ATi Ray-Tracing....

ok, very interesting article, and those pics are simply inSANE. i want to see that in motion please (the one where ruby is in city traffic)

All those Transformers teaser trailers were rendered on a GPU and - more importantly - directed in real-time. The producer of these trailers had complete freedom to play around with a "virtual lens" and direct the trailer in his own way. The Radeon 3800 series brought some improvements and Urbach promises new demonstrations for this year’s Siggraph conference, including a complete Ruby demo

ok, that is just sick! how come i cant play crysis at max at that resolution? and crysis doesn't look THAT good either :p

EDIT: bad quality on the toob, but still makes me wanna go and buy ATI hardware

EDIT: a toob vid of some nutters doing the same thing on a simple (one car) ray tracing demo using THREE PS3's

please note, ATI does this with a GPU :p but i dunno the rest of the details

Oh i get it!
Wowowow i hope games are like that quality in the near future!
Hahaha i thought those were all real pictures
 
hehe, yeah raytracing is very cool, it is photo realistic in theory, and all it is, is well maths, we did a ray-tracing project at varsity once.

You basically calculate the refraction and reflection of light beams from the light source (or multiple light sources) against all the objects in the scene, the amount of recursion, ie "bounces" of light against the object translates into accuracy and thus quality of the image. There are also physical systems being modelled in some applications, like energy of the light source and surface material, diffuse specular, and type of light source spot, ambiant.. etc each with its own formula for refraction and reflection...

Very nice to play around with povray, and do some stuff on you current hardware these look pretty amazing... It is just computationally complex, and it grows in complexity with the amount of objects light sources and recursion, or light ray "bounces"

Did I mention how cool it looks :p

So the nice thing about this tech from ATI is, that you can do raytracing processing on the GPU which we all know will whip a cpu at vector processing 40 - love...

If we can obtain realtime fast 60fps ray tracing, GFX nirvana!!!

Radeon 3870, the test scene jumped to 60 fps, with a drop to 20 fps when the proprietary Anti-Aliasing algorithm was applied. Urbach mentioned that the Radeon 4870 hits the same 60 fps – and stays at that level with Anti-Aliasing (a ray-tracer is not expecting more than 60 fps.) JulesWorld’s technology also works on Nvidia GeForce 8800 cards and above, but the lack of a tessellation unit causes a bit more work on the ray-tracer side.

ehehe kwl hey

Now what got me all excited was with 3000 series u get 60fps with no AA, and 20fps with AA. 4000 series..... 60fps with no AA, 60fps with AA

That just shows that the RV770 has got some serious AA power. I cant wait to see how the RV700 (4870X2) will do at Farcry 2 and so on when all that comes round :rolleyes:

Omw can you imagine playing games like FEAR and STALKER? O M W itle give you nightmares
