Controllable automatic generation of non-player characters in 3D anime style

Abstract

Game creators always use prefabricated models as non-player characters (NPCs) to create an atmosphere for game scenes. However, players are likely to see different NPCs with the same 3D models. We introduced a neural network, Gaussian mixture models, a Bayesian network to control their facial appearances, colors of hair and clothes, and outfits, respectively. It is demonstrated that the proposed approach can maintain the variety and stability of the generated characters.
