With so little to look at, this was way too slow for my taste.

three stars.

Atmospheric scattering and supernice clouds! Some of the nicest audio in the compo too.

nice and relaxing

Being normally a fan of your stuff, this is really too slow and reminds me more on procedural 4k gfx. The last city scene with moving shadows was ace, though.

The final version is here!

Sources will also be released within a few days

I kind of liked the way the party version ended (fading into overexposed white) a bit more, but otherwise the difference was worth releasing the final as a separate product. This is what a few more days of concentrated effort can do to a demo.

Those cloud and atmosphere effects are pretty awesome! The details in the city (such as the roughness variation for the moving lights) are pretty nice too, but overall I think the city isn't so convincing and could have done with more large-scale variation.

Just published sources for this thing: https://github.com/w23/jetlag_appear. I hope somebody might find it useful.

@Provod: What theory did you based the scattering effect on? Preetham? Or something else?

love the bladerunner influences

@fizzer: scattering here is mostly based on Egor Yusov's GPU Pro 5 article "High Performance Outdoor Light Scattering Using Epipolar Sampling" with the epipolar thing completely disregarded. He lists a lot of references in Previous Work section, several Preetham publications included. He also have a few public slides available that looks very close to this.

I've also either misunderstood a few things in this rather short article, or it was incomplete (or had typos), so I went through all the scattering integrals myself (while being on a plane from Moscow to Frankfurt :D) and came up with a model that looks a bit smaller and simpler than original. I haven't compared them, so I'm not sure whether it's any different or even correct. It looks okay I guess.

If you're interested, I could come up with a short write-up on this scattering model, how it works, and how it is implemented in shaders.

Thanks. A write-up would be awesome. =)

Forgotten thumb. Super ace rendering!

for efforts (and article). It has very nice effect, but too long prelude before it.

What everybody said :) , plus I really enjoyed the transparent cars :D

... and +1 for the write-up, although I disagree with your conclusion ;)

Nice, first 4k intro by Jetlag as a group just saw the Final on MDT9k
Nice big city with a bunch of apartments and a cool street

Technique-wise pretty much what I had in mind when planning to do a sunrise intro :D Love it & thanks for the source!

Thumb! Cool light-effects!
