ImmerseGen: Agent-Guided Immersive World Generation with Alpha-Textured Proxies

ImmerseGen is an agent-guided framework that builds immersive VR worlds from lightweight geometric proxies carrying synthesized RGBA textures, rather than exhaustive geometry. Vision-language model agents handle asset placement and add visual dynamics and ambient sound. The authors report better photorealism, spatial coherence, and rendering efficiency than existing methods, including real-time performance on mobile VR headsets.
