How QuatRoPE Breaks 3D Spatial Reasoning Bottlenecks for Large Language Models

The paper introduces QuatRoPE, a quaternion‑based 3D position embedding that, together with the IGRE isolation mechanism and the ASR benchmark, dramatically improves large language models' ability to encode and reason about object relationships in 3D scenes, as demonstrated by extensive experiments on multiple 3D VL datasets.
