List of Geometrical Optics Interface Physics Features
The Geometrical Optics Interface has the following nodes and subnodes (listed in alphabetical order) available from the Physics ribbon toolbar (Windows users), Physics context menu (Mac or Linux users), or right-click to access the context menu (all users).
In general, to add a node, go to the Physics toolbar, no matter what operating system you are using. Subnodes are available by clicking the parent node and selecting it from the Attributes menu.
