0 A.D. is a free, open-source, cross-platform real-time strategy (RTS) game of ancient warfare. It's a historically-based war/economy game that allows players to relive or rewrite the history of six ancient Western civilizations, from Iberia to Persia, each depicted at their peak of economic growth and military prowess. Developed using Pyrogenesis, a ground-breaking new game engine custom-built to suit this project, 0 A.D. will give players a rich and entertaining real-time gaming experience.
Open Source contributor, myconid, has been working on adding additional visual enhancements to 0 A.D.'s graphics engine. One of these enhancements is Ambient Occlusion, which simulates a measure of how much each part of the model is illuminated by indirect sunlight (mainly from the sky or other objects).
On the right is the current lighting implementation and on the left is the ambient occlusion light map applied by myconid's changes. The engine would pre-render the light maps for all of the models in the game, removing the need for artists and modders to bake textures or render light maps themselves in Blender or 3DS Max. This would happen dynamically for each new model as it's added to the game.
