# MeshTransform

> Contains transform information related to a tracked mesh.

## Definition

* **Type:** Struct
* **Namespace:** [UnityEngine.XR](/engine/6000.6/script-reference/unityengine/xr.md)
* **Assembly:** UnityEngine.XRModule
* **Implements:** [IEquatable\<MeshTransform>](https://learn.microsoft.com/dotnet/api/system.iequatable-1)

```csharp
public readonly struct MeshTransform : IEquatable<MeshTransform>
```

## Remarks

This struct is used by the [XRMeshSubsystem](/engine/6000.6/script-reference/unityengine/xr/xrmeshsubsystem.md) to communication information about a mesh's transform.
