Jmol filter
De MoodleDocs
Jmol is open-source Java software for interactive 3D viewing of molecular structures. It can easily be embedded into a webpage... including a Moodle page.
The Jmol filter is recently developed but comes as a single download and is easy to use and install.
It requires no additional capability on your web server, but is a Java applet, added to the page with JavaScript controls, so requires both Java and a JavaScript-enabled browser for the user.
