I got the other problem, the lights are on but nobody is home

Your monitor?

Yes and no. If u for example walk on grass the grass moves with u same for high winds or for example if u swim or u jump to water u see the psychics of moving water. I don't think the problem is the psychics is. More likely the graphic is almost on the limit now is only one step over that and this is real life footage graphic that the graphic looks so realistic that u can't see a difference between for example rocks in game and rocks in real world...

Depends on the engine the game uses

@Tyler Russell what differentiates between whether it uses the RT cores or the regular processing? I mean theoretically you could configure it to use those cores right or is that something that only Nvidia does? cuz that would be an annoying licensing issue in general

Cycles*

Cycles isn't raytracing. Classic Blender internal is raytracing. Cycles it pathtracing. The difference is that rays bounce in path tracing, they just end when you hit something in raytracing

I would say path tracing is also a form of raytracing. It's just a far more sophisticated, realistic and expensive form of ray tracing than for example primitive whitted style raytracing. The main difference is that in pathtracing we trace a much higher number of rays.

Correct, path tracing counts under ray tracing.

One of the first papers (if not the first) about ray tracing has formulas for it: citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.156.1534 . But there might be improved formulas or already existing libraries/frameworks out there.

im sitting in a room with light. but that light comes from behind my slightly open door, not giving me a visible light source to use

@@pr9101 That just means you have to switch to path tracing.

give it a few years..

I really hope so!

In few years, people wont even remember they complained about ray tracing.

Its not what you wanted but it IS what you need.

it does help production IMO, at least for individuals. I mean, with RTX integration into many raytracing render engines, you see quite a decent speedup, which is great, especially for previewing a scene (for finals, you might have a renderfarm anyway).

Nvidia didnt invented ray tracing, but they make it real time instead.

All hail CUDA.

But I think part of the criticism is that the video card market is suffocating, and the demand for affordable, significant upgrades has been met with immature technology that's costly in every way and might not be important until their next upgrade.

The memes aren't making fun of the general technique of ray-tracing. They're making fun of RTX.

There is more to rendering games than just throwing more cores at the problem. Its only logical someone HAD to move the technology forward, just as programmable shaders replaced fixed-function shaders, raytracing will slowly replace programmable shaders. Clinging on to a limited technology is never a good thing, even if it upsets people in the short term due to the cost it will improve game visuals and make developeing those games a bit easier in the long term.

Because you HAVE to buy the top-end model, right?

Ey

Was thinking this exact thing when I got to that part of the video, legit had to pause and have a "hang on, what did he say?" moment. Also, fun fact, Turing also accelerates the actual process of tracing individual rays, as the RT cores accelerate structure traversal and intersection tests. That, combined with the AI denoiser cleaning up the image, is what allows Turing to do "real time" raytracing.

Description of rasterization was all kinds of funky as well.. Most nvidia demos used standard bilateral filtering and so on, will be very interesting to see what techniques we will see in future.

@ThaKos69 it should be (( Real Time x Ray Tracing) x 1040) + ti = (RT x 2 x 1040) + ti = RT x 2080 +ti = RTX 2080ti Smh😒

R = 18th letter T = 20th letter X = 24th letter 20+24-18 = 26 26÷2=13 Illuminati Confirmed

not only that but its actually less work to develop for a ray tracing API and for the most part rasterized work will only be improved by ray tracing techniques with zero input from the developer (unless they want to aim for photorealism ofc), I can see engines like unreal and unity working in both raytracing and rasterization really soon.

I call BS, how would you watch the video? :p

I am sitting here in bright sunlight "puts on shades"

You're the funniest thing I've ever seen

I'll watch it if it's shorter than 15 minutes

Isn't that "noise" caused by the sparsity of rays used to cut the ray tracing to a more manageable task (something that a GPU can handle in a fraction of a second instead of days) rather than any consequence of Ray Tracing itself? And nvidia's fancy pants technique is to blur and approximate the missing data.

raytracing in its simplest form doesnt introduce any noise as youre only tracing as if all surfaces either dont reflect light in any direction but towards the camera or are only perfectly reflective. as you can imagine though in the real world light scatters off of surfaces in all directions (usually). so ray tracing in the simple form isnt noisy and also isnt super taxing, but that also wont give you: soft shadows, global illumination, things like caustics, etc. which nvidias stuff definitely allows for. to get things like, for this example soft shadows, in real life soft shadows are caused by the fact that there's no such thing as a point source light (infinitely small point light), all lights have volume. so in order to get soft shadows with ray tracing, when you sample shadow rays you need to sample randomly within the volume of the light source. and the keen among you may realize that once you start randomizing the direction of things whambamshapow, youve introduced noise into the picture (literally and figuratively). the same goes for things like global illumination where you need to take into account radiance of objects and smartly do multiple bounces off the initial object to simulate how light bounces around a scene and light from a green wall may reflect off and and onto other objects. theres randomness there that introduces noise as well. usually the way to deal with this kind of noise is just to render the same thing over and over and do a rolling average to converge the frames into a progressively less noisy image. but thats why this is hard to do in real time, you cant sample enough randomized paths to converge enough to the ground truth to look good in real time. at least, not without a good denoiser. and nvidias denoiser is really good, way more than just bluring/approximating. if its anything like the paper i read on a similar denoising technique, it uses machine learning combined with a rasterized render of the scene and some other wizardry to reconstruct the image. you can easily find examples of it being demonstrated with the denoiser on and off, basically can turn an unrecognizable noisy mess into a clean crisp image, with the occasional artifacting of course. hopefully this clears it up a little, so in one way yeah ya could say the noise is caused by making the task more managable, but i do think it is a fundamental issue with ray/path tracing. tho the more i think about it i guess if ya just had an insanely powerful computer that could crunch enough paths in realtime it wouldnt be an issue. its hard to word how i really feel about it but the noise is a fundamental property of light really. you get noise in the real world for similar reasons, like low photon count. things can look noisy just in your normal vision at night. and especially with cameras. just the fundamental way of basically accumulating photons looks noisy when you dont have enough photons. and same when you cant trace enough paths in ray tracing. so, eh, i guess ¯\_(ツ)_/¯

@@Bolt6265 this channel is called "techquickie". Of course they'll gloss over fundamentals. Make your own video. I'm serious I'll watch it. Just don't make it a half-hour long thesis.

Bolt Man Whoa there, we've got a know it all. lol kidding around but remember this is 'Techquickie' not Tech-hour-to-explain-every-single-detail-fully, dont get me wrong I would watch a longer vid with more detail but this channel is for quickies (I think around 7 mins or less fit that bill)

Facts

"become" is the word. There is nothing for the normal gamer to use it for.

indeed even with better drivers and software to work with i dont think youll be seeing much in the well mainly tripple A games that have ray tracing built in and youll be lucky to see a 60fps at 1080p with a 2080ti or 2080. It requires a lot of power to render per second and the fact they nvidia and amd have been able to do so in real time at 30-60 frames per second that is god damn impressive.

See as how a lot of PC Master Races are allergic to sub 120 fps images, probably won't see much sheeple celebration for it in a while as well.

It's exciting tech but give it time. Not currently practical if you prioritise fps over visuals (like competitive gamers)

Why is nobody considering that using RTX actually reduces the load on the shaders? If developers allow people to choose the RTX complexity in the scene you could easily have a gorgeous 60fps game while still allowing much higher frame rates at the cost of it not looking as good, but likely STILL better than shaders alone.

'minutes or even hours' lol... I would be glad for that! Depending on the scene, minutes for a complete and somewhat noise free frame is pretty damn amazing.

No, we didn't use ray tracing before this in 3D games, before baked lights we just didn't have lighting

@@alexbaker1569 im just saying that we had baked lights for a long time.

@@IAMDIMITRI true, but that's not what you were saying, you said we have used ray tracing in games before, which is false

@@alexbaker1569 That's what you do in for example counter strike 1.6 when you create maps. Light gets ray traced and baked onto textures. I'm certain that the whole quake engine uses this method.

@@IAMDIMITRI yes, we used ray tracing to create maps, but once the maps were created it was baked in, we have never before used real time ray tracing, the kind that is now starting to used in games

2 years behind

a renderfarm is usually used for animation rendering tho, to keep rendertimes below centuries, so I wouldn't really call it 'real time'. But I mean, real time is pretty vague. If you have a good PC, you can often preview your scene somewhat interactively (if it doesn't contain really computationally expensive things like detailed volumes etc).
