Researchers have developed SpaR3D-MoE, a novel framework designed to enhance the 3D spatial reasoning capabilities of Multimodal Large Language Models (MLLMs) using only sparse RGB inputs. The system employs an adaptive spatiotemporal manifold sampling mechanism to create a geometry-aware graph, preserving scene connectivity while reducing redundancy. Additionally, a geometry-inductive Mixture-of-Experts with an instruction-pose aware router adaptively directs multimodal tokens to specialized experts, resolving cross-modal contention. Experiments on benchmarks like VSI-Bench, ScanQA, and SQA3D show SpaR3D-MoE achieving state-of-the-art performance, notably scoring 63.5 on VSI-Bench and significantly improving performance on specific tasks.
