Interactive 3D model of a fantasy world with unusual architecture and landscapes

Prompt

Create a cinematic browser-based 3D world that can be explored freely with a camera, focused on breathtaking landscapes and extraordinary original architecture. Fill the world with huge strange buildings, monumental structures, surreal ruins, cliffs, valleys, forests, water, and unusual ultra-detailed forms that feel mysterious and awe-inspiring. This is not a game and not combat-focused, the goal is pure exploration, atmosphere, composition, and visual discovery. Make the world feel epic, highly detailed, and completely original, with architecture that looks weird, ambitious, and unforgettable.
