Seeing Both the Forest and the Trees: Reusing Holistic 3D Priors for Part-Decomposed Generation
STRUCTPARTS is a framework for part-decomposed generation that allows models to combine geometric detail and structural coherence from a holistic 3D prior. It achieves this using dual-frame coordinate interleaving, where each part is processed locally as a complete shape and globally as part of an object. This enables superior performance in decomposition quality and supports training-free refinement and editing.
