Endless City is a new tech-demo by NVIDIA for the launch of the new GeForce GTX 580. This is a Direct3D 11 demo with tessellation…
Let the machines take over!

Our Endless City demo starts with a few dozen building blocks and uses an L-System to assemble these into complex structures, buildings, whole city blocks, and finally a sprawling and boundless megalopolis.

• Tessellation enables a continuous ramp on the level of detail, more than doubling the total triangle count and providing up to a 500x increase in detail on the nearest objects.
• Three dimensional displacement maps allow greater detail than simple height maps.
• The demo positions and renders over 600 million triangles per second with a single GPU.
• The city is procedurally generated. The buildings are constructed from a small set of objects into a city of complex structures using a set of rules called an L-system.
• In the area surrounding the viewer, over a million meshes are arranged by the L-system, including roughly 500,000 light sources.

Reminds me of something....

A blade runner style cityscape light source demo featuring tesselation....

Oh yeah, that!

Demo rip off. BLATANT.

aww.. only runs on nvidia.. any hack to run on ati ? :)

I hope you're kidding... these things take 6 months to a year to put together. No way they did or could've known the themes would be similar. Besides, how they build the cities is very different. Amd uses static models while nvidias is procedurally generated from pieces with rules defining what can be paired with what.

If nvidia had done a day city scene you'd say they were ripping off the 5870 ruby/robot demo. So I guess AMD owns all things city-related for demos?

Thank you for being the voice of reason, his outrage is total bull:banana::banana::banana::banana: and reactions like his are the reason why we have flamewars.

Any chance you like AMD products??:rofl:

wires frame is so dense it's white with out textures added yet. lol

That's a bright idea of NVIDIA! There are no games for GTX580, so let's roll out ahh tech demo.^__^
Anyway Im gonna give it a try right away.

The actual Youtube video embedded in the article (link here for reference) dates back to early October during GTC, so I'm not actually sure it has much to do with the GTX 580. Still, fairly cool demo.

Dang, how about they put their effort in making a real game for once. :D

I think someone mentioned it uses Cuda for something, so no.

Exactly stupid useless demos :down:

I don't think it benefits from SLI right now, at least in current drivers.

580 is also alluded to here, along with them showing another demo called Aliens vs. Triangles: http://www.youtube.com/watch?v=oCPMHIDpT88

All 3 cards were working at 90+% so may be they do?

Apparently they are doing it with Crysis 2, but people are outraged over that as well. :rolleyes:

Whoa, that's insane.

it's already "one card - one game" generations for several years.:shakes:

Too bad it doesn't run on ATI. But that's usually the case for Tech-demos, isn't it?

TBH i think that these screenshots look like crap...

but the tesselation work is impressive (however i don't think that it's more effective than the traditional method at this scale)

Actually demo does not look that good in normal flyby mode.
Its glitchy in the beginning and very choppy and does not look good. Its only when wireframe is enabled you see how much work is actually done. But all that work does not make this look that spectacular. AMD demos were more visually appealing.

With all due respect to the work being done, this looks like 90s Scifi.

Horrible shading, horrible colors, detailing that looks way too consistent (they might want to change how they populate their L-systems).
Sounds like a rushjob as a normal scene demo will take way more time to model/animate/detail. But that won't look like monster puke.

I don't like the way it looks either. I can see what they were going for, but the effect isn't that great. I'm not impressed. The Unigine Heaven Benchmark shows off Tessellation better than this demo. :down:

Looks good, thanks for the pics! :up:
Hope we will see a similar tessellation usage in games soon.

Hm, yes, I think Unigine looks better. I wonder if someone licensed their engine to create a game or two...
