The field of 3D scene layout generation and modeling is rapidly evolving, with a focus on developing more efficient, accurate, and robust methods. Recent research has explored the use of vision-guided systems, stepwise evolution paradigms, and hierarchical reasoning frameworks to generate high-quality 3D scene layouts. Additionally, there is a growing interest in procedural scene programs, geometry-augmented CAD model generation, and structured 3D modeling using LLM agents. These advancements have the potential to significantly impact various applications, including digital content creation, procedural generation, and spatial reasoning. Noteworthy papers include: Imaginarium, which presents a novel vision-guided 3D layout generation system, and ShapeCraft, which introduces a multi-agent framework for text-to-3D generation. SEGA and Procedural Scene Programs also demonstrate innovative approaches to content-aware layout generation and open-universe scene generation, respectively. GACO-CAD and Structural Tree Extraction from 3D Surfaces showcase promising methods for CAD model generation and structural analysis.
