# MDLNoiseTexture

A generator of texel data that creates a field of random noise.

## Declaration

```swift
class MDLNoiseTexture
```

## Overview

Overview Like other procedural MDLTexture subclasses, the MDLNoiseTexture class generates texel data only when that data is first referenced, and then caches it for future use.
