flatshaded

Flatshaded refers to a rendering technique in 3D computer graphics that displays polygonal surfaces with a uniform color across each entire polygon. Unlike smooth shading methods, which interpolate colors across polygons to create the illusion of curves and subtle lighting variations, flat shading applies a single color or shade to each face of a 3D model. This results in a distinct, faceted appearance, where the edges of individual polygons are clearly visible.

The process involves calculating the lighting at a single point on each polygon, typically at its center or a vertex, and then applying that determined color to the entire polygon. This approach is computationally inexpensive compared to more complex shading models, making it suitable for real-time applications where performance is a critical factor, such as in early video games or mobile applications.

The characteristic look of flat shading is often described as angular, geometric, or cel-shaded, depending on the artistic intent. While it can appear dated or simplistic in certain contexts, it can also be used intentionally as an artistic choice to achieve a specific aesthetic. This style was prevalent in early 3D graphics due to hardware limitations and remains a viable option for projects prioritizing speed or a distinct visual style over photorealism.
