    "body_text": "SpaceFlow is a training-free 3D generation pipeline built around geometric primitives that stand in for object parts. Each primitive receives its own control level, allowing one region to follow input geometry closely while another permits generative completion. After structure generation, the system segments the result, matches parts back to primitives and routes only the assigned text or image cue to each region, reducing cross-part leakage. Regional metrics and a user study support the claimed balance between local adherence and plausible variation. The work demonstrates controllability on the reported examples; it does not guarantee watertight geometry, manufacturability or faithful reconstruction.",
