P3D-Bench - Text-to-3D Parametric Geometry: leaderboard
Metric: Geometry bucket score (0-100) (equal-weight mean of normalized F-scores at 0.05 and 0.01, normal consistency, Chamfer distance and IoU) on 400 Text-to-3D cases from parametric specifications (minimal JSON and OpenSCAD outputs), the model writes a parametric CAD program that is compiled, meshed and aligned to the ground truth; invalid outputs take the worst value; each general model runs with its maximum thinking budget; averaged over the output formats; higher is better. Source: arxiv.org. Saturation forecast: Around August 2027. 9 models tracked.
