Help:Extension:3D

3d is an extension that simply adds support for three-dimensional model files in MediaWiki.

Currently, it supports the STL format, but it could be expanded to support others.

If this extension is installed on your wiki, the only step needed to use it is to upload an STL file to the wiki via the help>Special:MyLanguage/Help:Upload|usual methods.

Once the file is there, the file page and any file links will use the new thumbnailer, and help>Special:MyLanguage/Help:Extension:Media Viewer|the media viewer extension will use the new client-side interactive viewer.
