The method keeps the text-conditioned generator and geometry encoders frozen while training geometry projection, positional embedding, summary modules, and grounding adapters. Hull, avoidance, and touch meshes are encoded into compact geometry memory and routed to local regions of the TRELLIS sparse structure grid.
Arbor 3D is useful for artists and 3D generation researchers who need direct spatial control rather than only text or image prompts. It can preserve plausible object generation while satisfying typed geometric requirements and allowing variation in unconstrained regions.
