In first CRYSIS we have the REALTIME AMBIENT OCCLUSION (screen space ambient occlusion).
In 2007 It is revolution for interactive applications, AO give good help for game developers!
What next? GI ?

For those who does not know:
---
The Ambient Occlusion it is effect which helps to see small details of geometry on 3d objects.
It shades internal edges of geometry. It works as the simplified simulation diffuse light or sky light with radius limit.
---
The realtime GI it is simulation of diffuse reflected light with color bleedings and with radius limit too.

CryENGINE3 supports screen-space global illumination, in the same way that we don't have 'proper' AO but SSAO instead.

As far as I have understood cryENGINE3 has an opportunity to display both effects simultaneously: SS AO and SS GI?

Yes, that's correct.

Yay Ruans here!!!!

um.. Nice teccy talk there :/

If "SS GI" it is possible on "PS 3" and "Xbox 360" it will be the big step to realism and better quality realtime CG on consoles.

So, if " SS GI " for consoles it is possible only in simple 3d scenes, all the same it will find wide application in the future games.

I really don't care as long as it looks good. But it probably wont be all that powerful considering the console factor

Yeah, SSGI is a cross-platform effect as far as I'm aware. Will check that one with the graphics guys.

You guys don't know what you're talking (typing) about. The textures are baked in. realtime GI isn't possible yet.

I would hope I know at least a tiny bit...

CryENGINE3 supports screen-space GI. You'd have to ask a graphics programmer for the full extent of what that implies as opposed to 'proper' GI but I can assure you the effect is very much realtime with no baking.

Sorry Ruan, I shouldn't have worded it so rudely. Can't edit with this forum setup. There must be a different definition to "real-time GI" for gaming instead of 3D software rendering.

Ehm, that would be SSGI. Look it up on wikipedia. SSGI uses a lot of tricks to make GI possible in real time. Of course, it has it cons too.

@Cry-Ruan. - Hate to say it Ruan, but these forums are pretty bad. I don't suppose it would be possible to go back to the old one until Crytek works out something better?

I agree, but unfortunately the decision has been made. All I can say is that the setup should improve with future iterations of the site.

GhostintheFlesh, we obviously can't do crazy amounts of light bounces or anything, but the end result is pretty effective for a realtime renderer.

oh crap, now I feel even worse you're crystaff. *e-foot in e-mouth. Sorry man, meant no disrespect. Thought you were another nobody.

Really not a problem.

I HAVE SEEN "SSGI" HERE:

AND THEN I HAS DECIDED TO CREATE THIS FORUM.

In these videos I have seen some attributes:
1) the GI Bounces = 0 or 1
2) GI have radius limits

These attributes is remote, are similar just as mental ray with Final Gather.
I experimented with settings FinalGather in mental ray and received similar result as on these videos above.
The miracle that "SS GI" works in real time.

it is Cascaded Light Propagation Volumes for Real-Time Indirect Illumination in CryEngine 3

Telemix. Mental Ray is a 3D renderer. CryEngine is a game engine. The GI is baked into the textures in the game engine, NOT calculated in real time.

@GhostintheFlesh: No, it isn't baked into the textures. It is calculated in real time, and thats possible because it isn't the same GI that you have in renderers like Mental Ray. It's not raytracing but its an approximation. See here: http://www.youtube.com/watch?v=vPQ3BbuYVh8

Wow. Great link Mega. I didn't think gaming was at this level yet. How they get it to do it in real time baffles me. Even without raytracing, it is still is hardware intensive to calculate light bounce like they show. The color fog towards the end is even more mind baffling to me. Effects like those hit render time. Perhaps I will use CryEngine 3 to render my 3D models with abilities like those. Sorry for doubting you Tele, just wasn't expecting gaming to this stage of ability for years. Someday they'll have raytracing, with refractions in games.
