The McGill 3D
Shape Benchmark offers a repository for testing 3D shape retrieval
algorithms. The emphasis is on including models with articulating
parts. Thus, whereas some models have been adapted from the
the Princeton Shape
Benchmark and others have been downloaded from different web repositories,
a substantial number have been created by us using CAD modeling tools.
We provide the models in both "voxelized" form (using the .im file format, corresponding
to the KUIM package) as well as in "mesh" form (using the .ply format).
In the voxelized format voxels within the interior of an object have a different
label than those in the background. In the mesh format each object's surface is
provided in triangulated form. The mesh representations correspond to
the boundary voxels of the corresponding voxel representations. They are therefore
are "jagged" and may need to be smoothed for some applications.
The models are organized in two databases. The first contains
objects with articulating parts and the second objects whose parst undergo
minor or no articulation. Within each database there are a number of ``basic'' level categories
and in each there are typically between 20 to 30 examplars.
