3D PDF: How to zoom to a part/node/mesh

Hi,

I need to zoom a part of a 3d modell e.g. one node/mesh by javascript. I aready could select a node or a mesh but I'm not sure how I could isolate it.

In the adobe GUI is very simple to do it  "Select a Node"-> "Right click"-> "Part options"->"Zoom To Part". I know there are some more options in the API which are not documented: How to make spin tool default

Option2: Is a possible to set the Camera-Object to a target like a node?

Best regards,
