One way is to create a new node with browser::create_vrml_from_stream
and add it to the scene.

Another is to get the "Viewpoint" node_type from the scope and create a
new node from it:

        your_browser.root_nodes()[0]->scope()->find_type("Viewpoint")->create_node(...);

I'm not sure what you mean here because you don't appear to be using
VRML's nomenclature.

Changes to the user view are always relative to the active Viewpoint
node. You can change the position and orientation of a Viewpoint node;
or you can change the translation and rotation of one of its parent
Transform nodes.
