Advanced realism through acclerated ray tracing

[micolsdk]

the physics has been there for centuries, we just need faster machines :)

[INeedToLiveLonger]

@micolsdk not on silicon

[pornostar100]

SEGA's Model 4 ray tracing capable hardware is currently in development

Too much echo and light. More curtains next time, please.

[pwiattitto]

yep, subtitles would have (and still would) helped, cause we want to know what he's saying.

[thekhenthul]

boring :(

[lolpalol2342]

Really i couldn't care less for Raytracing <.< i don't care if the reflection suck ass, all i want is good physics not fucking good mirror images <.< weird shit ppl focuses on in this world :S

[monkeytwineball]

Well yeah... but wouldn't it be cooler to have your physics AND your realistic graphics?

It's like saying you don't want people to grow potatoes because you like steak.

[twebb72]

Dude, ray tracing is path of light or projections on digital models; it solves a much greater set of problems that scanline rendering cannot solve (easily anyways).

Not to mention, doing something like this say 20 years ago, was completely out of the question. Its a milestone not just for gaming applications.

[lolpalol2342]

I bet that nobody cares.

[AzuMao]

Mmmm, donuts.

[Hukler]

So basically its the next step towards better lighting in games, or at least more realistic. That means Mirrors in Half-Life 6!!! and when you are under water in a game you will experience refraction as if you were in real water. Oh wait, they haven't even gotten water physics to work in games yet....

[cyborgtroy]

They could, it just takes a assload of CPU power.

[msqrt]

Ahem. Ray tracing is not only about lighting, its about all drawing. Of course the most visible changes are about lighting (refraction, reflection, very detailed shadows), but ray tracing will also increase performance a lot. The bigger the scene, the more ray tracing shines, and at some point it is faster than a traditional rasterizer. And I'd like you to know that a) Crysis and a few other games have water refraction (not physically correct i think) and b) water physics is a lot harder.

[msqrt]

And as a nice random fact, with ray tracing you can draw balls (and most simple shapes) with infinite accuracy (you can zoom in as much as you like and never see polygons)

[Capeau]

lighting = drawing in CG

All you see in the real world are rays of light. Photography does literly mean 'drawing with light'

[VCat2006]

Mirrors? GlQuake and UT99 had mirrors! The E3 Source engine demo did, too.

Wetrix had some nice dynamic waves, IIRC.

[kamonar]

Blood had mirrors lol

raytracing is a technique that determines the pixel color at the screen by casting a ray into the 3d scene to "look" where it hits an object to find out what color to use

the common technique is rastering

it determines the color for a pixel by going through all polygons in the scene and calculatig its position on the screen and then filling the pixels with the associated color of the texture of the poly. thats way faster

raytracing=starting at the "eye"

rastering=starting at the "scene"

[blahdob]

What he means is it figures out where each beam of light goes

like when it gets reflected or goes through glass

[vitorbalbio]

Raytraced is a outer technic for show the scenes 3D in screen. The actual tecnic commom used is Rastering. The Raytraced is more realistic because use phisics correct parameters for generate the imagens on the screen but it is so slow

[Aardcore]

Holy crap SUPER VOXELS BAHAHAH! 3DFX would be proud of such progress -- and it's not ATI or even nVidia behind this-- that's CRAZY

[Hikayuhuy]

with that being said , how are you gonna put a bluray disc in it ? the more you think about it , the less it makes .a ps3 is console and it WILL eventually obsolete but the technology it packs is so advance that until now , you cant get a better deal . im not saying it's bad , im just saying that for a entertainment powerhouse and gaming platform (no RTS tho , pc is the king of RTS) ps3 is a better platform .if you have a lot of money , pc is the way to go.

[Drunkenvalley]

Frankly the PS3 is still way too expensive; at least here in Norway. :|

Particularly considering that while it's getting better, the PS3 still lacks content that truly justifies the purchase.

[drakio99]

A GeForce 9800 GX2 has 256 strem processors and it has 2 cores//...

[cyborgtroy]

Unfortunately, raytracing requires more of the branching and logical instructions than just straight math. Of course, it does require a lot more power overall, too.

Graphics cards will need to be redesigned a bit to do it well, but I can see it happening.

[RalenSanis]

Ray Tracing will moer probably will be able to work with an Intel Larrabee, a 64 Cores Proc ( 2010 is near^^) willbe better for Ray Tracing than a GPU

[McTDEUCE]

It takes 3 Ps3 to render just 1 car. All i can imagine is that the ps3 will blow up if it tried to render that.

[viewer949]

Thats why you don't get a PS3. Thats why you get a $500 computer (which can pwn the PS3), hook it up to your HDTV, then plugin a controller (wii, 360, PS3 controller or use the good old fashioned) then game away! Its only the thought that its not a console which makes it not attractive.

[Hikayuhuy]

wow , a console hater and a dumbass pc fanboy . tell me , how do you build a pc that can run crysis ( which have as good graphic as MGS4 ) at very high level with decent frame rate and keep it below 500$ .a gtx280 cost at least 450$ or 4870X2 500$. i would love to buy the damn computer that run crysis on very high with 20fps off you for 1000$ if it's even possible in the next 6months. i you cant , shut the hell up and stop comparing . geez .

[imsososogreat]

yer pcs r more expensive, but that dosnt mean they are worse

[Hikayuhuy]

i've never said they are worse ? they're the best if you know how to invest in pcs .but , it would cost around 1000$ bucks at least to built a pc to catch up with games in the next 1-2 years or so . anyway , im building a new pc , pretty awesome so far .GTX 285 .. wooot , im out of money T_T . cant buy game for the next 2 months .

[imsososogreat]

lol yer...

im pretty cheap tho, got 8800gtx not that bad

[cyborgtroy]

All the amazing graphics features, like shadowing, reflections, and even natures!

[airraideagle]

Intel's upcoming stab at the graphics market, known as Larrabee, for 2010, will be very interesting. It'll have 16 to 24 cores (maybe 32 cores in future versions) plus some fixed-function hardware for textures.

For doing ray tracing graphics on a CPU, Larrabee should blow away what can be done on an 8-core system and CELL. Larrabee will compete with Nvidia's next-gen GPU architecture (I mean the next major GPU beyond the upcoming GT200) and AMD's Fusion family.

[Dangle24]

Larrabee project is for GPU mate so basicly 16 core's for a graphics card is prettey low the GeForce9800 GX2 has 256 core's

[ish718]

Hes not talking about the same kind of cores

[Subtalvik2]

Ps4 will probably use ray tracing, seeing how far we are already.

[doverman2]

ps4 will definately use some sort of ray tracing for sure cus software renderers may be coming back.

[girlsdrinkfeck]

that dependws which way hardware goes , if intel gets its way the future is gpgpu not cpu calculated graphics

[doverman2]

agree cus at this point intel doesn't have anything to prove that this will be successfull

[girlsdrinkfeck]

yup , cas even the ps3 struggles to make advanced graphics with the modified 7800 and the cell

[JEWDOOMAGIK94]

have u ever seen any ps3 ray tracing videos??? i doesnt strugglle at all and when it ray traces its only the cell processor. it doesnt even use the rsx to make those graphics. Imagine the graphics capabilites when it uses its ray tracing abilities with the cell processor and RSX.

[girlsdrinkfeck]

so ?i seen 8 year old games with raytracing on the PC , its not new and not special

[JEWDOOMAGIK94]

PS3 not PC

[girlsdrinkfeck]

PC came first

[JEWDOOMAGIK94]

yeah no shit

[Tomahawk1505]

i think not

[Greyh0und]

THAT my friend, is ray CASTING...

not ray TRACING...

ray casting is used in wolfenstein 3D etc.

[girlsdrinkfeck]

i dont care

[girlsdrinkfeck]

also your wrong , i mean ray tracing , quake 2/3 has been modified to use ray tracing , and its a old game

[Demoras]

Yes. Raycasting was used in Wolfenstein 3D. And your point is...?

Raycasting is a pseudo 3D rendering method. That means it's not 3D but in fact 2D. This technique is no longer used.

What you see in the video is raytracing. It's a completely different technique and is very cpu intensive, because raytracing precisely calculates every pixel on the screen.

[TheSleazySaint]

Yeah that was used for old Qbasic games.

[mygaffer]

Haha, idiot

[Danny77uk]

FAIL

[cyborgtroy]

Does that look like Wolf3d?

[airraideagle]

PS4 will probably use some form of hybrid rendering. A combination of rasterization and ray-tracing.

I think the question is, what ratio or mix of ray-tracing and rasterization?

[doverman2]

totally agree with you that was what i was tryin to say the whole time hybrid rendering of raster/RT will dominate next 2010.

[madmax10101]

wow! :D

[doverman2]

the thing bout raster graphics is that they lack lighting and shadow realism. look at crysis or killzone 2, just imagine a game 20x better than that especially when it is being used by the movie industry. though its hard to tell when its possible cus of the lack of hardware memory. lets say end of 2008 or start of 2009-2010 which is what intel and nvidia marked.

[Droyd21]

What do you mean by raster graphics? graphics made out of pixels?

Honestly I don't find this raytracing stuff that exciting. Imho, pixelshading is more or less covering up what is not possible with current hardware, and you could do reasonable (and a hell of a lot cheaper!) effects that -resemble- raytracing. Not the real thing, but relatively close, and more affordable.

Well obviously raytracing will make it to the gaming industry but for endusers it won't be this "giant step"

[doverman2]

i agree but what i mean really is that a fusion or hybrid of gpu and cpu can really improve ray tracing in games. such that reflection and refraction can be viewable in gpu. there is OpenRt which will be like opengl but i think RT will be interactive in 2009 or 10. hardware and memory bandwhich increase will enable RT. it certainly not a giant leap in graphics but it would be still helpfull.

[gangstermailuser]

True. In a few years when hardware becomes better and cheaper, real-time raytracing will be possible on affordable PCs. Raytracing provides more satisfying results than pixel shading because instead of just shading, it follows each ray of light for pinpoint accuracy with light effects like refraction, reflection, shadowing, etc. Raytracing is really just light physics calculations though. It will be like ragdoll physics now; it's easy to do now, but years ago it was just a dream.

[doverman2]

exactly my point i strongly believe that this and radiosity well radiosity has become a reality already with the new enlighten engine by geomerics, but ray tracing is a more efficient way to render games and plus the amount of cores acceleration is widely helping. it is already the 21st century so might as well give it a shot.

[zytekfan]

It will be a long time before ray tracing is used by the gaming industry...

[djphatd]

why?

[doverman2]

ray tracing will kill rasterization thats if it can go real time smoothly with upcoming monster hardware
