# isRasterizationEnabled

Determines whether the pipeline rasterizes primitives.

```
var isRasterizationEnabled: Bool { get set }
```

## Discussion

By default, this value is <doc://com.apple.documentation/documentation/Swift/true>, specifying that this pipeline
rasterizes primitives. Set this property to <doc://com.apple.documentation/documentation/Swift/false> when you
don’t provide a fragment shader function via function [`fragmentFunctionDescriptor`](/documentation/Metal/MTL4RenderPipelineDescriptor/fragmentFunctionDescriptor).
