Complex Lighting With Normal Maps
In our last article we talked about adding "Dynamic Shadows" for clouds. Today we will talk about dynamic lights and how the implementation works. With Unity, lighting and shading from lights can be introduced in many different ways but how we created it within a 2D space was through normal maps. Normal mapping is a texture mapping technique used for faking the lighting of bumps and dents and is an implementation of bump mapping. Many developers use normal mapping to add details without having to use more polygons for a given model. This increases detail without the performance hit from the extra polygons.
