Hi everyone :) Not sure if this was clear from the first video, so to preempt any possible confusion about how this episode connects to the hydraulic erosion one -- it doesn't! The plan for this series is just to explore a variety of topics as I discover/become interested in them. So while I'll definitely be returning to the erosion project, there'll probably be a bunch of random stuff before then. With that said, I hope you enjoy the video! And as always, links to my project files, as well as the resources I used to learn about this stuff are all in the description.
I'd be intrested to see more about the erosion project. Might be interesting if it worked toghetter with the Procedural landmass generation in some way.
Ray marching is super interesting! As is this series. I've learned a lot from you over the years, so thank you mate. I also had a ton of fun working on a fork of the Path Creator project 2 months ago, check it out if you have some time :)
What you are doing with this series is fantastic, intuitive, and very entertaining. I love the improvisational nature of it where any given episode isn't related necessarily to the last. With each release, I find myself enthralled in your new project and in admiration of your curiosity. Keep up the incredible work! And thank you!
Sebastian Lague has to be my favorite coding youtuber. Its just the fact that all of his coding adventures are so interesting, entertaining, and most importantly inspiring.
Seb I watched the entire video with my jaw dropped because I have no idea what the hell you're doing. You've truly transcended into Ultra Instinct. Proud of you man 😭 also, request: can you visualize 3D ray marching like you did 2d?
Hey don't feel too bad, while I get a lot of these "free" calculations and renders are the result of caching the results of the technique and then coding stuff with those cached results, I can't visualise the actual code using those cached results in my own head.
By far the most easily understood Ray Marching video I've seen! I love the was you showcase code examples in a non-intrusive way, but still enough to get a basic understanding,
I was looking for this comment! I know the visual person or whoever made a lot of the shapes very mathematical. Like the flowers and the mold were fractals. So I bet it was planned and the alien was that shape!
I watched this video 3 month before and had no idea what you talking about. But during the time I started to learn some basics about shader and ray marching, now by rewatching it, I found myself able to understand it and even comprehend some math logics you've used for certain effects.
Woah, Sebastian! 8D Most of the images in this video were incredibly satisfying! Thank you so much for diving into these adventures, and for sharing them with us
I don’t understand how you can make a video that cool looking, yet at the same time super informative... And it’s just 5 minutes! That is really impressivez Thank you.
I'm still relatively new to programming and these coding adventures are refreshingly creative. I'm loving every second of these. Can't wait for the next one.
I've only recently started in unity and learning coding. It's wild how only a short time ago I didn't understand most of anything you were talking about for code, or what I was seeing, but I thought things were interesting. Now I get little inklings of clues as to what is going on. I can't wait to keep on learning, and then eventually mess around with code in the same way you do!
Dude I love these videos. Any tips for someone to get started with such topics? I have extensive "standard" software engineering knowledge, but really no idea about graphics and all the other cool stuff you do.
Wow, this was really phenomenal! I like this format because you can experiment without being forced to slow down for long explanations and tutorials. That being said, I'd be thrilled if some of these videos turn into a tutorial series!
Expected the video to be trendy clickbait, learned about ray marching, clicked subscribe. As other comments have said, really nice format! No over-complication, just clear explanations backed by simple and easy to understand examples. Nicely done!
You're an inspiring person my man, I'm not on this level of coding but the things you do just captivate me. Love to see more of these videos maybe even longer videos either way I'm here and entertained
NO! If a recruitment agent gets him, no more this kind of videos. Company secret. Fuck Marvel and CGI studios!!! For someone is a lifetime opportunity and for others is slavery to trade secrets and other corporative BS. A similar thing happened to some YT channels.
it probably isn't too hard just to do a really basic opengl renderer and throw in imgui, with some inputs hooked to shader constants--then again raymarching is all in the fragment/pixel shader (whether you're an opengl or d3d guy!!) If you wanna get started on raymarching you can use shadertoy.com -- it sets up all the opengl stuff behind the scenes and lets you just write fragment shaders
Amazing Sebastian! I'm glad I stumbled across your videos! You have sparked creativeness in my brain! I hope to show you something you have inspired some day!
maaaan you are one of the best mentor n thinker ive seen on youtube !! thanks aloot man these stuff are really wholesome !! i got a question wich version of unity do u work with ??
Just what I was looking for! Currently prototyping a game that deals with clay and needed to figure out how to blend geometry seamlessly. This will be helpful.
Love the series! It is introducing me to so many topics that I didn't know about but find super interesting. Your serious has inspired me to try out some of my own ideas with ray tracing. I'm eagerly awaiting your next video!! 😁
Man, I don't usually comment on youtube for quite obvious reasons, but your channel is amazing. As a serious competitive programmer for four years and discrete algorithmics student, I can say that your videos are a truly incredible blend of theory and actual codings. A lot of kudos
this stuff is extremely interesting. thank you for showing us all the experimentation results! i hope that once i have more time in my life i'll be able to mess around like this too
This is so cool this stuff very mesmerizing, really enjoying these videos ignites my passion for coding. Which I need for uni at the moment cause of the coding we are doing
If you know the ellipsoid method for solving linear systems, it provides a nice way of reducing the number of iterations on near-misses / almost parallel hits of flat surfaces (i.e. only works with boxes). If you don't know it, it (linearly) transforms flat shapes so that the closest one always stays at the same distance, while preserving volumes. This is the sames as squishing the distance sphere near flat surfaces to a pancake, so that you can move farther parallel to the surface in a single step.
Woooooah. That 3d fractal had me mesmerised indeed. That's a direct sub my dude, amazing content, great format, nice presentation. Keep it up, you're good!
I love your videos! Been on a few coding adventures myself and I'm considering posting a video or two. Not sure whether to feel spurred on or completely outclassed! 😊
Ray marching is cool, I particularly like Ray marching based and casting hybrids for voxels, which marches one distance each step, then tests intersection of the eight surrounding cubes, making a relatively speedy Ray casting engine for rendering voxels.
I was never great at maths. But maths and design intersect on a level that makes me marvel. To me, a religious person, it feels like the design of the universe is so mathematic. Watching these is like watching a sermon xD. But better tbh. Gorgeous work.
Hi. I really like your video, I love that you take initiative to create cool things via coding. I see you like creating images that are aesthetically pleasing and tries to model nature, much like I do. Currently I'm looking into galaxy generation. The idea of how the colors would look and how the galaxy form intrigues me. If you're looking for a new project some day, I'd be delighted to see how you would take on one like this. Keep up the good work!
Rendering an object as only the intersection of two metaobjects (or whatever they'd be called) seems like a really good way to do crazy stuff with the 4th dimension

That pythagoras animation had me in tears
I actually LOL'd, which I rarely do
Pythagoras, the master programmer.
same lol
me too 😂 didn't see that coming
Slap slap
Your visuals are so nice looking! I'm interested to see what else you do with ray marching :)
Thanks, means a lot coming from you! I’ve had so many people recommending your videos in the comments, and I can see why - your work is incredible.
Hello cp! Btw your non euclidean engine could of been done in quake live since that game has seamless portals.
It would look so good in marble marcher👀
hello code parade i was just thinking of you for some reason lol
Aren't you the guy who made an entire game out of ray-marching fractals?
I really like this format of videos. As usual awesome
Thanks, happy you like it! :)
those 2d visualizations showing how the algorithms work are awesome. (the rest of the video too)
Sebastian Lague has to be my favorite coding youtuber. Its just the fact that all of his coding adventures are so interesting, entertaining, and most importantly inspiring.
Seb I watched the entire video with my jaw dropped because I have no idea what the hell you're doing. You've truly transcended into Ultra Instinct. Proud of you man 😭
also, request: can you visualize 3D ray marching like you did 2d?
Hello jabrils
Thanks :D
Had a quick go at your request. It's a little ugly, but take a look here ruclips.net/video/0J8tKGjEE5Q/видео.html
@@SebastianLague wow that's awesome
Love to see you here Jab!
Hey don't feel too bad, while I get a lot of these "free" calculations and renders are the result of caching the results of the technique and then coding stuff with those cached results, I can't visualise the actual code using those cached results in my own head.
4:30
"Dormammu, I've come to bargain!"
Exactly what it reminded me off
I wonder just how many particle and smoke effects in VFX for movies are based off fractals.
@@ccricers I wonder are they writing codes when making CGI.
Lol
HA
I don't understand anything in this video
But still enjoy it
Pretty shapes and colors!
Same
This format made me activate the bell. Keep up the good work!
Some technique like this one was used on the movie “Annihilation” for the alien life form, pretty spectacular
It feels so good to hear you say "I have no idea how the code works, but..." :D
Your videos are amazing-the visualisations are so clear and easy to understand!
Thank you for sharing this with us, it's very helpful and inspiring.
You are amazing teacher. I love how you focus on foundational functions to express conditional intersections and blends!
Absolutely mind boggling! This kinda reminded me of old-school CSG in raytracing
This is so cool to render boolean surfaces at real time ! Loved it !
Thats so fucking cool. And I agree that object blending is satisfying as hell. Keep up these amazing videos
object blending would be so useful for blending meshes!
I come back to this video and the one about marching cubes so often. I just love it.
That 2D sphere tracing looks so awesome!
Thank you for being such an amazing and generous person Sebastian!! The world needs more people like you.
4:23 rgb version of what you see when you press down on your eyeballs
Beautiful. Especially the visualisation of the Mandelbrot bulb has some otherworldly beauty to it
Ahh, I see you have discovered the special effects from Annihilation
Was definitely my first thought too; was such a cool effect.
What do you mean
@@Zi7ar21 The movie Annihilation. The alien object looks almost exactly like the mandelbulb.
@@ShimrraJamaane I just searched for the scene and it appears that it is indeed a mandelbulb, with some transformations applied to it
@@Zi7ar21 I'm glad I now know the name for what that thing is. I want to render an hour long version of that and use it for my Zoom background :)
By far the most easily understood Ray Marching video I've seen! I love the was you showcase code examples in a non-intrusive way, but still enough to get a basic understanding,
4:30 this looks like the extra terrestrial being from Annihilation
It does! That movie was awesome
I was looking for this comment! I know the visual person or whoever made a lot of the shapes very mathematical. Like the flowers and the mold were fractals. So I bet it was planned and the alien was that shape!
That extra terrestrial being was based on the mandelbulb! Same thing

02:49
HOLY VOLUMETRIC BOOLEANS
OMG
THIS IS BRILLIANT
I have completely lost on that pythagoras!! You sir are awesome! Keep up the good work
The eerie music was from one of my favourite games, Mindustry! **happiness noise**
Realy?! I didn’t even notice!(also very happy I found a fellow comrade here)
Woah, Sebastian! 8D
Most of the images in this video were incredibly satisfying!
Thank you so much for diving into these adventures, and for sharing them with us
so.. after ray marching comes ray jogging? ray sprinting? ray marathon? ray expedition racing?
ray podracing
Ray cross country.
The fact that, all this stuff is done though code is itself mind blowing..
You could use the subtraction technique at 2:47 for making your clouds interact with the mountains and not go through them
I don’t understand how you can make a video that cool looking, yet at the same time super informative... And it’s just 5 minutes! That is really impressivez Thank you.
OMG just imagine the "3D Mandelbrot" thing implemented for VR! It would be trippy af!
I'm still relatively new to programming and these coding adventures are refreshingly creative. I'm loving every second of these. Can't wait for the next one.
The 3D Visualisation of the Mandelbrot set reminds me of the film, Annihilation.
WARRRPP warp warp bum BRRRUUUUUM
Very clean format. One of the easiest to listen to youtube tutors as well. Keep up the excellent work
4:33 Dormmamu, I have come to bargain
Awesome video dude. I love how you include all those steps, the many visualizations, the stuff you played around with (like 3:49).
4:21 it the furnucking thing from annihilation.
that what i wontet to say
I watched this a long time ago but recently started learning ray marching and omg this made things make so much more sense
You already had my like when you put Pythagoras tapping away at a laptop
I've only recently started in unity and learning coding. It's wild how only a short time ago I didn't understand most of anything you were talking about for code, or what I was seeing, but I thought things were interesting. Now I get little inklings of clues as to what is going on.

"I messed around with it for a little bit"
*do something I really need to improve my gaming development skills in such an easy way*
You're an inspiring person my man, I'm not on this level of coding but the things you do just captivate me. Love to see more of these videos maybe even longer videos either way I'm here and entertained
Congratulations. You can now apply to become a visual effects artist for Marvel. That mandlebulb looks exactly like the quantum realm!
NO! If a recruitment agent gets him, no more this kind of videos. Company secret. Fuck Marvel and CGI studios!!! For someone is a lifetime opportunity and for others is slavery to trade secrets and other corporative BS. A similar thing happened to some YT channels.
amazing stuff, have to try it myself! The use of the distance function, to show/hide intersections of two objects, blew my mind
Man, I love raytracing, even if it isn't computationally viable (yet)
But keep in mind that this is NOT raytracing, this is raymarching, they are not the same. Both are awesome though.
@@GameGonLPs Arguably ray marching is more expensive.
these visualizations were amazing for helping me understand ray marching. thank you!!
1:21 "we'll start by calculating distance to the scene". What does that mean?
I think is the distance from your point to the nearest point in the scene.
@@diegomendes1998 Yup, for a given 3D start point and direction (ray), you have a function that returns the distance to hit (distance function).
Omg! These raymarching simulations are pure gold. I really enjoy every single video of coding adventures.. keep it up Sebastian
What tools/frameworks does he use?
it probably isn't too hard just to do a really basic opengl renderer and throw in imgui, with some inputs hooked to shader constants--then again raymarching is all in the fragment/pixel shader (whether you're an opengl or d3d guy!!)
If you wanna get started on raymarching you can use shadertoy.com -- it sets up all the opengl stuff behind the scenes and lets you just write fragment shaders

I'm a simple man.
I see 3D fractals, I click.
Amazing Sebastian! I'm glad I stumbled across your videos! You have sparked creativeness in my brain! I hope to show you something you have inspired some day!
It makes me sad that I will never be able to play with the shapes from 3:18 because it is physically impossible
That is just about the single best explanation of ray marching I have ever come across. Very well done!
Watched this video like 5 times and I'm still trying to understand it
I recently started using MagicaCSG, a SDF-based modeling tool, and this helped demystify it for me, thanks!
that object blending is SO COOL
BEST video on SDF and Ray Marching, so clear and easy to follow, thanks!
maaaan you are one of the best mentor n thinker ive seen on youtube !! thanks aloot man these stuff are really wholesome !!
i got a question wich version of unity do u work with ??
This is my most anticipated video series. Keep up the great work Sebastian!

Thank you Sébastien for helping love math again!!!
My jaw dropped at the object blending, and then you completely blew my brain out with the mandelbulb visualisation! So simple, yet so beautiful.
Your channel is a total gem. Subscribed for life.
Just shared this on twitter to explain this to an artist. Thank you for helping!
I really like those coding adventures! So interesting to watch! keep up the good work
