Mira-Scene: Pixel-Aligned Layouts for Generative 3D Scene

A new method called Mira-Scene addresses the challenge of pixel-aligned layouts for generative 3D scenes, targeting the difficulty of accurately placing high-fidelity single-image 3D objects into a coherent scene. The approach focuses on how object layout is represented, contrasting with holistic methods that absorb placement into a scene-level generation process.

Single-image 3D object generation can now produce high-fidelity assets, yet accurately placing them into a coherent scene layout remains an open challenge. A central difficulty lies in how object layout is represented. Holistic methods absorb placement into a scene-level generation process, sacrific
