Definition & Meaning of "toon shading"

What is "toon shading"?

Toon shading is a technique used in computer graphics to give 3D models a flat, cartoon-like appearance. Instead of using realistic gradients and smooth transitions, toon shading applies distinct color areas with sharp edges, mimicking the look of traditional 2D animation or comic book art. This method emphasizes bold outlines and simplified color zones, creating a stylized, graphic effect that makes 3D objects appear as if they were hand-drawn or painted. It is commonly used in video games and animated films to achieve a distinctive, cartoonish aesthetic.
