Class ViewerNamespace

Add one more cutting plane beside the others and return its id, or null when it was not added: the viewer is at its limit (eight planes), or the plane is not enabled. A single-plane backend replaces its plane and returns null.

Hide entities

Isolate entities (hide everything else)

Remove the plane with this id (from getSections() or addSection()); false when there is none.

Reset color overrides. Omit refs for all; an explicit empty list is a no-op.

Reset all visibility to default

Set the selection to given entities

Set camera state

Switch projection mode

Set a section plane

Replace every cutting plane with sections, in order (the first becomes the active one). An empty list clears them all. A single-plane backend applies the first plane that is enabled.
