Taiting Lu, Kaiyuan Lin, Mingjia Wang, Haolin Ye, Runze Liu, Yuxin Tian, et al.
Recent large language models (LLMs) have demonstrated remarkable progress in 3D spatial reasoning, spatial grounding, and fine-grained geometric understanding. However, their ability to reason about densely packed object placement under strict spatial and functional constraints r…
