Please stop using services that limit download speeds and ask to pay money. That's seriously annoying. Try something like Mediafire or even a mirror site with unlimited bandwidth.

OK, Makes sense. Still great work though!

nate, no it is GLSL (OpenGL Shading Language), based on C programming language.

Thanks, guys!

Im really sorry if the second link caused any problems, it somehow got infected in Filedropper.com servers after uploading it. Now looks like all filedropper.com files are deleted.

here is another link to blend file hosted in trusted server ;)

@nate
there are a lot of values that can be tweaked inside the codes for better performance/lower visual quality. For light Scattering, try lowering the NUM_SAMPLES value. Anyways, unless the downsampling gets integrated in BGE, the 2D Filters like bloom or blur will always be slow.

@Stamen
no not at the moment, but someone who is more experienced in coding, could hardcode it in Blender and make a SVN build.

@Thomas
This demo requires powerful system to run properly, also there is incompatibility with ATI graphics cards at the moment, im not sure why.

This is just plain awesome. I have some problems with it though.
1. I have to move the little plane on the camera to see anything, although I don't have to for an actual render.
2. All I get is very white/greyish color, and close to 50 fps.
3. When I press 4, Blender crashes.
5. In a render, the moon's plane stands out instead of blending in with everything.
6. I can't resize or split views.
Renders do look great, and take a surprisingly short amount of time.
I don't know if my problems are just from lack of good hardware, or from the OS, but my hardware is:
AMD Athlon XP 1.4GHz 1GB DDR RAM
ATI Alli-in-Wonder Video 128mb
Running Windows 2000
(I would have something better, but this is my brother''s computer.)
My guess is that either my card doesn't support something, or Win2000 is causing problems.
I'm using 2.48.
No SVN or anything.
