While I'd love that, I don't think that's the case.<br /><br />Judging by the video you posted, in that video it takes about 2 seconds for the image to converge and be noise free. Which means 0.5FPS for noise free image.<br /><br />Given the fact that we need around 50FPS for playable games, that makes the factor 100x of the current level.<br /><br />Also if we factor in the fact that like you said you are using two Titans, well then the factor goes up to 200x the current level of a single top end GPU.<br /><br />So, I'd say that 5-10 years is more like a realistic timeframe, providing we will also have algorithmic improvements.<br />mirrormirrornoreply@blogger.comtag:blogger.com,1999:blog-7277449027963623452.post-27227644988076486902013-11-20T11:02:19.861-08:002013-11-20T11:02:19.861-08:00If anyone has trouble downloading from MEGA on fir...If anyone has trouble downloading from MEGA on firefox, get the MEGA extension add-on: https://mega.co.nz/#firefoxAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-7277449027963623452.post-53949184627905819102013-11-20T10:49:40.649-08:002013-11-20T10:49:40.649-08:00Has anyone been able to download the Brigade video...Has anyone been able to download the Brigade video from MEGA?

You probably heard of this new true audio (or something like that can't quite remember the name). Lots of people have mistakenly thought this was a sound card replacement, IT@S NOT. The new cards now include a VERY powerfull programable DSP on die, the dsp is being used for this new level of sound processing but after looking into it further being a fully programable DSP it can be used for anything the user likes if you write your own code. Im looking at ways this can be used for even faster BVH builds etc etc, Thinking even a realtime low latency noise reduction algorithm is more than feasable. You and your boys should look into this. Let me know what you think Bruda.

Regarding multiple lights, Brigade 3 has a specific optimization to deal efficiently with hundreds of lights of varying size and orientation. The next demo will have something to do with the Lamborghini model.

If you haven't checked them out, you should. They're some of the most realistic real-time 3d models I've ever seen. There's a downloadable demo called HydraDeck-Humans that you can check out if you've got an Oculus Rift. Inside the Rift they're so realistic that it's almost creepy that they're not moving. It feels like they're real dead people. I think Brigade combined with those models, realisticly animated, would be the holy grail of gaming. Here's a quick video of the demo.<br /><br />https://www.youtube.com/watch?v=7bytIGCeGxoAnonymoushttps://www.blogger.com/profile/12754648455985129572noreply@blogger.comtag:blogger.com,1999:blog-7277449027963623452.post-23158507744957116542013-11-05T02:33:52.818-08:002013-11-05T02:33:52.818-08:00Thanks Sam for screens and vids, but i'm sure,...Thanks Sam for screens and vids, but i'm sure, obviously, this scene can't show even 10% of brigade potential.

It's often more advantageous too spend more time on rendering extra samples instead of filtering pixels with not enough samples. And even though the amount of noise (variance) gets cut in half with the square of the number of samples, the perceptual difference in noise between 4 and 16 spp is much larger than the perceptual difference between 16 and 64 spp.<br /><br />colocolo, Anthony: I'm not too worried about hitting a wall in the performance increase of 3d chips, but I do believe that some of the stages in the ray tracing pipeline can be massively accelerated by dedcated hardware. Now is the perfect time for Nvidia and AMD to look into that, because the next gen consoles will stagnate the advancements in game graphics for another 5-6 years until the cloud takes over completely (I'm fairly sure there will be never be a PS5 or Xbox One.5) <br /><br /><br />Sam Laperehttps://www.blogger.com/profile/05688552048697970050noreply@blogger.comtag:blogger.com,1999:blog-7277449027963623452.post-8480849083126317022013-11-04T12:54:57.924-08:002013-11-04T12:54:57.924-08:00Mr Papillon: thanks, fixed now :)

The scientific and engineering communities depend on it, and that's the prime reason a lot of supercomputers even exist. That's an unfathomably big industry. Everyone from professors and grad students working with theoretical models, to big agencies like NASA and pharmaceuticals need to run compute-heavy models. Then you've got agencies that just deal with a lot of computation in general, like the NSA and private firms. <br /><br />High-performance computing is in higher demand now then ever. We're not gonna see progress suddenly stop, because too much of the world depends on it progressing as quickly as it can.

Intel at least has been working with theoretical models to shrink all the way down to single-digit nanometer feature size using modifications of current tech. And there are also entirely new ways to do it that are in R&D phase; entire departures from photo-lithography. <br /><br />We also have 3D chips to look forward to. Successful implementation will be more significant than the boost Moore's Law gives us. We could be scaling much more than just 2x every 18 months. <br /><br />It's a problem worth thinking about, because the problem IS real, but that doesn't mean solutions don't or won't exist. Computers are not hitting a brick wall. We have many more performance increases to look forward to for the foreseeable future.

RE: prerendered animation, Brigade isn't really made for offline rendering, it would be easy to add such functionality but it would defeat the purpose of real-time path tracing. To give you an idea of the quality we can have with Brigade with instantly noisefree images, check out this CG animation: <br /><br />https://vimeo.com/37517970 <br /><br />Right now, Brigade can do the exact same thing as what you see in the animation sans the smoke and motion blur. That animation actually inspired me to try the NYC scene you see in this post (and which was featured in my first blogpost in 2008) in Brigade and I must say that the results greatly exceeded my expectations.
