DotProduct3 is a high-level bump mapping technique, it can achieve per-pixel lighting without pixel shader.
With DotProduct3 bump mapping, a normal map is used to represent per-pixel 3-space normals to a surface. At each pixel, it is possible to compute a dotproduct with another 3-space vector which represents the vector to a given light source.

In Awakening, you can use this technique by writing Shader Text.
See sample:

(to open the sample scene in Awakening, just first copy 'effects' and 'textures' folders to Awakening's install folder.)

In the next version of Awakening, full DotProduct3 support:
