SpatialBrain: Spatial Intelligence Growing from Experience

One-line takeaway

SpatialBrain accumulates spatial-reasoning experience with a frozen VLM backbone, combining 3DFusionMemory for scene relations, a Spatial Skill Library of reusable tool procedures, and a cognition module that decides when to use them.

SpatialBrain 在视觉语言主干冻结的情况下积累空间推理经验：用 3DFusionMemory 存场景空间关系、空间技能库存可复用工具流程，再由空间认知模块决定何时调用记忆和技能。
