>> Could you explain what you mean by impostor ? Do you want to pre-render stuff and put it as sprites in the scene?
In short, yes. But there are plenty of tweaks to this technique, too :)
I`m thinking of parallax-mapped sprites (with zbuffer), so they could be used on short range distances, too, and about adding deferred (because fillrate is precious in software) shading on top of all this thing :)
Aha! I tried to open SampleBrowser (to tinker and see what happens). Thanks, then.
>> it is possible to just fork from GitHub and work on your own repository and commit back and put in the fork queue.
I`ll try, though there are 2 problems
1 - i`m not so proficient with DVCS (Git, darcs, hg), having worked last years exclusively with centralised (vs, tfs, perforce)
2 - there are also chances i won`t be satisfied with overall architecture and start tossing things around, which will cause changesets that barely could be merged back :) anyway, time will show what happens.
