Large Scale Comprehensive 3D Shape Retrieval.

The objective of this track is to evaluate the performance of 3D shape retriev al approaches on a large-sale comprehensive 3D shape database that contains different types of models,such as generic, articulated, CAD and architecture models. The track is based on a new comprehensive 3D sha pe benchmark, which contains 8,987 triangle meshes that are classified into 171 categories. The benchmark w as compiled as a superset of existing benchmarks and presents a new challenge to retrieval methods as it com prises generic models as well as domainspecific model types. In this track, 14 runs have been submitted by 5 gro ups and their retrieval accuracies were evaluated using 7 commonly used performance metrics.
