Final answer:
Engineering projects are often drawn in three-point perspective, which allows for depicting objects from a bird's-eye or worm's-eye view with realistic depth.
Step-by-step explanation:
Engineering projects such as bridges and piping installations are commonly drawn in three-point perspective. This type of perspective is used to create a sense of depth and realism in technical drawings, which is essential for accurately conveying how these structures will exist in a three-dimensional space. The orthogonals in three-point perspective drawings converge at three vanishing points, often with two on the horizon and one either above or below, depending on the viewpoint (bird's-eye or worm's-eye).
This approach contrasts with the one-point and two-point perspectives that typically have vanishing points on the horizon line only. Renaissance contributions to engineering, such as those by Filippo Brunelleschi, included the development of linear perspective and technical drawing techniques, revolutionizing the communication and execution of architectural and engineering designs.
