[@chosenideahandle]

Was that lecture interesting to me? I used to teach this stuff at a college over ten years ago, and I was glued to the screen Andrey! Your clarity and animation of the concepts, comes together to make this a real gem for people struggling with this stuff. So well done. If I still had CG students, I'd have them all subscribed to your channel!

[@AndreyLebrov]

Thanks mate. Your my top supporter 😄 appreciate your comment 👊🏻🙏🏼

yes i think he has a talent for clarity, a student would be lucky to have a teacher this good.

I was thinking why there is no one explaining this and then I came to your video. Give this man a medal, best video I watched on 3D light explaination.

[@kaitsurugi3280]

This is the most simple yet comprehensive explanation of this topic that I've seen yet! In fact, this is one of the best explanations about anything that I've seen. It's Amazing! You're Amazing! The visualization of the concepts being explained were a very big help, thank you for taking the time to explain this topic to us!

[@alvarezjuliom]

I have watched dozens of videos explaining those concepts. This is the first time EVER that a single video explains Ray Tracing and Rendering Methods in a simple and clear way. Looking forward for the next one Andrey!

[@HaVoCX64]

That vizualisation is absolute genius. There is no better way of showing the rasterization process to people than this animation. I'm a graphics engineer and I guarantee every word in there is truenews. Absolutely correct. Witted is mentioned as the cornerstone person to revolutionize ray tracing in 1980; I shall complete the information by saying that the path-tracing method is by James Kajiya, in 1986. peace.

[@LeagueofEditing]

You are easily in the top 3 of my all time inspirations on youtube. I can see your passion in every bit of your videos which motivates me so much to push my limits as a self taught video producer. Thank you!

[@Alexandra-Rex]

I knew only the very basics when a friend asked "Ray tracing?" when me and someone else talked about the 2080/2080 Ti performance and prices, so I found this and gave him. Such a great video to explain and shot how it works! Great work!

[@hoimarsimpson9859]

Perfect, Andrey - you're an exceptionally gifted teacher, too.

Hi, i was making a video on ray tracing implementation in commercial games. Looking for reference animation and images, I stumbled here. Unbelievable man, those animations and the way you explained, TOP NOTCH!!!. I would be happy to use some of them over my commentary, if its okay with you and ofcourse with credit. The best explained, i have gone through almost all of them around.

probably a combination of masking and the Displace effect in AE

[@AndreyLebrov]

Vray initially was a Ray-tracer. Nowadays it offers both Ray-tracing and path-tracing methods.

[@debajoytikarmakar8601]

okk.thank u.

[@GuilhermeMaia100]

​@@AndreyLebrov Can V-Ray use only Ray Tracing? From you explanation what I understood is that Brute Force is the path tracing of V-Ray and others GI methods are non path tracing. Is it right? Awesome video. And did know about ray casting and didn't know that was a predecessor of ray tracing.

[@于泓-v2i]

Best explaining video I have ever seen. I have been confusued about so-called the terms like ray tracing and path tracing and want to know the exactly relations between the principles and the actual visual effects shown in render engines. You clearly explain them and even present it by using 3d samples. This is amazing. Thanks Andrey, now I become your big fan!

[@nathangamble125]

Historically, raycasting didn't use an array of millions of rays, it only used one for each horizontal pixel, and textures were stored as vertical lines, which were stretched depending on their distance from the "camera". In DOOM, there was also a height map which determined how high up the screen the textures would be drawn. This is why you cannot look up or down in DOOM or Wolfenstein 3D, but it allowed early 3D games to be made and was much easier than early rasterisation techniques.

[@omf-arch1765]

The greatest the most valuable video ever that explains in the most simple style and language, the best demonstration of anything I've ever heard in the whole industry, Andrey, KZbin без тебя - ничто !

[@srjnm]

Can you explain UV Mapping please? I am guessing most of us are really confused by the process involved.

[@AndreyLebrov]

Okay :) at some point I will

[@srjnm]

[@philippesteindl3356]

From what I know, a UV map is the exact same polygons you have in your mesh .. but in a 2D flat arrangement (hence U and V coordinates opposed to X, Y and Z). Of course this will always stretch/contort your polygons, since you can not properly display a 3D mesh flattened down to 2D (like topographic maps of the world). The trick is to select a projection method that works for you (from the top, "smart" etc). You can also manage it manually to move whatever vertices to your liking. You can usually also tell the 3D program to break up the 3D mesh at specific "seams" so you can more smartly get the 3D mesh into a 2d display (imagine cutting up a 3D model of a microphone with scissors, cutting off the cylinder below, then cutting up the sphere above along a proper line etc ... this helps the UV automatism to create nicely arranged 2D meshes of your 3D mesh. And finally, a 3D program will allow you to manage the texture of your material across the UV map, so you can decide where you put what image detail onto your mesh. In short: Imagine meshed kitchen sieve, your 3D mesh. Smash it with your fist into a flat thing without any overlaps, that's your UV map :)

[@johnroberts8088]

UV Mapping and the unwrapping process. The basics of what UV mapping I don't find that hard, but when I come to unwrapping and manipulating, I get totally lost.

[@denethv8530]

Andre Yurenkov I think It's Ae and Can be easily done with MotionBro transition packs

[@PeterJansen]

Wow you went quite in depth. My biggest eureka moment as a VFX artist trying to understand rendering was discovering all the many types of distributed effects there are. Instead of you camera being a single point in space, you randomly distribute the rays you cast across the area of the lens, thus bokeh. Or distribute them across time for motion blur, or around the reflection or refraction angle for roughness, or all around in a hemisphere above the shading point for indirect lighting (global illumination). Or of course, across the area of a light for soft shadows like you mentioned. I fuckin love modern renderers.

[@Mac_Daffy]

That is quite in depth as well. I did not understand all of the distribution concepts you explained but would love to. Any sources you can recommend?

[@PeterJansen]

Well, this one is super duper in depth: kzbin.info/www/bejne/op_VfoqMn916g68. At 16:30 he talks about depth of field and then motion blur. This paper is also good: graphics.stanford.edu/~boulos/papers/cook_tr.pdf

[@Mac_Daffy]

I just had my own eureka moment. Thanks for sharing! Before the original paper I used those lecture slides to get an overview: cglab.gist.ac.kr/courses/2018_spring_cg/2018_05_21_Distributed_Ray_Tracing.pdf
