Here Comes the Sun
------------------
A little co-op production by Raizor and NeriakX for the DBF Phenomena compo.

OpenGL and GLSL based attempt at a sun and planets with some god rays and other jazz.

Sun idea was based on an XNA tutorial by Nicolas Menzel

If you have a slow PC, you most want to disable Post Processing as this will avoid the blur and bloom shaders and speed things up a little. The smaller the FBO size, the faster the demo will run too.

The sunspots are a bit blocky and pretty GPU intensive as the original technique I was working on didn't pan out in time.

I'm using floating point textures for the sun, so if you gfx card doesn't support them, you may have issues. I'm also not falling back to plain texture copying if FBOs aren't supported, I didn't have time to get that in place. Sorry. Shaders are still not compiled into the exe either, that's still causing some issues on certain systems, so I decided to keep them external for the sake of compatibility for now.

Anyway, that's it for now, thanks :)
