BlueprintAgent: Constraint-Triggered Targeted Revisits for Simulation-Ready Generation from Scanned Structural Blueprints
Zhouyuan Xu, Chen Yang, Linhao Wang +2
Converting in-service reinforced-concrete (RC) building blueprints into simulation-ready models---structured frame representations that support deterministic FEM export and qualifi…
Beyond Arbitrary Geometry: Topology Generalization In neural PDE Operators
Peiyao Chen, Zhouyuan Xu, Ran Ding +3
Neural operators that accept arbitrary meshes are often treated as geometry-general, but unseen domain topology changes both the invariant and decaying subspaces of a PDE operator.…
PhysMind: From Video to Executable Worlds for Training-Free Physical Reasoning
Chen Yang, Shenxiang Zeng, Haoyang Zhao +6
Reliable physical reasoning from video requires understanding how objects move, interact, and respond to interventions. Existing vision-language models (VLMs) often struggle to int…
Thinking in Structures: Evaluating Spatial Intelligence in Constraint-Governed Spaces
Chen Yang, Guanxin Lin, Youquan He +10
Spatial intelligence is crucial for vision--language models (VLMs), yet many scene-centric benchmarks evaluate unconstrained environments where a single image may admit multiple pl…
