However, existing methods (such as Holodeck and Chat-3D) suffer from severe limitations: generic foundation models lack spatial ergonomic intuition, frequently producing floating assets, blocked walkways, and inverted furniture orientations. Moreover, relying solely on static 3D datasets lacks the iterative revision loop characteristic of human interior designers.
