It's not a matter of convenience -- after two hours with the PPE
sources, I was scarcely any more enlightened than I am now.

We've already begun this discussion, but it's worth repeating that
this should be core functionality for a scene-graph API -- any 3D
editor or any game or simulation that allows the user to interact with
the scene graph using the mouse (i.e. to manipulate objects) will need
to do this.

If someone can explain what I need to do, I'll be happy to contribute
an ssgSelect() function so that we won't have to rehash this thread in
the future:

  ssgEntity ** ssgSelect (ssgRoot * root, ssgContext * context,
                          int mouse_x, int mouse_y);

(or something similar.)


All the best,


David
