After the "layers", now the ... "multi-layers" ! ;-)

Here's the latest in addons technology 
The "layers" concept was introduced in 2008 for Celestia 1.6.0. Now in 2009, we have the "multi-layers". Basically, it's a generalisation of the layers concept for Celestia : a single script let the user to switch various layers, one at a time. The experience feels a bit like "PowerPoint".
Here's an example applied to the Milky Way's galactic center, using several layers of billboards (click the picture to enlarge) :
The billboards are adjusted very precisely, using the galactic center and the Pistol star.
The Sgr A* addon I created recently can be shown in front of the billboards, to give some explanations in a classroom :
Or the central black hole :
The new multi-layers technique will introdue a new class of addons in the near future. Here's the CELX script associated to the previously shown galactic addon (sorry, the comments are in French) :
The addon will be published once I find some good server. The problem is that I now have a large number of new "layers" addons to be published !
