Flat shading

Flat shading is the shading model with this blocky lo-fi look which bears nostalgic vibes of the early 90s' games. Every model in 3D is a combination of vertices that define the shape. Each vertex has its own normal that we use to determine the amount of 3D lighting to apply to that vertex. As a result, each polygon receives an equal amount of light with flat shading without mathematical correction that makes the object look sharp and flat.^[1]
