nv30 - Photorealism?

[KimB]

Supposedly, the FF movie demo was running at around 15 fps with many effects turned down (and lower-poly models). nVidia has stated that they will be able to run the movie in real-time with all effects on by the end of the year (though I'm sure they don't mean with movie-quality resolution/FSAA and motion blur...).

Still, if the NV30 is flexible enough to do every effect that is currently used in professional 3D rendering (except radiosity lighting, of course...), then it is conceivable that arrays of NV30's could be used to drastically reduce the amount of time required to render a movie. This may be a reason for nVidia to pursue 8-way or more combinations of NV30's for very high-end rendering.

The collage I posted yesterday was sent in by a visitor who said it was publicly available. But I have yet to hear back from him when I asked for the URL.

Yea, first post the stuff, then check it's authenticy. Very good journalism.

I normally don't operate that way, but if I fail to hear back from the visitor who sent me the image, then consider this an advanced apology.

No go beat up on the Inquirer.

I bet that collage is a collage of real demo pics from demos that Nvidia did by converting existing 3D scenes they could get from the net.

I bet not: Why on earth should this collage hit the internet [from nVidia] before their NV30/Cg PR-lanch? It doesn't make any sense, so I'm voting for a nice fake (although they may actually be able to do something like this in real-time of course).

Why on Earth would NVidia show a NV30 rendered image in the Cg powerpoint that they released!?

A friend of mine told me that the collage was from an Nvidia investors meeting and the powerpoint collage was used to talk about the upcoming rendering quality they are shooting for.

First you accuse NVnews of fakery (I mean, that's a pretty mean accusation, they they forge images and then link to them as news stories? Secondly, the image looks like past NVidia collages from their demos. If its a fake job, it's a pretty good one. Third, the images are nothing special that can't be done on a GF4/ATi8500 today at a very slow framerare. Are you gonna eat your words like Doomtrooper had to eat his over the E3 "bet"?

Why you people think these images require raytracing or global illumination is beyond me. They are easily done by RenderMan/PRMan as shaders with no need for radiosity or raytracing. I see nothing that precludes these images from being NV30 screen caps. They could be at 10 frames per second, but they could still be from actual hardware.

democoder , so you think we'll see kaya as a realtime project soon ? like this fall ? maybe à la doom 3

there's also a lot of blur on that picture and i'm not talking about the backdrop , i'm talking about her face , if it wasn't for it , i'm sure it wouldn't look as good

apart from her i think the other pictures in that "collage" can be done in real-time right now

but for kaya
I'm thinking fall next year ... maybe with some sub-pixel precision

The guy behind Kaya specifically stated he used raytracing. However, IMHO, the NV30 should be able to pull of something extremely close to that in realtime.

there's also a lot of blur on that picture

More than likely due to the picture being resampled to a smaller size. These look much better:

no no it's intentional , makes everything look smoother, and hides modeling/texturing flaws

A friend of mine told me that the collage was from an Nvidia investors meeting and the powerpoint collage was used to talk about the upcoming rendering quality they are shooting for.

In that case I'm really sorry about calling it a "fake".

This is, however, the first info that links the collage to nVidia. It just popped out of the blue on nvnews without a source so that was the reason I questioned whether it was authentic.

But now I stand corrected. Thanks...
