 Each zip file when unzipped generates the folders corresponding to its object classes. For GSO.zip, a folder called GSO is created. For the remaining zip files, folders are created labeled by the the ShapeNetCore IDs of the 8 classes used in the dataset. Within each class folder, object models are stored in the subfolder hierarchy '[classID]/[objectID]/models/'. The value of '[classID]' corresponds to the ShapeNetCore ID or 'GSO'. The value of '[objectID]' corresponds to the ShapeNetCore object model ID for ShapeNetCore models and to the object model descriptor name with underscores as used to name object models in GSO. The use of the same ShapeNetCore class IDs, and ShapeNetCore or GSO object IDs enables one-to-one cross-referencing with the original ShapeNetCore and GSO datasets.
 
 Within each '[classID]/[objectID]/models' subfolder, models are stored as triangular meshes in the PLY file format (https://gamma.cs.unc.edu/POWERPLANT/papers/ply.pdf) as follows: 
-- The waterproofed version of the original model is provided in the file 'model_c.ply', where 'c' stands for complete.
-- The fractured (i.e. 'broken') models generated by the primitive subtraction are stored in files with the nomenclature 'model_b_[N].ply'. Here, 'b' stands for `broken', and N E {0,1,...,N_max-1} represents the index for the N+1th fractured mesh. N_max is 3 for jars and bottles, 10 for mugs, and 1 for the rest of the classes.
-- Fragments generated from the broken mesh are stored as 'model_r_[N]_fragment[M].ply', where M E {0,1,...} represents the index for the M+1th fragment.

 - The fragment 'model_b_[N]_fragment0.ply' represents the broken mesh fragment with the largest volume.
-- Fragments generated from the repair mesh are stored as 'model_r_[N]_fragment[M].ply', where, 'r' stands for `repair' and M E {0,1,...} represents the index for the M+1th repair mesh fragment. It should be noted that the number of repair mesh fragments typically differs from the number of broken mesh fragments. In the interest of space, the original repair mesh is not shared, however, can be generated either as the union of the repair fragments or as the Boolean subtraction of the complete mesh and the broken mesh.

+In the interest of storage, the original broken and repair meshes generated from subtraction (i.e., the meshes prior to fragmenting connecting components) are not shared. However, they can be generated as a union of the corresponding mesh's fragments.
