Photorealistic rendering is a highly effective illustration tool which allows a project to be visualized, making it easier to present ideas and make design decisions. It can also attract clients by convincing them that a project will look as good as it does in the rendering, as well as sell ideas by creating an emotional connection to the product with photorealism. Ultimately, photorealistic renderings imitate how objects look in the real world, including how light shines and reflects on them, shadows they create, what they are made of, and their textures.
