The wildlife was vital for early man. Animals provided food, clothing and protection. This update introduces a fauna simulation which runs on top of the flora simulation. There are 2 kinds of animals: herbivores and carnivores. Both are simulated using logistic growth funtions. Animal growth is simulated for every tile of the roughly 1 million triangle size planet. There is also functionality which enables animals to migrate to find better food sources. This migration can give some nice cyclic behaviours similar to waves, which could give very interesting gameplay.
To learn more about the simulation, watch the devlog :)
