# MDLCamera

A point of view for rendering a 3D scene, along with a set of parameters describing an intended appearance for rendering.

## Declaration

```swift
class MDLCamera
```

## Overview

Overview Camera parameters include basic information—such as the projectionMatrix and fieldOfView properties—for use with any renderer, as well as attributes that model real-world cameras—such as the fStop and exposure properties—for use in a renderer based on realistic optical physics.
