Most 3d shaders you see out there make use of this technique. Its the bigger brother of the more well know ray tracing technique. It's called ray marching and in this video I'll explain in detail how this technique works so you can start making cool 3d graphics yourself!

[@upalmucha6440]

--> receives free lesson --> shamelessly complaints about audio quality... Seriously? Thank you Martijn for this super useful video!

[@3FourFour5]

i think they fried their speakers, the audio quality is great

[@Hypnoticshark]

Looks like Christmas came early! This is the best explanation of ray marching I have come across. Thank you!!

[@JohnMarkIsaacMadison]

Swizzles make a lot more sense now that I see an actual use case for them.

[@michelangelowebb4362]

I agree !

[@dipaco_]

This is an amazing explanation of the marching rays. Awesome!

[@mcfoton]

Thank you so much for this series. You help me experience joy of all that ❤️

[@joshuabatty]

One of the best explanations i've ever come across, thank you so much!

[@dgoberna]

You made it again. Great entry explanation of raymarching. Concise, simple, easy to understand. Neat neat job, congratulations and thanks for your work.

[@Dezomm]

The way you explained it makes a lot of sense and I feel like I understand *how* everything works, so thank you for that! You're a great teacher!

[@somenicedutchguy638]

Awesome. How you explain the thought proces about the inner workings. The logic, just wow!

[@bruninhohenrri]

This channel fits like a glove. Thank you for the work !

[@JunkerJames]

Had been meaning to try this technique for years, but only just got around to it. This video was an amazingly good sanity check. Thank you so much for making it!

[@scorpion666lair]

This is exactly what I was looking for - please continue this path!

[@nuty7899]

Thank you for this amazing tutorial! I successfully implemented my first ray marching shader on my renderer. It looks awesome!

[@bbrws]

This is such an amazing explanation of the math behind raymarching - thanks so much! Everyone should sign up for the Patreon!

[@Udinanon]

I was watching a series of videos on Ray Marching lately and all skipped on many details and things, focusing only on cool effects and fractals, thankfully i found this video to help me understand all the basic elements Amazing work!

[@stromboli183]

Awesome explanation. You make some top quality content, good sir. Much appreciated!

[@PAEz...]

Awesome! This sorta stuff is a bit beyond me but I like knowing the general gist. This was so well made I really feel like I do know the gist now, thanks!

[@megaipks]

Absolutely amazing! Now I finally got the idea of raymarching! And it is suprisingly simpler than I think! Thanks mate! Keep your good work!

[@suvetar]

That's great stuff - thank you for sharing this, gotta say that I love your presentation style - you hit the nail on the head for my preferred style! Thanks again man; I am really looking forwards to checking out your other content!

[@arkondigital1496]

I'm impressed what Ray Marching can do! Feels magical

[@MichaelProstka]

Superb! Really dig the code being written as you go along.

[@taylor.matson]

Excellent video covering a lot of the basics! Should be the first video in any Raymarching playlist ;)

[@NullM0niker]

Very helpful! Thanks for taking the time to make this.

[@jeyko666]

[@helo3153]

This chapter is really super useful, thank you again!

[@realcygnus]

WAY cool my man ! I find this extremely interesting, exactly what I was hoping you'd eventually cover. Long time no see. It seems I wasn't getting alerted, damn ty notifications. I got a few vids to catch up on anyways. Thanks for sharing, you're so awesome at explaining these things.

[@futureartist6420]

Your teaching method is the best. Thank you very much

[@sacredbanana]

I've been waiting for this video for years! You cannot comprehend how happy I was to see this in my subscription feed today! Haha thanks so much!

[@TheArtofCodeIsCool]

Awww.. you are welcome!

[@RussPainter8]

Great explanation. Your graphics really helped get the point across.

[@kovnokl5941]

damn you're crazy... explained such a complex topic, that even I could understand everything you said with only one time viewing the video... Big props

[@ilmaros]

I really like that you continue to make these very helpful videos ... Thank You :)

[@JoeNo310]

Thank you for the clear explanation of an otherwise complicated topic!

[@granolakitti8521]

OMG this is magical. Thank you for making this

[@nickfaro5764]

Awesome vid. Never really knew how raymarching worked

[@kimnielsen7818]

Just found this tutorial and even though I'm not doing it in a shader (I wanted to make it in python) I find this very useful so a big thank you!

[@JosephAzarlyon69]

Thank you ! your skecth/diagram helped me a lot. Great explanations

[@bensteer2389]

Really interesting and well-made video, thanks a lot!

[@CaduSaMotta]

Congratulations! Great work.

[@binhql]

Thank you so much. Your teaching skills are wonderful!

[@sagielevy]

This really is for dummies. Thanks for the amazingly clear explanation! Would love to see more stuff coming out :)

[@TheArtofCodeIsCool]

Hehe, yeah I try to explain it as basic as possible. Glad you like it and thanks for watching!

[@andreidoanca4262]

thanks for this cool tutorial. really well done

[@TerminalStage]

Great work! I tried to understand it by myself, looking at examples on Shadertoy, but I failed :D Your explanation is so easy to understand! Thanks!

[@jobemattcurr]

Thank you! This is one of the best tutorials for anything I have seen in my life. Simple enough to grasp as a beginner, yet it's simple without glossing anything over so you really get to understand everything you learn here. An excellent starting point for anyone interested in ray marching!

[@TheArtofCodeIsCool]

Thanks! And thanks for watching!

[@krisp-]

I replicated this in Blender with the node editor. It is probably the most impractical thing I've made, but it was fun. Thanks for the great explanation/tutorial!

[@mr.hashundredsofprivatepla3711]

How did you deal with the raymarching for loop in the node editor?

[@hvanmegen]

that keyboard rumble caused my glass to be bounced from the table by the thundering keystrokes coming from my sub

[@5589e5]

Thank you for making great stuff!

[@StriderSeiryuu]

wow! really nice explanation, Thank you!!

[@Tony-tu8uz]

thank you for a very consistent explanation :)

[@Finofinissimo]

Powerful stuff. Thanks for sharing.

[@fonzjedelarosa7587]

Excellent tutorial Martijn, bedankt!

[@meowyih1]

After read dozens of articles and videos, I finally found one that I can understand. Thanks a ton! m(_ _)m

[@Michallote]

The fact that you can create something like this out of small samples of code and some very neat core ideas, makes me believe that it could actually be possible to simulate a world so realistic people don't notice right away they are in one

[@TheArtofCodeIsCool]

That is where we are headed, absolutely.

[@consumer2014]

holy shit the sub bass in this is wild!! lol anyway, thank you so much for this amazing walkthrough. extremely clear and organized. thank you!!!!

[@browneric2458]

This is really really helpful, thanks a lot!

[@achimstromberger]

very well explained, thank you!

[@PeterParnes]

Great introduction. Thanks!

[@alihelmy]

Very nice and clear explanation. Cheers

[@jaroslawmichalski9021]

It is a really good video and great explanation. Thanks a lot.

[@kamiltrzaska]

Thanks for the video, it seems so simple now

[@AtmosMr]

Thank you! Very well explained video. Great pace for a newbie to ray marching. Thumbs up!

[@AtmosMr]

Ooooo, thanks! btw - you can't hear you at the end as the music drowns you out. But great - I'm fired up!

[@BruceLane]

very helpful, thank you! btw the keyboard shortcut to run the shader is alt-enter

[@tkasch2505]

Absolute great, thank you!

[@nemesiswes426]

Awesome video, super easy to understand.

Awesome tutorial, so easy explained, that even a 9th grader (me) can understand it! Thank you so much!

[@TheArtofCodeIsCool]

Awesome!

[@hanniffydinn6019]

Distance functions are where it’s really fascinating! For interesting objects the distance functions are fun.

[@TheArtofCodeIsCool]

Yep :)

[@LinusDev]

Thanks for the great video!

[@coolfunmario]

thank you so much !!!!

[@ishdx9374]

really well explained!

[@ArminJohansson]

I'm gonna learn so much from you it's carzy

[@DylanBurke]

I'm addicted to your videos. Your newer ones don't have this issue, but the keyboard thumps that get picked up by the mic here are really distracting. Seems you've been more mindful of that since then though. Thank you so much for uploading this stuff; will support when I can!

[@TheArtofCodeIsCool]

Thanks for the feedback. I'm trying a lapel mike next, hopefully it will get better!

[@ralofpatel470]

Subscribed without wasting a second

[@josephruiz831]

I love your videos, truly. Excellent explanations! I do feel like they would be easier to follow with actual variable names. I realize most shadertoy authors go for a more codegolf approach, but it'd be nice. Keep it up!

[@TheArtofCodeIsCool]

I feel you and I will try to be a bit more descriptive in certain cases. Having said that, a lot of the short vars are almost convention; everyone uses the same names. This way, you can get used to the names which makes it easier reading other peoples shaders. Also, it makes it faster for me to type (my vids are long enough as it is), and easier to use in formulas.

[@Heisenberg2097]

Great video!!!

[@UnitCodesChannel]

Well explained. Super Cool!

[@anotherplatypus]

Yeaayaa, omg I'm so glad you exist! Not knowing how to program shaders is a very subtle restriction like.... sheeesh describing how it feels to be limited by it is tough... Ok, it's like loving to work on cars, but you can't touch the electrical systems. You can master whatever as long as wired parts remain a mystery. The longer you do it, the more apparent it becomes that simple fixes can become ugly kludges, large-scale improvements rarely feel perfect, and when you're done... there are haunting moments when you just gotta hope the lights come on, the car will start, and it won't die in front of anyone later on.

[@TheArtofCodeIsCool]

Haha, that could be the foreword to the shader coding book I'll write one day ;)

[@anotherplatypus]

@@TheArtofCodeIsCool Wow..., that is without a doubt the nicest thing anyone has ever said about one of my comments.... thank you. = )

[@atagen2186]

have you tried tbos? thebookofshaders.com it's mostly generative focused but you can apply a lot of the same techniques to image sampling too

[@Haykke]

*Starts explaining..* me - *instant like*

[@JocelynDaPrato]

Nice video. I'll try for sure :)

[@ornellaocchipinti2177]

Brilliant! Thanks
