Normal Mapping
A shading trick that stores surface direction in a purple-blue texture so flat low-polygon models look richly detailed under lights. Developed from mid-to-late-1990s research, it became a cornerstone of later real-time 3D games.
Spot it
- 01Fine fake surface bumps
- 02Lit grooves on flat shapes
- 03Smooth low-poly silhouettes
Why it happens
Each texel encodes a surface direction as RGB, and lighting uses it instead of the true geometry, producing detailed shading without any extra polygons.

Image edit prompt“Render this image as a low-polygon model enhanced with normal mapping: smooth, simple silhouettes with intricate stitched seams, rivets, scales and fine pores shaded convincingly by a moving light, crisp specular glints, and detail that stays flat when seen at a steep angle. Keep the original subject and composition.”
