How to import 3d object using Universal viewer?

I already install Universal viewer and i am trying to import a 3d object. Does anyone knows what extension i have to use or how i can do it?

The plugin is only a wrapper around the widget UniversalViewer, that implemented the common 3D format of Three.js (see http://threejs.org and https://en.wikipedia.org/wiki/Three.js ). See an example of a little model of the Kiss of Rodin here.

I updated the plugin (version 2.2.4) to simplify the display of 3D models. See https://github.com/Daniel-KM/UniversalViewer4Omeka#3d-models.
