Night by Betis

Good one Betis!

It renders excellently at high res too. I have my 1920x1200 background set as it and it looks even better!

I just saw it on Facebook too *fistpump*

The moon surface is almost believable! Not too shabby for a day's work!

Update Submitted!

Love that cheezeball Betis ('cause we all know the moon is made of cheese don't we?)

Reload the page!

Believe it or not I'm not satisfied 100% and I just made more changes. I'm with-holding for now and going to prefect it tomorrow and submit for (hopefully) the last time tomorrow night.

Interesting, thanks

WOW this is awesome Betis..

I just wish it didn't take so long to render...

I used your great looking filter in a new part for the Clipping article in the wiki. It shows some techniques you can use to optimize this filter greatly.

New update includes Sphinxes new awesome technique (although with all the new stuff it doesn't help too much ), Ãœberized haze effects, a sun (see picture below), atmospheric shadows from moon, resolution slider to compensate for high-res images, a more normalized darkness slider (so it's not always in the 90's), aaaand.... idk I think that's it. Sphinx I might need to you to look at it again and see if I'm doing the speed fix right or if there's more optimizations I can make before I submit.

One more

Hey Everyone,

Hi Betis,

That is SUPER COOL, I Love it!

Have a GREAT day!

Holy photon batman! Are you submitting that update?

Daytime moon

very convincing Betis

hmm that's strange, I didn't get a bug report. Basically I'm not good at making filters fast, so Sphinx is going to go in there and see if he can change my filter as little as possible and speed it up

Betis, I'm taking a deeper look at your filter construction right now - pretty tough layout - I have a question about a certain construction I see several places: before you blur something, you scale down, blur it and then scale up again.. why is that?

Ok, the gain was not as big as with the initial clipping trick, but I managed to reduce rendering time 20-30% and it should be less memory hungry for larger renderings. Note that I had to rearrange things a lot (to understand the construction) and the result is not 100% the same, it should be perceptually equal though (might need a little aesthetic tweaking).

Basically I did three major changes: replace blends with math components where possible (use Multiply instead of Blend w. multiply etc), added Lookups for constant signals to improve sample cache usage and got rid of as many blurs as possible..

I did add a few clipping threshold here and there too.

If you want the filter to render faster you need to do some essential changes, like getting rid of bombers and more logical clustering of segments.
