ThOR: Three-dimensional Object Retrieval Library.

Following the increasing number of 3D object collections, researchers developed several algorithms related to 3D object analysis, comparison and retrieval methods. However, there is no simple solution offering researchers and practitioners a framework for the integration of algorithms and techniques developed within this context into their applications and tools. ThOR (Three-dimensional Object Retrieval) is a lightweight open source Java library for content based object retrieval, that provides common 3D shape retrieval indexing and retrieval tools. Most important, it allows addition of new components, such as shape descriptors, with minimal effort. In short, ThOR provides an easy solution for the implementation of 3D object retrieval tools using both local and internet-based client-server architectures.
