# encode(commandBuffer:primaryTexture:secondaryTexture:destinationTexture:)

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

## Declaration

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

## Parameters

- `commandBuffer`: A valid command buffer to receive the encoded kernel.
- `primaryTexture`: A valid texture containing the primary source image.
- `secondaryTexture`: A valid texture containing the secondary source image.
- `destinationTexture`: A valid texture to be overwritten by the result image. destinationTexture may not alias primaryTexture nor secondaryTexture.
