# ARMeshGeometry

Mesh information stored in an efficient, array-based format.

```
class ARMeshGeometry
```

## Overview

The information in this class holds the geometry data for a single anchor of the scene mesh. Each vertex in the anchor’s mesh represents one connection point. Every three-vertex combination forms a unique triangle called a *face*. Each face includes an outside-directional normal and a [`classification`](/documentation/ARKit/ARMeshGeometry/classification). If ARKit cannot classify a particular face, the value is `0`, –– the raw value for [`ARMeshClassification.none`](/documentation/ARKit/ARMeshClassification/none).

## Topics

### Accessing Geometry Data

[`vertices`](/documentation/ARKit/ARMeshGeometry/vertices)

The vertices of the mesh.

[`ARGeometrySource`](/documentation/ARKit/ARGeometrySource)

Mesh data in a buffer-based array.

### Getting Geometry Information

[`classification`](/documentation/ARKit/ARMeshGeometry/classification)

Classification for each face in the mesh.

[`ARMeshClassification`](/documentation/ARKit/ARMeshClassification)

Enumeration of different classes of real-world objects that ARKit can identify.

[`faces`](/documentation/ARKit/ARMeshGeometry/faces)

An object that contains a buffer of vertex indices of the geometry’s faces.

[`ARGeometryElement`](/documentation/ARKit/ARGeometryElement)

A container for index data, such as vertex indices of a face.

[`normals`](/documentation/ARKit/ARMeshGeometry/normals)

Rays that define which direction is outside for each face.
