Coding Adventure: Ray Marching

In this coding adventure I explore ray marching and signed distance functions to draw funky things!

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.

That pythagoras animation had me in tears

[CodeParade]

Your visuals are so nice looking! I'm interested to see what else you do with ray marching :)

[BlukBlukGames]

I really like this format of videos. As usual awesome

[slavcabbage]

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.

those 2d visualizations showing how the algorithms work are awesome. (the rest of the video too)

[bjarnes.]

This format made me activate the bell. Keep up the good work!

[Jabrils]

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?

Some technique like this one was used on the movie “Annihilation” for the alien life form, pretty spectacular

I don't understand anything in this video
But still enjoy it

[momoaraki]

You are amazing teacher. I love how you focus on foundational functions to express conditional intersections and blends!

[kristinawaldt]

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.

[Hyuts]

Thank you for being such an amazing and generous person Sebastian!! The world needs more people like you.

[jonathanravenhilllloyd]

It feels so good to hear you say "I have no idea how the code works, but..." :D

[Jejkobbb]

Thats so fucking cool. And I agree that object blending is satisfying as hell. Keep up these amazing videos <3

4:30 this looks like the extra terrestrial being from Annihilation

[Vrsen]

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,

Absolutely mind boggling! This kinda reminded me of old-school CSG in raytracing

[jaugretler]

Beautiful. Especially the visualisation of the Mandelbrot bulb has some otherworldly beauty to it
