Woven fabric visualization
I've been working on a 3D visualization of weaving, and because it's complex I realized breaking it down into pieces would be beneficial. So this is a 2D visualization of woven fabric, using d3...

Exploring CSG using THREE-CSGMesh
Constructive Solid Geometry is a method of creating complex shapes by adding and subtracting simpler ones. There are few CSG libraries for use in the browser: https://evanw.github.io/csg.js/ Simple...
Has anyone tried to algorithmically design a color scheme for syntax highlighting? Idea: things that commonly appear close to one another should be the farthest apart in terms of their colors. It can be framed as an optimization problem, based on training data.

Calculating normals for distorted vertices
When we move vertex positions in a vertex shader in non-linear ways, how do we compute correct normals for the resulting surface? One method I found is discussed here https://community.khronos.org/...
Just published an experiment with generating sharp text for use in webgl: observablehq.com/@k9/generating… Built with @observablehq and regl.js

Generating Signed Distance Text
To show text in WebGL, we can render it to a canvas like this one, and use the canvas as texture: But as you can see in the "Simple Texture" column of the demo below, this approach results in text...
