Wishlist: export 3D render from python interface or command line

Description

When I finish a board, I usually need to export a bunch of files for the manufacturer and the client to review. An important part of this is exporting 3D renders of the board so the client can do a quick visual check for problems without having to do a mechanical check in a MCAD application (silkscreen information missing/misplaced, component placement, etc.).

What I wish is for a way to automate the export of the 3D view of the board.

I don't mind doing it through the pcbnew python interface or by calling a command on the command line (similar to kicad2step). What I find important is a way to set the following before exporting:

  • Camera position
  • Camera rotation/panning
  • Zoom factor
  • Others?

I'm not really sure what the parameters should be called since I don't have experience of setting up this kind of "scene".

This would probably be related/could help with #3690.
