Randomized trial demonstrates enhanced 3D scene synthesis in indoor environments, suggesting improved design flexibility.

The aim is to synthesize realistic 3D indoor scenes by addressing data scarcity and ensuring both architectural constraints and semantic consistency.
Developed a cascaded diffusion framework with four sub-stages: predicting furniture categories, refining object sizes, modeling spatial relationships, and generating OBBs.
Introduced a sparse relation graph to replace dense relation graphs, improving relational controllability.
Utilized a bidirectional Variational Autoencoder to encode the sparse graphs into a latent space.
Achieved state-of-the-art performance in fidelity and diversity of generated 3D scenes.
Enhanced controllability in layouts, allowing better respect for functional organization and physical validity.
Reduced data requirements while enabling integration of Large Language Models and Vision Language Models for zero-shot tasks.

Wu et al. (2026) studied this question.
