i was just thinking of hair physics in games just moments ago!!
brought up by disney pixar's brave. i heard it took years to develop the program that dealt with it tho

look at the protagonist's hair

WTF neoseeker? First nVidia now it's AMD, make your mind!

Sorry folk. I didn't drink my coffee this morning and totally wrote the article about Nvidia initially. It's quite clearly an announcement from AMD. No idea why I made such an odd association.

Should be fixed, and by all means let me know if there are any errors and I'll fix them immediately. Tech isn't my specialty, obviously. No excuses though. Pretty big, dumb mistake and I apologize for it.

Just imagine all the glorious hair pieces in future RPG's running this *drools*

Finally(AND THE ROCK MEANS FINALLY!) tech that'll do Leon's magnificent hair justice.

I must say. AMD are just opposing all of Nvidias benefits now. AMD were your go to for cheap good performance cards. Nvidia had the same sort of idea - costing a bit more, and they had A LOT of better technologies making them more worth while if you have the extra cash. Now these guys just have to make the decisions harder XD

Seems like a pretty logical mistake considering NVIDIA released their own hair demos not too long ago and AMD rarely markets its tech demonstrations Glad to see them stepping up now that they're basically championing next gen.

NVIDIA has always had fancy tech but realistically its never been implemented into a significant enough amount of titles in a meaningful way that would merit thought in a purchase. Just go for whoevers offering the best performance/price, although AMD might be stepping ahead if they optimise console games for their cards.

Thought this article was brilliant until I realised it was serious.

Hair graphics, really?

^ It's... one of the most difficult things to animate believably. Hair.

^^and it has implications for all forms of particle physics and rendering

The hair will have more polygons than the actual entity is how I'm reading this.

Kaindog Aren't you willing to trade 5-10 FPS for beautiful hair?

It's not.. that complicated on the high level. When you can use complex math (past shader logic), you can have fairly complex models and wave-simulations running on the object collections - but only render the visible parts. And not - for example - the individual strands of hairs, with particle physics pushing each strand back and forth, and so on.

Because that would be extremely heavy. Even if updating or "flexing" strands of hairs in the mesh/model isn't actually that expensive.

It's similar to the way the fur was done in Shadow of The Colossus, or the fur we were kind of expecting in The Last Guardian. Same principle they use in WipeoutHD and GT5 (much more complex models in the game than what's rendered - the rendered detail is dynamic, adjusted to what the rasterizer actually can complete.. GT5 has a few physics details that are much more complex than what you can do with directcompute every frame as well..).

The irony is that the level of this is pretty low compared to what could have been made on the ps3.
