Tetris3D: 3D Scene Generation With Objects That Fit Together

Jaeyeong Kim, Jinhyuk Jang, Jongmin Lee et al.1 min readHugging FaceOct 7, 2026

Key Takeaway for Students

We propose Tetris3D, a generative framework for single-image 3D scene reconstruction that recovers objects which are physically and geometrically coherent as a scene. Existing methods often generate objects independently or couple them implicitly, providing limited guidance for ensuring fine-grained spatial compatibility between neighboring objects that interact with one anothe

state-of-the-art performance in both generation quality and physical stabili

This work addresses a critical challenge in 3D scene generation by ensuring physical and geometric coherence between objects, moving beyond independent generation. For ML engineers, this signifies a shift towards more realistic and interactive virtual environments, impacting areas like robotics, gaming, and simulation.
