I drew these corals with mathematical equations
- gus_massa 3y agoObligatory nitter link: https://nitter.net/naderi_yeganeh/status/1690296100496838656 https://nitter.net/naderi_yeganeh/status/1690296100496838656 More images in https://twitter.com/naderi_yeganeh https://twitter.com/naderi_yeganeh In another xtter, he posted a link to a blog that explains how he finds the equations. It's a general discussion with example, not a specific discussion of the corals. https://blogs.scientificamerican.com/guest-blog/how-to-draw-with-math/ https://blogs.scientificamerican.com/guest-blog/how-to-draw-...
- mutant_glofish 3y agoVery cool! This reminds me of the guy 3D modeling a selfie-girl with math equations: https://www.youtube.com/watch?v=8--5LwHRhjk https://www.youtube.com/watch?v=8--5LwHRhjk
- fasterik 3y agoIndeed, Inigo Quilez is "the guy" for this kind of stuff. He co-created ShaderToy and has worked on effects and modeling for multiple Pixar films. My favorite video of his is Painting a Landscape with Maths. https://www.youtube.com/watch?v=BFld4EBO2RE https://www.youtube.com/watch?v=BFld4EBO2RE He deserves to have at least as many subscribers as other math YouTube channels like Verisatium and 3Blue1Brown.
- paulpauper 3y agonot quite the same thing. piecing together parts with individual equations, like a mosaic, not the same as modeling the whole thing with a set of huge parametric equations
- pphysch 3y agoIt is one big equation, he just isolates each piece to better explain it
- modeless 3y agoIf you think that's cool you'll like this guy's equations too. Written in GLSL so they run in your browser in real time as well. https://x.com/zozuar https://x.com/zozuar And, of course there's also the classic Shadertoy https://www.shadertoy.com/results?query=&sort=love https://www.shadertoy.com/results?query=&sort=love
- distortionfield 3y agoDoing this inside the character limit is blowing my mind rn
- omoikane 3y agoThat's what I was thinking as well -- these are equations that generate colors in 2D space, so essentially pixel shaders, but for this particular effect I wonder if it would be simpler with some geometry shaders, and have a 3D engine take care of the shadows.
- ranting-moth 3y agoThere's something in many of those those Zozuar animations that trigger what I'm sure is a primal fear with me. Fascinating stuff but some of it is terrifying.
- mensetmanusman 3y agoIt’s non-stop uncanny valley.
- Aardwolf 3y agoPerhaps because biological creatures themselves can exhibit complex shapes and patterns through simpler mathematical principles like fractals and cellular automata
- Angostura 3y agoCame here to say exactly that. Fascinating, but deeply unnerving for some reason.

- Almondsetat 3y agoThis looks very similar to Apple's "Drift" screensaver from macOS Catalina [0], which is also calculated in real time. [0] - https://www.youtube.com/watch?v=7WXzRhebz1g https://www.youtube.com/watch?v=7WXzRhebz1g

- goodbyesf 3y agoThat's the basis of ancient greek mathematics which used the world as the model of its mathematics. So if twitter was around in the ancient greek world: 'OP derived these mathematical equations from these corals'.
- chubbnix 3y agoIt looks a lot like a H. magnifica anemone’s tentacles.

- stainablesteel 3y agohe's got a lot of these it seems to me like he's deriving the equations from images that he finds, then using the equations to generate new images with a stroke of randomness.
- SomewhatLikely 3y agoThat would be far more impressive if true. The equations while having a number of magic numbers also don't have that many parameters, so it would seem difficult to find such equations to fit well to images.
- anon____ 3y agoHere's a quine in a similar fashion: https://en.wikipedia.org/wiki/Tupper's_self-referential_formula https://en.wikipedia.org/wiki/Tupper's_self-referential_form....
- taneq 3y agoI don't think this is quite the same fashion, the original post looks like the geometry is being generated by the equations while Tupper's formula directly stores a bitmap image in the coordinates.
- mrob 3y agoMisleading name. It's not self-referential at all; it's just a simple bitmap renderer written in mathematical notation. The actual bitmap is stored separately.

- paulpauper 3y agofinally a twitter user that is: a real person not posting about politics or crypto (which probably refutes the first criteria)
- spoonjim 3y agoVery cool!
- uwagar 3y agothis is great and all but the way of mathematical equations isnt quite the way of the computer. its kinda like hardcoding with magic numbers. on the computer you want to model the processes that makes the coral and then let the computer unfold it and hopefully it produces your coral. more interestingly, it will produce other shapes nature hasnt thought of yet.
- larodi 3y agoL-Systems, in my opinion, are much more simple, expressive and easy to understand, and actually can result in very similar structures. There's also the CFDG/Context Free (curiously by Chris Coyne) system which allows grammar-based inference which produces structures sembling bioforms, also very straightforward. Also continuation of this reasoning is Structure Synth... https://www.generativeart.com/on/cic/GA2009Papers/p17.pdf https://www.generativeart.com/on/cic/GA2009Papers/p17.pdf
- niknoble 3y agoWay too many parameters to be interesting. Talk about fitting an elephant.
