A new benchmark called TriViewBench has been developed to assess the structural reasoning capabilities of Multimodal Large Language Models (MLLMs). The benchmark, comprising synthetic 3D scenes with varying object counts and occlusions, reveals that all 18 evaluated MLLMs exhibit a consistent performance hierarchy, with capabilities degrading significantly as complexity increases. Specifically, global recovery tasks collapse severely, while object counting also shows substantial degradation. The research indicates that current MLLMs face fundamental scalability limitations in cross-view spatial representation, and Chain-of-Thought prompting offers minimal benefit. AI
