# encode(commandBuffer:sourceTexture:destinationTexture:)

Encodes a kernel into a command buffer, out of place.

## Declaration

```swift
func encode(commandBuffer: any MTLCommandBuffer, sourceTexture: any MTLTexture, destinationTexture: any MTLTexture)
```

## Parameters

- `commandBuffer`: A valid command buffer to receive the encoded kernel.
- `sourceTexture`: A valid texture containing the source image.
- `destinationTexture`: A valid texture to be overwritten by the result image. destinationTexture may not alias sourceTexture.
