Hi all,
I was asked to make some space nebula skyboxes (yes I've still to get my ass in gear and do them :)
While doing some I got sidetracked, I was wondering if they could be made within Blitz3D, then I found a kick ass library called 'libNoise' http://libnoise.sourceforge.net/ (site seems to be down for me at the moment). I've wrapped libNoise for use in Blitz3D (more on that in another thread tomorrow).
I made this prog to test how to apply the 3d noise to a cubemap. libNoise isn't meant to be used for realtime use, though the demo is and it's a little slow.
Anyways, have a mess with this (try low z values): www.tomspeed.com/nebthing2.zip
It's simply 1 ridged multi fractal procedural texture :)
w,s,a,d moves cam, and hold SPACE to bypass updating the cubemap every frame (you can tweak some values quicker while holding space!)
