SpatialGrammar: A Domain-Specific Language for LLM-Based 3D Indoor Scene Generation
Researchers introduce SpatialGrammar, a domain-specific language designed to improve LLM-based 3D indoor scene generation by representing layouts as bird's-eye-view grid placements with compiler validation. The approach, paired with SG-Agent (an iterative refinement system) and SG-Mini (a 104M-parameter model), significantly reduces spatial errors and collision issues that plague existing natural language-to-3D scene generation methods.
