With the rapid rise of generative AI and large-scale world models, game computer graphics (CG) is undergoing a major transformation. This Birds of a Feather session will focus on how CG technologies in games evolve in the AI era, with particular emphasis on Non-Player Characters (NPCs), including personality-aligned generation of text, voice, expressions, and motions, multi-view consistent stylized rendering, and self-evolution. We will also discuss how world models can support more immersive virtual games. Distinguished researchers will share their insights, aiming to foster collaboration across research and development communities.
