See how you can almost intuitively understand the curvature and the general outline of the coin? That’s exactly what a normal map helps computers do. Normal maps are created by gathering data from a 3D model-or simply a texture-and projecting it onto a 2D image. They are typically used for bump mapping, a technique meant to create more realistic 3D models and higher quality details on those models without incurring the performance costs of using actual geometry. Normal maps are textures that can make a surface appear bumpy, reflecting light differently on parts of the object based on the angle of the surface, creating the illusion of depth. ![]() In this article, I’m going to explain a very important subset of those maps that help give your 3D models more depth and all-around can make them look much better & more detailed. ![]() If you’re new to the 3D world, you might’ve heard the words “Normal Map” or any other assortment of wonderful maps with wacky names being thrown around.
