SpatialBrain: Spatial Intelligence Growing from Experience
We present SpatialBrain, a framework that retains experience about these decisions while keeping its vision-language backbone fixed.

Key points
- Spatial reasoning requires more than access to geometric tools: a reasoner must decide when direct observation is sufficient and when to reconstruct, measure, or change reference frames.
- 3DFusionMemory fuses current-scene observations into queryable spatial relations.
- A Spatial Skill Library provides reusable tool procedures, and Spatial Cognition associates task conditions with experience about when and how to use memory and skills.
- Across five spatial-reasoning benchmarks, SpatialBrain improves on direct answers from the same backbone on four and ties on the fifth.
