I extrapolated a bit Andrew's patch.
The result isn't totally what I'd like, but I'll improve it later.
In order to create nicer visuals, I'd like my glowing objects to light up that intersideral black void ..
I mean, I'd like to have plasma clouds, and other strange gas objects that would modify the light passing through them from the camera point of view
I know I miss many things here, but I'd like to know a couple of leads to follow to try to make that.
jit.gl.volume is nice but I guess I cannot create a volume around 3000x3000 OpenGL units without breaking my CPU (or the universe maybe)
So I guess there would be some tips (like create cube grids maybe, reflecting lights etc)
Anyone would push me in the good direction, here ?
Many thanks for your help
