Hi Andreas, This is a neat idea! It would be great to have a nice open-source tool for this, as all of the useful ones today are very expensive and proprietary.
As far as I know (others please correct me if I am wrong), there isn't currently any functionality to generate polygons from the entire copper of a layer. Poured zones are represented as polygons, so those are easy, but tracks are represented differently. So, you would likely need to write some code to convert the copper items other than zones (i.e. tracks, vias, pads, etc) to polygons so you can mesh them. You might want to look at the 3D viewer for inspiration, since it already does a similar task of extracting all the design data in order to render it in 3D. You can see in ./3d-viewer/3d_canvas/create_layer_items.cpp some of the code that does this, so it might be a good starting point.
