 - In the first collection, we consider synthetically acquired noisy cubes and spheres.
 - The second collection consists of abstract shapes and is made up of two subcollections each composed of 25 shapes.
 - The third part consists of the categorized shapes of the Princeton Segmentation Benchmark (Chen et al., "A Benchmark for 3D Mesh Segmentation", TOG, 28.3, 2009).
