It’s not up to me. UA-cam does what UA-cam does. I call the phenomenon “Recommendation Fairy”. Most of the time she slumbers, but sometimes my channel is blessed by her. Usually she directs the masses to my typing video. This is the first time ever that she directs them to a video that actually represents my channel well.
I guess it's because of nVidia's RTX graphics cards, UA-cam may have noticed that videos with "raytracing" in the title are currently 'hyped', so it starts recommending them.
Makes me miss the algorithm from 7+ years ago and how great it was at recommending quality videos. Lately it won't even suggest me the second part of multi part videos
Lol I actually watched the whole thing and when he typed in his information at the top saying made in 2011, I paused the video and checked the upload date. Then I was seriously blown away as an engineer.
It's only come to the mainstream attention and the masses as of recent because of that. Ray-tracing, given you were in the whole rendering 3-D images thing like myself, has been around for years and years before "RTX".
@@kilianbalter I think it's due to dithering. Dithering is an age-old graphics technique developed in the era where colour palettes were extremely limited. Basically it uses alternating pixel colours in order to simulate the existence of more colours than there actually are. For example, if you space out alternating black and white pixels and view them from a far enough distance they turn into grey. I think what's happening is that the 4K original loses so much detail as it downscales, that a lot of the dither is lost. You can see this when you change down resolutions. There's not a lot of difference between 4K and 720p, but you can see some of the colours getting blurred together or changed by the encoder. Once you drop under the resolution of the ray-trace renderer (480p), the colours start looking more and more solid thanks to the dithering being blurred.
It was mostly an effort to include hardware to speed up raytracing. Hardware is much harder to develop than software. It also takes up a chunk of silicon area without any speed up to other tasks. So increased cost for nothing for most users.

@@Bisqwit I had a grandma and she always complained about electrical bills and power consumption. She patrolled around house switching of any "unnecessary" appliances. That was the only reason why I kept my amigas locked in the closet. Now when I think back that was a tremendous fire hazard.

Testing. A few days ago UA-cam seems to have sabotaged retroactively all old comments, removing all newlines. Instead of a nice paragraph break between thoughts, there's now _nothing_; the next word starts immediately after a full stop without even a space. It is very annoying.

Funny, I was thinking near the end "wow, if I could take this back in time to the 386 SX16 and 486 SX25 PCs at school, everyone would freak the hell out" (they all ran standard VGA at the time) ...but then I realised "there's no way this animation would compress enough to fit on their hard drives using any scheme that would depack quickly enough..." and then "ah! there were at least a few with external CDROM drives..." Only to be further foiled by the final realisation that they were single speed drives, reading at 150kb/sec. And a high-rez VGA screen consumes... 150kb. Prebuffering isn't really an option, even via the HDD, as they all had 4mb RAM, no disc larger than about 170mb, and DMA disc transfer (instead of CPU-murdering PIO), even for the SCSI CD drives, was still a couple years in the future...

those 3d graphics are amazing.. i wish i know the mathematics behind the drawing......you even have reflection of lights. when i was using borland c++, all i could draw is circles, boxes, or .bmp pictures at best.
+imkow It is mathematics heavy, yes. For each pixel in the image, a vector is calculated representing the ray that is cast from the eye through that pixel in the image plane. Then a collision is calculated between the ray and each object in the scene. (Google-search: ray-sphere collision) If there are collisions, the nearest one is taken. The surface normal is calculated at the point of collision. The ray and the normal are used together to calculate the reflected ray, which is then recursively used for calculating reflections. Additionally, from the point of collision, a ray is cast into each light source. If the ray does not hit anything, then the surface point that was hit is lit by the light, and this is added to the result, multiplied by the cosine between the ray and the surface normal. This is a condensed explanation off the top of my head. More details in this source code and in other materials readily available online.
+Bisqwit Thank you Mister so so much ! that's very helpful. it's gonna take me days or months to digest those words...these knowledge alone are enough for opening a college in some university.. every part of procedures you just described is interesting and tricky enough(to be made into a series of tutorial videos, :D)...To mimic from this , I'm gonna try to realize a basic primitive reflection of lights on a graphics API called JavaFX, in a sample program just to test those freaking math......
This popped up in my recommendation feed not too long ago. How did I not find this video back when it was released?! This is stunning, gorgeous, and just... wow. You did a very very fine job!
Well,... nice but the educational part is reduced to code comments. If you ever wondered why people thought you were typing so fast (seen that in one of your vids): It's the clock in the top-right corner.
UA-cam: Ray Tracing is going to be popular in many games, even in Minecraft. Let's prior tag "Ray Tracing" in my platform. User: But this video is 7 years old. o_O UA-cam: I don't care...
I think that probably because the image quality becomes rougher, the dithering noise becomes invisible, which makes the image quality appear to be better.
Nice one, Captain Obvious. Though that's only really true for home hardware. If you were extremely patient then something analogous could have been brewed up on industrial machines. After all, that's how the planetary sequences in 2001 were produced...

Mixed with the midi soundtrack. I really feel something special. Such a great mix of old and new technology.
those 3d graphics are amazing.. i wish i know the mathematics behind the drawing......you even have reflection of lights. when i was using borland c++, all i could draw is circles, boxes, or .bmp pictures at best.
+imkow It is mathematics heavy, yes. For each pixel in the image, a vector is calculated representing the ray that is cast from the eye through that pixel in the image plane. Then a collision is calculated between the ray and each object in the scene. (Google-search: ray-sphere collision) If there are collisions, the nearest one is taken. The surface normal is calculated at the point of collision. The ray and the normal are used together to calculate the reflected ray, which is then recursively used for calculating reflections. Additionally, from the point of collision, a ray is cast into each light source. If the ray does not hit anything, then the surface point that was hit is lit by the light, and this is added to the result, multiplied by the cosine between the ray and the surface normal. This is a condensed explanation off the top of my head. More details in this source code and in other materials readily available online.
+Bisqwit Thank you Mister so so much ! that's very helpful. it's gonna take me days or months to digest those words...these knowledge alone are enough for opening a college in some university.. every part of procedures you just described is interesting and tricky enough(to be made into a series of tutorial videos, :D)...To mimic from this , I'm gonna try to realize a basic primitive reflection of lights on a graphics API called JavaFX, in a sample program just to test those freaking math......
Do you want to know how to do this?
Here you go! Thank me later! :-)

Well, I THOUGHT I was okay at writing in C. Guess I know nothing, now.
This was C++, but yeah.
*goes back in time to 1991 to chuck 16 3.5mm floppy disks with this on it at some programer's head*
Unbelievable - oh my god. That is amazing!
But you're mortal, HOWWWWWW???????
This popped up in my recommendation feed not too long ago.
How did I not find this video back when it was released?!
This is stunning, gorgeous, and just... wow. You did a very very fine job!
Back then I had like 188 subscribers. UA-cam does not promote channels that small unless their videos are already turning out very popular.
@@Bisqwit Ah. Either way, I was still shown something amazing, I just can't stop watching it now. It's a truly amazing piece of work you have done.
This is some pretty fucking rad stuff for !!!! I deeply admire you.
Funny that decreasing the quality to 144p makes the video look better in quality.
Alright then.
Holy shit you are right 😂
well its called antialiasing
That is anti aliasing tech.
@@kurostyx9124 It's called blurring.
Do you think I know what a JPEG is?
That is some incredible dithering, really beautiful. Smoother than most.
Well,... nice but the educational part is reduced to code comments. If you ever wondered why people thought you were typing so fast (seen that in one of your vids): It's the clock in the top-right corner.
movAX13h So, is he typing really fast or what? I'm still confused.
tool assisted video
This channel makes me happy to be experiencing life
The more I think about this video, the more things I'm impressed with. The code, the release date, the result. Insane! Amazing job!
You are the man.... Amazing!
This channel needs more subs!
This... This is amazing!!!
And also very, very trippy.
Heck, even the music sounds like it's from the 90s.
4:3 Aspect Ratio is perfect on my iPad!
I just can't get over that typing speed
Tales of Phantasia, such a beautiful masterpiece
UA-cam: Ray Tracing is going to be popular in many games, even in Minecraft. Let's prior tag "Ray Tracing" in my platform.
User: But this video is 7 years old. o_O
UA-cam: I don't care...
Lets hope youtube lasts a century or two, then its gonna get really fucking strange!
I know it, this is what's gonna make DOS popular again.
Also, wow, that raytracer looks _amazing!_
you are a genius
For the first time, something actually looks good in 144p, not 1440p, but 144p!
144P BOIIIZZZZZZZ
Wrong it's 144i 😂
I think that probably because the image quality becomes rougher, the dithering noise becomes invisible, which makes the image quality appear to be better.
This is amazing. Why is UA-cam recommending this in 2019?
I can see why you made this available in 4k etc. The compression really messes with the dithering effect at the lower resolutions...
NVIDIA Hates Him! Ordinary guy figures out how to get RT for FREE with this one weird trick!
:D :D :D
Not ordinary thats for sure.
Winston Deleon RT cores boost performance you can do ray tracing with gtx cards too...
bruh RT always existed
Raytracing existed for about 300 years.. rtrt however...
@@tootaashraf1 for more than 20 years. 350 MHz + 64KB were enough for real time raytrace, just three words: Seven Heaven demo.
I think what amazes me the most is how this is all done with only 16 colors and a shit ton of dithering
Graphics have never gotten better than this
40 years back this would have not been possible
+A23p Studios It would just very slowly.
+george allen It'd take the length of this video to render one frame lol
Yeah, K&R C is from '78 (if I recall correctly). 40 years ago would've been '76, and C++ was created as a superset of C.
Nice one, Captain Obvious.
Though that's only really true for home hardware. If you were extremely patient then something analogous could have been brewed up on industrial machines. After all, that's how the planetary sequences in 2001 were produced...
@@markpenrice6253 what do you mean planetary sequences in 2001? As in the movie by Stanley Kubrick?
My new go to video to see if my headphones are working properly
AMAZING, MAN!!!
Switch to 144p for higher quality scenery.
He does have a steady hand. This is just a lot more than outstanding.

As a college student working my way up my math classes I can't wait until I can apply all the math I've learned so far into programming
This popped up while I was looking up stuff on SNES Doom source code. Very unrelated, but I'm here for it! Great video

I love these videos because they are timeless. If I don't watch the uploaded date I'd just believe that it's a new video.
Nvidia : we launched a new feature in rtx called ray tracing!
Bisqwit : im about to end this man whole career
Well raytracing has existed for many many decades now. It's not a new concept. NVIDIA didn't create it.
I think we're forgetting the word "real-time"
