Hi Croxis,
Very interesting ! I’m trying to develop a stellar system editor, and I just discovered Panda3D and python…
I’m going to try to understand your app and I think we’ll have some discussion in a near future ^-^ See you soon !
EDIT #1 : see my orbital camera code snippet. Next I’ll try to copy your app while retaining my camera system.
EDIT #2 : Gamasutra articles are quite interesting, the log Z-buffer w/ scaling and the use of impostors are great ideas.
