Text-to-Infinite-World: Real-Time Generative 3D Environments
In early generative AI, text prompts produced static 2D images or short video clips. In 2026, spatial foundation models generate navigable, fully interactive 3D virtual worlds complete with physically based rendering (PBR) materials, collision geometry, and dynamic audio reverb profiles.
#1. The Generative Spatial Pipeline
Generating an explorable environment requires solving consistency across multiple representations:
