Dataset

There are two challenges:

• Irregular holes

The downloads are split in parts due to server-side limitations. Please download all parts one at a time (i.e. not simultaneously).

test set: download 1 2 (1078 shapes, ~310MB)

training set: 1 2 (1216 shapes, ~325MB)

These shapes have random scale, random position in space, multiple connected components, irregular mesh, and span several resolutions. See figure (top) for some examples.

• Range data

test set: download (882 shapes, ~35MB)

training set: download (1082 shapes, ~45MB)

These shapes have inconsistent scale, multiple connected components, and regular (grid-like) topology. The meshes span several resolutions, and are approximately aligned and upright oriented. See figure (bottom) for some examples.

You can participate to either challenge or both. The dataset is composed of transformed versions of shapes belonging to the TOSCA and the SHREC'16 Topology benchmarks.

Shapes are given in OFF format. A Matlab script to load the shapes can be downloaded here.
