Adventures in 3D Printing

I shamelessly stole whole idea from Robert Cupisz and did some 3D printed earrings. TL;DR: raymarching, marching cubes, MeshLab. Now for the longer version… Step 1: pick a Quaternion Julia fractal As always, Iñigo Quilez’ work is a definitive resource. There’s a ready-made GLSL shader for raymarching this fractal in ShaderToy (named “Quaternion”), however current state of WebGL doesn’t allow loops with dynamic number of iterations, so it does not quite work in the browser.
