The transparency of geometry parts depends on the distance of the eyepoint to
the geometry. In the draw callback this is calculated and applied to the polygons.

Yes, it is a billboard.
A second type of transparent object in the scene is also custom rendered in
a draw callback because it contains coplanar geometry. For witch I haven't found
a way to implement with pfLayer, because I need a complete transparent base layer.
And these should be sorted back to front together with the other transparent objects.
