#raymarching — Public Fediverse posts

🚀 Ah, the riveting saga of Jax's "true calling"—because nothing screams excitement like ray-marching renderers on #WebGL. 🤯 It's like the author stumbled upon a new toy and decided to write a love letter... to themselves. 🎨 I can hardly wait for the sequel, "Jax: The Revenge of the N-dimensional Arrays."

Welcome to #TextModeTuesday! For the next few weeks I'll be posting some projects & experiments related to this just spontaneously made up hashtag. If you've got something related to interesting text-based art/experiments, patterns, ASCII-art, ANSI-art etc. please share — the more, the merrier...

To start with, here's an experiment from a few years ago to demonstrate some capabilities of https://thi.ng/text-canvas and https://thi.ng/shader-ast to create a raymarching renderer outputting images in text mode (with customizable character sets to represent luminance).

Demo:
https://demo.thi.ng/umbrella/ascii-raymarch/

Commented source code:
https://github.com/thi-ng/umbrella/blob/develop/examples/ascii-raymarch/

Hotkeys:

- c = toggle color on/off
- t = toggle theme switch
- space = toggle update

WebGL version of the same scene (using an almost identical TypeScript shader source, only here transpiled to GLSL and using slightly different colors):
https://demo.thi.ng/umbrella/shader-ast-raymarch/

"Several hours later.."

Okay! I think I got it down now! The key was limiting maximum step size for the raymarcher to a constant value, and doing a proper square falloff for the light intensity! 👍 😃

I'm playing a bit with glow tracers, trying to figure out the mathematical theory behind, but it's crazy how sensitive they are to the parameters.

Рендеринг трёхмерных фрактальных множеств: от губки Менгера до Мандельбокса, часть 2

Привет, Хабр! Меня всё также зовут Андрей Гринблат, и в первой части я начал рассказывать о такой технологии, как ray marching, и о нормированных пространствах. В этой части начнём с построения простых геометрических фракталов — губки Менгера и тетраэдра Серпинского, затем построим IFS-фракталы, рассмотрим технику орбитальных ловушек, и в завершение построим фрактал «Ящик Мандельброта», или Мандельбокс.

Created using raymarching, the ray paths are distorted the closer they get to the black hole.

The box cut is not perfect but we're getting there!

Edit: also, fun stuff, I realized I could return transparent pixels, so the web page background takes over and it looks like the shape is floating on it. It's stupid but I love it :3

Dear #shader #graphics #programming community:

Where is the rendering error on my raymarched sphere grid coming from?

Farther away spheres distort in circular patterns when stacked. Dunno if it's caused by space repeating function running out of accuracy, and far away grid components starting to count in..

But it's kind of hard to do a grid without a repeating function!

Any ideas appreciated.

🎨🤓 Ah, the gentle art of turning math into paint! This is a delightful tale of one person's quest to understand the sorcery of raymarching—because who needs actual geometry when you can just throw formulas at a screen and hope for the best? 💻✨

Very cool read! A novel (to me and the author at least) approach to computing recurrence for iCalendar rules.

Made my own tiny wgpu raymarcher: https://codeberg.org/wesfly/wgpu_raymarching. Built with Rust + wgpu + WGSL shaders. Features real-time SDF scene, smooth object blending, camera controls, and FPS limiting. I'm still working at it. 🧑‍🔧

🎉 Who knew #iCalendar was the secret sauce to ray marching? 🤔 Spoiler: It's not. Just another riveting tale of a developer entangled in the 'exhilarating' world of 1998 tech. 🔍✨
