Terrain self-shadowing preview
« on: April 26, 2012, 11:01:46 am »

Here are couple of images with terrain self-shadowing in action.







There are still several issues and bugs to solve before it can be made public though, as it doesn't work in all conditions yet. I've selected only the nice ones :)

It is not just better, it almost changes the whole thing! Now it gives me the motivation to do an other time-lapse video.
Congratulations, Cameni.

how easy would it be for you to add in shadow PCSS? was gonna ask if you could release the uncompiled shaders so i could have a look myself but seeing as how your messing with them atm here's the link for the shader source...http://developer.download.nvidia.com/shaderlibrary/webpages/shader_library.html#shadow_PCSS

Does it block the sun haze that appears through the mountains? Like this.

Amazing! Great update. The self-shadowing looks pretty cool!

Not yet, it's one of the things that need to be fixed.

Does it also have issues with really acute angles of the sun?
I tried some terrain self shadowing and remember having huge problems when the sun approaches the horizon!

Yeah !
Quick questions :

How much is it affecting framerate ?
Do you plan to add soft shadows ?

We didn't make any measurements yet, as the algorithm is going to change, to fix glitches, expand the range. It should speed it up as well.

Acute angles - the light gains darker orange colors, contrast is lower, so the errors are less visible even though that case can be problematic. But it's too soon to tell too.

A bit off topic and I know there isn't actually a real sun in there yet, but is the optical illusion that causes the sun/moon to look larger at the horizon be doable?  And would it be an actual optical illusion or just making the sun physically larger when it's at the horizon?

I logged in this afternoon, and missed this thread completely.  Log in now to clean up the unread posts icons, and kick myself in the behind for missing it entirely.

Holy cow, that's gorgeous :)  I can't wait!

Well, since the illusion is in your brain, it should work without us doing anything, as long as there are accompanying details near the horizon that make up for it. I personally never noticed Moon being extra larger, except in Hollywood movies and infected games. We won't.
