Benchmark dataset of diverse 3D meshes for evaluating convex decomposition methods. Used by visibility-decomposition to compare visibility-based decomposition against V-HACD and CoACD.

Dataset Composition

Subset	Meshes	Format	Description
CoACD Examples	5	.obj	Smoke-test meshes from the CoACD repo
ArtVIP	528	.obj	Per-link meshes from 205 articulated objects across 5 categories
SceneSmith	500	.glb	Stratified sample of generated objects from SceneSmith scenes

Total: 1,033 meshes
