Sketchfab for Atto is a new and small plugin for the Atto text editor which enables you to embed the sketchfab content to rich content areas within Moodle.
You can add any sketchfab content into your Moodle course just by clicking the button in your Atto toolbar, paste a link to a Sketchfab model and the plugin will do the work of embedding a good-looking thumbnail into your post for you.
Sketchfab is a free service for publishing and searching the best 3D content. For more details about Sketchfab, check out the official website: https://sketchfab.com/
As an example, you can embed the 3D Moodleframe using this link: http://sketchfab.com/models/028d91eadb424857a82d119ea5a269a5
You can also combine this plugin with moodle-filter_sketchfab, a text filter plugin which provides options for automatically replacing these thumbnails with the embedded Sketchfab viewer.
