WorldScore's 3D Consistency runs DROID-SLAM on a generated static-world clip and averages the reprojection error of co-visible pixels between consecutive frames, then maps it to 0-100 against an empirical worst case (a frame-interpolated clip between unrelated images). Reported scores: Gen-3 68.31, Hailuo 67.18, DynamiCrafter 72.90, CogVideoX-I2V 86.21, 3D scene generators LucidDreamer 90.37 and WonderWorld 86.87. Its authors check it with human pairwise tests (91.7% and 97.3% agreement for 30-point bucket gaps); an independent injected-warp test found it good on scene-level but weak on object-level deformation. In code it assumes a fixed lens and cannot score dynamic subjects.
