The Nebula Device. Another Excellent Cross Platform Engine under flexible license. This engine has a very friendly scripting interface in TCL, but also supports Python. As is the case above, Nebula is primarily a realtime 3D engine, but is low level enough for you to be able to build unique projects around it's offerings. The scene management is easy and clean and the engine is extremely fast (we tested on Linux). The community is very active and Nebula has been used in several commercial games. Used to make the art game fijuu.We advise you use Nebula1(CVS version) while Nebula2 is being ironed out.
Thanks Julian :)
