Experimentations using Sprite Lamp, software created by Snake Hill Games for lighting 2D bitmap images using generated normal maps. The design is attempting to build an entire game using pixel art graphics, but dynamically and three dimensionally lit in a realtime graphics engine. This art style has not been attempted before.
You can see the diffuse map characters on the top, created with no shading. Underneath is the result of hand-creating multiple lighting maps and using them to create a normal map which then solves for the dynamic light. Lastly, there is a diagram explaining the planned 3D space of the game which will be responsible for generating the orthographic view that the player is presented with.
