Atmospheric scattering

Sign in to follow this  


Hey guys, glad to be programming and posting again!

I have something to show too. Yay. I've been studying atmospheric scattering. I'm actually writing my senior paper on it, so I'll be looking at different implementations all semester. Over the past couple days I implemented Preetham's introduced in "A Practical Analytic Model for Daylight." It's a very easy one to implement, and hard to get looking right. But still, I've impressed my friends with these pictures:

If I was to seriously use this it would require a ton of tweaking. But I'm off to study other implementations because 1) this one sucks to be honest and 2) I need to for my paper anyway.

You can track my progress here:
