# GeometrySource

A container for geometrical vector data.

## Declaration

```swift
struct GeometrySource
```

## Overview

Overview Mesh-anchor geometry (MeshDescriptor) uses geometry sources to hold 3D data like vertices and normals in an efficent, array-like format. A Metal buffer wraps the data and other properties specify how to interpret that data. If componentsPerVector is greater than one, the element type of the geometry-source array is itself a sequence (pairs, triplets, and so on).
