Flat shading is a simple rendering technique used in computer graphics to give objects a solid color without any gradients or highlights. Each polygon of a 3D model is assigned a single color, which creates a blocky appearance. This method emphasizes the shape and structure of the object, making it easier to see its geometric form. This technique is often used in video games and animations where a stylized look is desired. It can also be found in art styles like low-poly design, where simplicity and clarity are prioritized over realism. Flat shading is effective for creating a distinct visual style.
