AMD reveals what ‘TressFX’ is: a very cool-looking new hair rendering system

Tomb Raider TressFX

By on February 27, 2013 at 5:23 pm

Yesterday’s tease from AMD promised a revolution in PC gaming realism, and AMD have delivered… a new hair-rendering system. Sounds weird? It actually looks super impressive, and AMD are debuting it in the PC version of Tomb Raider. Don’t worry though, it’ll work on NVIDIA cards as well — all DX11 cards will be supported.

“TressFX Hair revolutionizes Lara Croft’s locks by using the DirectCompute programming language to unlock the massively-parallel processing capabilities of the Graphics Core Next architecture, enabling image quality previously restricted to pre-rendered images,” reads AMD’s announcement. “Building on AMD’s previous work on Order Independent Transparency (OIT), this method makes use of Per-Pixel Linked-List (PPLL) data structures to manage rendering complexity and memory usage.”

Check out the before-and-after pictures below for some promising comparisons (click for larger).

Pretty sweet, will be intersting to see if the physics works as god intended when it comes out as well.

 

It’s rad that it works on nvidia cards too. Nvidia need to try and get a deal going for physx on ATI.

 

I’d like to see some video of that in action. Yes the screens look good but it doesn’t really show enough, what it looks like in motion is more important.

 

Makes her hair look far too clean imo

Me too – comes out march 5, so not long now. I wonder if it’s in any of their trailers already?

Agreed. Looks nice but a bit out of context. Wonder if there is a grease modifier? :P

 

Good guy AMD, not being a d!ck over who can use their graphics technologies. Hopefully this tech gets widespread use showing nVidia that if they would open up PhysX more studios would use it.

 

If it works on Nvidia cards its got nothing to do with AMD cards its just code, yes you made it well done dont say we need a AMD card to get it to run, back to Nvidia and wait for their Pantene attempt.

 

Um, hands up if you also cant tell the difference :)

Reminds me of those old HD tv adds

“This is what your TV looks like now”

*shows random scene*

“And this is what it would look like on a HD TV”

*shows the exact same scene*

Maybe those looked different if you alreay owned a HD tv, but i doubt it :)

 

coatsy22,

Were you looking at those comparisons on a potato? There is quite a big and very noticeable difference.

No one said it did – it’s just that AMD have done the R&D on this tech.

It would be great, however unlike this hair tech, physx requires actual hardware to run, so ATI would have to change their cards as opposed to Nvidia just letting them run it.

 

elliotengi,

Not really. You can already get the CPU to run PhysX it just runs like poop because CPU’s aren’t powerful enough. I would imagine only driver level optimizations would be needed to get PhysX running on AMD video cards.

 

coatsy22,

Yeah I remember ads like that. Only thing was I was watching those ads on an older def TV so of course there wasn’t any difference. Silly ads really when you think about it.

 

The hair song popped into my head while reading this

Yeah, I’m really interested to know what it can do when introducing a games environment into it – such as getting wet, or dynamic modification (fire).

Additionally… please, please PLEASE let this be adapted to things like foliage and trees. That would be so awesome.

 

aphyosis:

I agree. Cool technology but not the right demo for it

 

elliotengi,

It is a pity GoN missed the best quote of the lot: “We don’t create features that lock out other vendors.”

And that, folks, is why I am in bed with AMD…

 

Woop, wont have to sell off my 690 now. :>

Just ordered a 7870 for my mini-itx build as well, so I’ll be getting Tomb Raider and Bioshock Infinite for free! :D

 

Hopefully it’s a bit less clean looking in motion. I really hope they tweak it to just be a bit less reflective, if nothing else. Real hair only looks like that in studio lighting.

Key words being “real hair’ :p

You’re right about the cpu thing, but I’m incredulously doubtful that driver optimizations would get it running on ati without hardware modification and or radically re-written code.

I think you’re wrong, but you might be right.
