# PhotogrammetrySample

An object that represents one image and its corresponding metadata.

## Declaration

```swift
struct PhotogrammetrySample
```

## Overview

Overview This object holds a single input image for constructing 3D objects from a series of photographs, along with the image’s metadata, such as EXIF data or information about a depth buffer, an object mask, or gravity vector. Use a  unique id for each PhotogrammetrySession so RealityKit can distinguish different PhotogrammetrySample instances in status updates, error messages, and other contexts.
