Please review the 3d extension.
This extension enables upload of, thumbnailing, and interactive viewing of three-dimensional model files, currently only the STL file format, but with the potential for expansion based on request.
We intend to enable this on beta-commons, then the testwikis, then on Commons to see how file uploaders make use of it. If all of those experiments go well, and we are able to respond to requests, we will push the extension out to other wikis to allow use of models across the projects.
Target dates for deployments: 2017-03-01 for beta, 1-2 weeks later for test, 1-2 weeks later for Commons.
The command-line utility used for thumbnailing, 3d2png, was already reviewed - T132063
