*spin-off* Naughty Dog, SPUs, Radiosity

[ultragpu]

Maybe they can now add Dynamic Radiosity with the freed up SPUs.

Yeah I know I'm dreaming..

did they ever say they are not using it? No body knew GOW3 was using the same radiosity lighting as BF3 until DICE mentioned it.

Is this the one you're talking about? http://bf3blog.com/tag/engine/

Realtime radiosity (a dynamic light source with HDR), powered by the Enlighten middleware engine, previously used in God of War 3 for the PS3

 

[Gitaroo]

ya, or was that wrong?

Never saw any radiosity in GoW3. Not to mention Enlighten's radiosity uses static geometry for the lighting calculations, wouldn't work on completely dynamic environments like those in GoW.

But then again I could be wrong.

I think they must have used baked radiosity like Mirrors edge, they too used Enlighten middle ware to calculate and bake GI.

It has.

GoW3 doesn't use Enlighten.

You're confusing Beast with Enlighten... The latter being completely real-time dynamic radiosity solution...

I read that CCP, the developer for DUST514 has licensed Enlighten:
http://www.geomerics.com/news/dust514.html

CCP, creator of EVE Online, today announced an agreement with Epic Games China to license Unreal Engine 3 for use in the development of DUST 514. The genre-defining, console MMO First-Person Shooter is set within the same universe as EVE Online, the award-winning science-fiction MMO for the PC platform.

CCP also announced it has entered a joint development agreement with Geomerics to integrate Geomerics' Enlighten real-time radiosity lighting product with Unreal technology. Currently in development at CCP's Shanghai studio, DUST 514 is the first scheduled console game to combine the use of Enlighten with Unreal Engine 3 to produce fully dynamic lighting for console platforms.

[Blah...]

Truth to be told, I'm more concerned with the FPS gameplay compared to features like real-time radiosity.

 

[L. Scofield]

It has.

Proof?

 

[patsu]

While we are at it, what technique(s) did ND use to render the "flooding light" in the boat level corridors ?

Isn't that volumetric?

 

[patsu]

How is it different from non-volumetric lighting ? ^_^

AFAIK it calculates the light as being a transparent volume of space that allows objects to pass through and cast shadows, do sub surface scattering etc. Think of the sun shining through a window and all the motes of dust being captured in it and the way an object in that light seems to develop an aura.

That's called participating media.(meaning the air is a physical medium that can receive light )
With light occlusion.

 

[patsu]

A subset of this ?

Yeah ,exactly.
