# LowLevelRenderContext

An entry point for creating rendering resources and compiling materials.

## Declaration

```swift
protocol LowLevelRenderContext : AnyObject
```

## Overview

Overview Use a LowLevelRenderContext to construct meshes, textures, buffers, argument tables, materials, and pipeline states. These objects are assembled into a LowLevelMeshInstanceArray consumed each frame by LowLevelRenderer.
