# RawRenderPass\<U *extends* [`UniformValues`](../../../types/types/type-aliases/UniformValues.md) = `Record`<`string`, `never`>>

```ts
type RawRenderPass<U extends UniformValues = Record<string, never>> =
  Disposable & {
    render: (opts?: RawRenderOptions) => void;
    target: RenderTarget | null;
    setTarget: (target: RenderTarget | null) => void;
    setSize: ({ width, height }: { width: number; height: number }) => void;
    getResolution: () => [number, number];
    uniforms: U;
    vertex: string;
    fragment: string;
    onUpdated: (callback: UpdatedCallback<U>) => void;
    onBeforeRender: (callback: RenderCallback) => void;
    onAfterRender: (callback: RenderCallback) => void;
    onInit: (callback: (gl: WebGL2RenderingContext) => void) => void;
    onResize: (callback: (width: number, height: number) => void) => void;
    onDispose: (callback: () => void) => void;
    initialize: (gl: WebGL2RenderingContext) => void;
  };
```

A low-level rendering pass that encapsulates shaders, concrete uniforms, and attributes.
