Nvidia's Quadro line is unmatched, but WTH is with the ray tracing images from 1998???

1998?

The Toyota IQ is from 2008.

None of this stuff is new, the design team I work with has produced stuff like this for quite some time. Though newer computers have seriously sped up the rendering process they still take ages.

If we can speed it up even more and add even more realism, I'm all for it.

[SubZero.it]

Try to understand my point m8. If we can't achieve that quality of ray tracing in real time, then we shouldn't be focusing on it until we get there.

In the near future, real time radiosity and character lighting is what will power games towards realism: http://geomerics.com/enlighten-media.htm#gdc08-demo

Then there's the first time we'll see real time global illumination in Cryengine 3 coming 2010: http://www.incrysis.com/index.php?op...sk=view&id=797

I wouldn't take cryengine as example...they could introduce something new of course,but where are the performance??Will be less optimized that the last engine.The evolution of an engine should be like the source have done that time,quality and PERFORMANCE...so good luck

goddamn whats wrong with people on this forum, the second ATI manages to get near parity they own the gpu market by every measure allova sudden.

When I said "I'm pretty sure", I didn't mean it as "I heard the other day", I meant it as "I'm pretty sure":

Looking at the big picture level, we don't see any sweeping or major performance improvements from this new hardware. Nevertheless, this latest ATI offering makes a very good showing against the Quadro FX 5600, our previous performance champion. Given all of these observations, the pricing on this card ($1,400) makes it a very good deal for the money, even though a lot of money is involved. By way of comparison, the recently released Nvidia Quadro FX 5800 goes for an astounding $3,150, and the FX 5600 at $2,700 isn't exactly cheap either.

That's why we can recommend the ATI FirePro V8700 as an ideal product for demanding all-around graphics professionals, without any doubts or hesitation whatsoever.

Wait so, that picture is fake right? The ice looks fake. Or am I missing something how does this work?

The picture is computer generated, if that's what your asking. Basically Ray tracing simulates how light and textures are and work in real life. It's always going to look better than anything you'll see in modern games.

[dinos22]

wow those stones look so real

i dont like the wine glass shot because it's not realistic in sense that there is no way you will have a superclean glass after drinking from it. All the glass is too clean heheh

it looks awesome though

good to see nvidia doing something about this as well.....it can only be good to have them competitive in wake of intel getting into the game now

[randomizer]

i can post cool ray tracing pictures too. GPU ray tracing has an advantage over linux farms that movies use. this isnt just for real time.

Something about those rocks just doesn't look right.

[GAR]

Man, i dream of the day we can play a game with RayTracing

[George_o/c]

Wow, both the glass and the stones pictures look so real. But the second one won me over, literally ! Is it obvious ?

[GTSRboy]

How do you get pics like that? Is there a rendering program that does this?

Try this -> http://www.povray.org/

That pebbles is one of the rendered pics in the povray hall of fame -> http://hof.povray.org/ , quote -> "took 4.5 days to render on an Athlon 5600+"

This one is from year 2000 ...

[Chumbucket843]

you do realize some guy did that on his computer. its either the textures or too much ambient occlusion that makes it look fake.

[Manicdan]

i think its the shadows under the rocks and the way they are resting on each other, a few look like they would have shifted

[randomizer]

It's definitely something with the shadows or AO.

Yeah, let's stop developing technology just cause it can't work for games yet. The aliens will eventually come and teach us everything There are people who use raytracing for professional non-real time renders man, GPU acceleration would be welcomed with open arms. But really, how do we get raytraced games in the future if we don't focus on it now - magic?

[perkam]

There are people who use raytracing for professional non-real time renders man

Which is my point

There is no purpose to a real time ray tracing renderer that does work of that quality as posted by Nvidia, if non-real time renders look this:



Non-Real time renders are here to stay and you don't need a rocket scientist to tell you that up till the point where real time renders can get to within shooting range of stuff like the image above, real time renderers will be useless.

This is why real time radiosity, character lighting and global illumination are what will be important till then.

Perkam

[trinibwoy]

You realize you can use any tracer to do non-real time as well right? The goal is higher performance, the "real-time" stuff is just marketing hype. The point is to render a frame in minutes instead of hours.

[saaya]

mhhh idk... even if nvidias raytracing tool/engine doesnt look as good as "propper" raytracing... if it can be done at 60fps... thats still great.
it still beats non raytraced image quality, and with one or two generations ahead im sure they will look the same as what perkam posted.

its kinda weird though how involved nvidia is getting in actual game development and application development...
first they got involved in third party engine and game development with the twimtbp programme, then they wrote parts of the code for third party cuda tools to increase the amount of cuda apps avvailable, and now they are writing parts of code for third party game engines and games... i wonder if nvidia will end up writing their own game engine or buy the UT4 engine or something like that...

anyways, if game developers would focus on whats possible with the latest rasterization hardware, then we would be pretty close to some of the images posted here...
the problem is that almost everybody wants to write a game that can run on all or most of the pcs out there these days... so im rather sceptical about how fast this raytracing engine/tool from nvidia will actually be used... by the time it could take off, there will be larrabee out which supports "propper" raytracing...

its a smart move from nvidia though, if they can get close to the raytracing image quality larrabee can produce, but their tool is partly based on rasterization which every developer is used to, and its easy to code for this engine/tool, then that will steal a lot of dev support away from intel...
smart move... but yeah, lets see it in action first before we get excited, this might be pure marketing and nvidia might have nothing on their hands besides a nice ppt file

Damn it, now I'm addicted to this

I remember this picture from early 2000's. It was my wallpaper for a long time. There is no way that picture is from today (unless I am missing your point).

his point was that the raytracing shots nvidia showed look notably more simple than anything "propper" raytracing can deliver...

and i agree on that, but like i said, it still beats conventional rasterized games we have atm, and it even beats all previews of eye candy games ive seen that will come out soon...

[Calmatory]

The nice thing about Ray tracing is that the image quality gets better and better by the time it gets rendered(*). This means, that:

* with lower FPS one can have better graphics,
* with faster hardware one can have better graphics without sacrificing FPS
* People can adjust their graphics/FPS ratio themselves.

So, if you have set the FPS limit to 40, it will be constant. The only thing which changes from scene to scene is the graphics accuracy. It can be blurred, it can be without proper reflections and effect etc. Then, get a new CPU and GPU and you can get better graphics with same FPS OR increase FPS at the expense of better graphics.

THere is one downside with RT though; resolution scaling. Going from 320x240 to 640x480 means 4 times the rendering time. Same with 800x600 to 1600x1200. When the resolution "doubles", the amount it takes to render the scene increases by 4 times. Hence there is no way one will be playing with RT at 2560x1600 at least in the next 10 years, I'd say. ...unless the graphics will be sacrificed.

*: This depends on the engine though. It IS possible to make such engine, and some already exist.

[trinibwoy]

800x600 -> 1600x1200 is a 4x change in resolution not a doubling. But yes the raytracing algorithm is much, much simpler than rasterization. So it's great for scaling across multiple processors and it makes realistic lighting a piece of cake. But there's stuff that rastrization is better/faster at, like casting the first ray into the scene and rendering particle systems. Also there's no MSAA with raytracing, it's all supersampling for yet another huge hit.

the image you show is made in 2006 do . Even do it is quite a stunning image, I still feel it isn’t to hard to see the deferens between what is a real live foto and a image that is rendered (traced) on a computer.

Official site of source image


I think that it will be at least another 5 computer generations before we can start to think about ray tracing in real time. We still need a lot more computer power to even attempt something like that.

[ownage]

All crap!

Ingame raytracing is much more important.
DX10 screenshots looked also uber-realistic. We haven't seen a realistic DX10 game yet.
