Three point perspective should be used when drawing a building from close up by looking up or down at it, as it introduces a third vanishing point allowing the artist to depict a bird's-eye or worm's-eye view. To draw in three point perspective, an artist places vertical lines converging to three vanishing points situated on the horizon line. Examples of works that effectively employ three point perspective include da Vinci's Last Supper, Caillebotte's Paris Street; Rainy Day, and Escher's Tower of Babel. The document instructs the reader to create their own cityscape using three point perspective.
