/ARKit/EnvironmentProbeAnchor/description)

A textual representation of this anchor.

### Operators

[`static func == (EnvironmentProbeAnchor, EnvironmentProbeAnchor) -> Bool`](/documentation/ARKit/EnvironmentProbeAnchor/==(_:_:))

Returns a Boolean value indicating whether two environment probe anchors are equal.
