What’s amazing is how ray tracing actually dates back to 1982-1984 when the first 3D animations utilising ray tracing were produced and at the time it took hours to render each frame and they needed custom multi million dollar graphics supercomputer mainframe systems that were developed and designed by PHD holding computer scientists so the first animations utilising the technology were primarily tech demos and experimental/abstract/artistic in nature but by 1984-85 a large majority of 3D animated TV commercials were utilising the technology. However additional advancements in 1985-87 allowed for much more complex forms of ray tracing including transparent glass textured polygons with extremely realistic limited opacity reflections that could also be colour filtered to match the colour and texture of the glass itself! Also ray marching was also experimented with as early as the late 1970s as the technique was most likely utilised for the movie Tron that came out in 1982 and the technique allowed them to create extremely large and seemingly complex repetitive scenes with a surprisingly low level of hardware power used which still was a lot at the time due to how it utilised the full capabilities of the hardware to accomplish it! :)
@@thecianinator If that movie was from the 1980s then they would of definitely used a graphics supercomputer for the knight but I believe the scene itself was still shot on film in a studio or on location! :)
I love how when you have a repeating space like in the thumbnail, the object's reflections conspire with perspective to give a sort of harmonics effect. Also, your channel is fantastic (I can't even code, but it's fascinating!).
i've never actually ever seen anyone make fractals so beautiful, well done it's like this should be in some trendy game, it feels like you're in a VR computer world
Some fractals have hollow chambers inside, which work fine. But if you're inside a solid area, all rays 'converge' after 0 steps at their origin, so every ray has 'hit' the same point and the whole screen is just a solid color. Interestingly, color is defined for EVERY point in 3D: surface, inside, and outside. So when you slice a fractal in half, the interior usually contains cool patterns or more fractals in the texture itself. So even though you can't see anything in 3D, the 2D slices are still really cool!
Technically, Marble Marcher allows you to do this when you move the camera inside the fractal. Here's a little animation, though that fractal doesn't have an interesting interior: codeparade.itch.io/marblemarcher/devlog/62680/update-1
For some objects the distance function can allow negative values, but it's not the case for generalized distance marching. Same goes for derivatives of the distance function, which would be very useful if calculable for everything but don't integrate generically for this technique. Maybe @CodeParade uses negative distances in his little game where a transparent glass marble rolls on fractals. Using that you can march inside the marble and get refraction etc.
I was learning ray marching a while ago and made a field of spheres like in the thumbnail. Then I added a sound library so I can play mp3s and made the spheres pulsate to the beat. Just made my own 3D sound visualizer that way
Wow. Looks trippy. A side note to your brief on Ray marching. Ray marching uses Signed Distance functions, a simple Euclidean distance estimator, the Euclidean norm will be calculated. Also it would be great if you had given a precursor to Recursive primitives. Great video. Big fan.

Your video is just beautiful. 4:01 I can imagine flying around in VR for hours. same goes for 6:45. Fractals looks so weird for us, its like, we are looking something really new for the first time in human history! keep it going with this video!
in 6:45 all those structures are fractals right? It really shows that not all fractals are self similar It keep my thinking, is posible to use Fractals to simulate molecules interactions? Like having a algorithm that works on a protein structure and transform it to a fractal, then works It out with Fractals to bind It to other Protein structure. so when you have a match you transform It back to proteins structure. You then would you have a protein that can bind to the second protein. If it works It woud really help to make antibiotics or other biological stuff in general I am notsure If this makes sence, but I just saw It on my head watching your video!
Thing is,this is really easy to compute from what I grasp from the video. Your card would probably be taking you out for a drink on the house after using this kind of rendering
Minecraft is literally the only game that still uses straight up quads through the ancient GL pipeline instead of triangles, fun times when you're dealing with undefined behaviour. Great video :)
Ray marching, you say? Super interesting. While stydying CS I got really inspired into trying to write my own 3D engine. I thought I had come up with a somewhat complete picture of the basics, but apparently there were some things I haden't thought of. For rendering my first intuition was what you call ray marching. But I did it the naive way. I quickly realized this was unrealistic, so I googled ways to check line intersections and landed on ray tracing and that's where I stopped. The engine runs in maybe 30 fps but at a fifth of HD-resolution and without any bells and whisstles. Now I really feel like picking this up again and trying your version of ray marching, or alternatively going for the conventional rastering.
Please make a VR version that allows us to easily tweak the math bits and change formula. Fractals in VR are mind-blowing, but there's been only a few programs made. Only the one that allowed for serious transformations was made for the Oculus DK2 over 5 years ago.

Mind-blowing since the moment you started talking about grafics, actually. Though I am rather impressed, that someone can be so good at talking about that. Maybe I am not clever enough to understand that, but you definetely got a like and a sub for uploading this video on TH-cam.
Raymarching is probably a better “3D version” of raycasting than raytracing, since raycasting only checks for ray intersections at the places where they could be (at the edges of cells in the map) instead of testing for intersections with every single cell in the map, similar to raymarching
I think the most disappointing part about ray marching is, that while the algorithms and techniques to calculate the distances, reflections, shadows and geometry are super efficient while looking very realistic, it's virtually impossible to create realistic looking scenes with it, at least when trying to render in real time.
It’s amazing to think that while during a strong psychedelic trip your brain can do all this rendering instantly without even thinking about any of the math it just creates these amazing fractals
