# MTL4RenderPassDescriptor

Describes a render pass.

```
class MTL4RenderPassDescriptor
```

## Overview

You use render pass descriptors to create instances of [`MTL4RenderCommandEncoder`](/documentation/Metal/MTL4RenderCommandEncoder) and encode draw
commands into instances of [`MTL4CommandBuffer`](/documentation/Metal/MTL4CommandBuffer).

To create render command encoders, you typically call [`renderCommandEncoderWithDescriptor:`](/documentation/Metal/MTL4CommandBuffer/renderCommandEncoderWithDescriptor:).
The [`makeRenderCommandEncoder(descriptor:options:)`](/documentation/Metal/MTL4CommandBuffer/makeRenderCommandEncoder(descriptor:options:)) variant of this method allows you to specify
additional options to encode a render pass in parallel from multiple CPU cores by creating *suspending* and *resuming*
render passes.
