; Flat Shading: A technique that shades each polygon of an object based on the polygon's "normal" and the position and intensity of a light source.

; [[Gouraud Shading]]: Invented by H. Gouraud in 1971, a fast and resource-conscious vertex shading technique used to simulate smoothly shaded surfaces.

; [[Texture Mapping]]: A technique for simulating a large amount of surface detail by mapping images (textures) onto polygons.

; [[Phong Shading]]: Invented by Wu Tong Phong, used to simulate specular highlights adnand smooth shaded surfaces.

; [[Bump Mapping]]: Invented by [[Jim Blinn]], a normal-perturbation technique used to simulate wrinkled surfaces.

; [[Ray Tracing]]: A shading technique used to simulate reflection and transparency.
