The Theia open source library for 3D modeling, written by UCSB PhD student Chris Sweeney, won first place in the Association for Computing Machinery Multimedia (ACM MM) Open Source Software competition. Finalists for the award gave presentations at ACM Multimedia where the award was announced. A photo of Chris presenting at the competition is featured above along with some photos of 3D models generated by the Theia library. More information about the contest can be found here.


The Theia library provides students, researchers, and industry experts with a clean C++ library including a state-of-the-art Structure-from-Motion pipeline and a vast collection of multi-view geometry tools and algorithms that utilize image and video inputs to create high quality 3D reconstructions. All algorithms are intentionally designed to be scalable, and multithreaded computation is utilized automatically whenever possible. Theia is very modular and was designed so that all algorithms can be easily extended, modified, or used independently of the rest of the library making it useful for researchers designing new algorithms. Since being released in February 2015 Theia has gathered an active community of users spanning graduate students, industry members, and computer vision experts.
