Thanks! First I'm generating the general geometry of the wings - the most basic shape is a "teardrop" / half of the infinity symbol (see this[0]). Then they are scaled and rotated randomly (within a range to match the other parts of the wings), and further perturbed to make the shape more random. Then I'm drawing lines from the "tip" of the teardrop to the edges and using them to color the segments. The final result is rendered with Three.js[1]. Obviously this is a very succinct explanation, it took me quite some work. You're welcome to look at the code[2], though it's quite messy :) [0] https://en.wikipedia.org/wiki/Lemniscate_of_Gerono https://en.wikipedia.org/wiki/Lemniscate_of_Gerono [1] https://threejs.org/ https://threejs.org/ [2] https://github.com/andersource/andersource.github.io/blob/master/assets/proc-butterfly/index.js https://github.com/andersource/andersource.github.io/blob/ma...
