# ARGeometryPrimitiveType

The kind of connection between vertices.

## Declaration

```swift
enum ARGeometryPrimitiveType
```

## Overview

Overview When you enable sceneReconstruction on a world-tracking configuration, ARKit provies a wireframe mesh that models the shape of the real world using a collection of connected vertices. ARKit uses ARGeometryPrimitiveType to indicate how a particular property of that mesh is interpreted. For example, a mesh geometry’s faces property specifies that each face within the geometry is of type ARGeometryPrimitiveType.triangle.
