3D Datasets

Princeton Shape Benchmark: Dataset with 3D models for matching tasks. It provides software for evaluation.
National Taiwan University Dataset:Dataset and software for 3D models retrieval.
SHREC Datasets: A plethora of datasets related to 3D shape retrieval. It contains evaluations from different algorithms, so it is very useful for comparison.
McGill 3D Shape Benchmark: Collection of articulated 3D models.
TOSCA Dataset: 3D shapes devoted to non-rigid matching and analysis.
Sumner Dataset: 3D shape animations.
Brown Mesh Set: Collection of generic 3D objects.
AIM@SHAPE Shape Repository: Large collection of 3D models from several sources.

Useful Software

MeshLab: Tools for visualization, processing and analysis of 3D meshes.
OpenFlipper: Tools for processing of geometric data. It is built on top of the library OpenMesh to manipulate polygonal meshes.
Toolbox Graph: A MATLAB Toolbox to process graph and triangulated meshes.
Toolbox Fast Marching: A MATLAB Toolbox for Fast Marching and Level Sets computations. It is useful to compute geodesic distances on 3D meshes.
Heat Kernel Signatures: Implementation of HKS based on the Mesh Laplace Operator.
