I think of that patch as more of a bugfix than a new feature, so i didn't think it was necessary to mention in the release notes. However, it should make the plotting quite a bit faster (you can plot lots of points in not very much time, but it's harder to plot lots of spheres). Maybe one of the best applications would be a 3d vector field, where you want to plot lots and lots of vectors very quickly. So maybe the plot_vector_field3d function would provide a good example (see http://trac.sagemath.org/sage_trac/ticket/2646). I've posted a picture there. Basically, that command (the last function defined in the comments on the ticket) should provide a lot more responsive picture than before, because it now plots line3d objects instead of full arrow objects. I've published an example here: http://sagenb.org/home/pub/474/ You can get the picture by clicking on the Get Image link next to the 3d plot after adjusting the angle to whatever you want. For what it's worth, that plot_vector_field3d at #2646 just needs some documentation, and then I think it's ready to go into Sage too.
