iRay - The answer to VRay-RT from Mental

[Mikokariadis]

15 quadro's... I did not pick up on that while watching the video.

That is simply pathetic.

Hey, moment v-ray rt does open cl I buy it on the spot.

15 quadro's...pffft. No wonder they showed it where they did. Plus this quadro fetiche, it is looking as sad as that wildcat card fetiche mid to late 90's.

Cloud

I think people are missing the cloud point. You wouldn't need 15 GPU's; you would access a service using their 15 GPU's. I guess the cost of that service would be in question.

[devin]

Paying for a service just seems wrong plus I could foresee all kinds of technical problems that you'd never have to deal with if it were all on a local machine.

[Mikokariadis]

Cloud, grid, render farm. Let's just use something that doesn't involve someone charging me anything other then electrical consumption. That is my point. Clouds are for marketing people that like buzz words and another way to move jobs elsewhere for that matter.

A cloud based on very specific gpu hardware, how convenient.

I want Open CL and make it local please.

One thing that was pointed out on another board is the the iRay demo has 70 IES lights in the scene.

[panthon]

Wow i'm impressed. Regardless the number of gpus involved, there's A WAY to get that result in almost real time that wasn't available before. Now, evolve RT to that and I'll be happy
I see a future where RT window will be inside NUKE or FUSION and u'll be "comp-rendering" without thinking in "oldschool-rendering".

This is not directly reported to iray, but it's my old test for VRay-RT in a heavy scene.
6500 teapot (6.5 Million poly) (not instance, but simply copy geometry), all Glossy, 50 IES light with Areashadows + GI + DOF.
Plus a heavy geometry deformed in "realtime" with a modifier.
The slow part is to copy the 6500 teapot from 6 Million to 12 million ( 2 minute). But after that, VRay-RT works very well. .max file is 60 MB with 12M poly. Main PC is a dualXeon 5440 @3.250 Ghz 16GB + 2 node i7 @ 3.8 Ghz 12 GB.
I'm waiting the GPU version.

You can get the same performance from V-Ray RT right now through distributed rendering.

What I basically meant was that I'm waiting for GPU-accelerated Vray RT. I've been testing our RTs with plenty of computers in DR (7 or 8 dual quad cores) and feedback is not quite as good...especially in interior rendering (outdoor rendering, especially with VRAY Domelights, flies at full speed). Obviously we are talking about cpus and not gpus.

On the other hand, can anyone tell me what's that application they are using on the internet browser to control different rendering parameters, like time of the day and such? I can barely hear what the guy is saying. It looks like the ultimate client feedback application, though.

I thought one of the main problems was is it really cost effective to outfit a bunch of render slaves with GPU's? isn't that one of the reasons gelato failed.

It ain't, because you have to outfit said renderbox with a good CPU and a high-end video card, which is not cheap at all.

VRayRT GPU (as shown at Siggraphy) however, isn't pulling a "you need a quadro buddy".

[panthon]

I was thinking that instead of looking at a computer in the 3000-5000 euro range of prices, we should consider creating a computer+processing cluster in the 15.000 - 20.000 euro. That would allow client-assisted rendering sessions with acceptable lag. I was thinking about this as an analogy of Autodesk Flame and inferno, both solutions available in hardware-powered flavours, which cost (or costed) about 300.000 euros and 600.000 euro, respectively.

It sounds like a LOT of money, but specialized facilites were happy to pay it and crunch over 2K sequences effortlessly, mainly in the advertising postproduction field. Now if we think about the future of 3D interactive render, maybe we should start considering clustered DR nodes as a default configuration for any given "hero" workstation.

[dellis]

I'm not a hardware guy...and i already mentioned this....but does this mean that the machines that have multiple video cards...like mine which currently has two Nvidia cards in it with room for a third....would make for better machines to have as far as the real time stuff is concerned?

VERY different. Requires it's own shaders and workflow.

Hell.

No.
