In 3D computer graphics, normal mapping, or Dot3 bump mapping, is a texture mapping technique used for faking the lighting of bumps and dents - an implementation of bump mapping. It is used to add details without using more polygons.

All normal map textures you create are your own. Textures are not saved on the server and all scripts are running on your Browser. Normal Maps are textures that inherit depth information of a surface.

To get normal mapping to work we're going to need a per-fragment normal. Similar to what we did with diffuse and specular maps we can use a 2D texture to store per-fragment normal data.

Normal maps are a type of Bump Map. They are a special kind of texture that allow you to add surface detail such as bumps, grooves, and scratches to a model which catch the light as if they are...

Today we will talk about normal mapping. Since Tutorial 8 : Basic shading, you know how to get decent shading using triangle normals. One caveat is that until now, we only had one normal per...

That normal map is in tangent-space, but you are treating it as object-space. You need a bitangent and/or tangent vector per-vertex in addition to your normal in order to form the basis to perform...

Tangent space normal map: this is the most common normal map nowadays, and the one we have been talking about in the previous parts of this tutorial. It modifies the normal direction of the model...

Normal maps can be improved greatly by learning the implementation details. To eliminate seams and shading artifacts, the game engine and the normal map baking tool should use the same tangent basis. For more information about a synched workflow see the Polycount Forum thread You're making me...

Triple-A game assets such as characters, weapons, and environments rely heavily on normal mapping in order to look good. But what is normal mapping... and why is its use so widespread?
