I read the description (I think), saw the screenshots, watched the videos, browsed the discussions/blogs, subscribed/follow updates, etc and the only thing I can come up with on what it actually is, is just a couple of descriptions of what it can do.
I-Novae Engine can procedurally generate planets, galaxies, and universes in 3D and run/view them in real time without the need of loading screens to transition between large spaces. It can also render these graphics alongside other models with appropriate lighting. I also read a post from another user here that it does some kind of physics, but I don’t know how much/what kind or anything about that.
Is that everything? [Planet generation/Universe generation/rendering/physics]
Is it it’s own game engine, allowing you to create whatever you want within the system’s capabilities (such as in other game engines like unreal/unity/etc), or is it just a library/plugin/extension kind of thing that handles these 3d elements, but utilizes another engine for the game itself?
