Two notes. Castle and x3dom use 'render' as field name, and Holger had<br>
also suggested using a positive field name.<br>

links to ~Viewport~, somehow.<br>

Here is a working link:<br>

<br>
Not sure if listing a viewpoint description in the ui is similar<br>
enough to rendering a shape to require the same naming of the fields.<br>
But 'displayed' would be an option. 'visible' is another suggestion,<br>
'shown' would be shorter, 'show' even shorter.<br>
