VIGOR: Verifiable Industrial Geometry Optimization and Repair in Scene Programs

The paper introduces VIGOR, a system that enhances large language model–generated industrial scene programs by adding verification and staged geometric refinement to ensure engineering feasibility. It builds a dataset of 1,749 industrial scenarios with executable programs and 94 geometric checks each, and uses supervised fine‑tuning, local projection, and conflict‑graph repair to address violations. VIGOR achieves a 96.86% complete feasibility rate and outperforms baselines by 10.42 points in overall score.
