# LowLevelTextureResource

A container for texture data in a custom format.

## Declaration

```swift
final class LowLevelTextureResource
```

## Overview

Overview Use LowLevelTextureResource when you want to bring your own texture data to the renderer or update your data frequently. Textures are updated on the GPU by writing to a MTLTexture returned by replace(commandBuffer:). The descriptor is analogous to MTLTextureDescriptor.

## Topics

### Accessing the descriptor
