Advanced Setups 08 - From Paper to VEX: Electrostatic Halftoning
Added 2021-09-30 13:07:04 +0000 UTCSometimes old Algorithms wash up in our feeds, emails and DMs. No clue what’s been going on with this one but we received quite a few questions on how to pull it off. Turns out it is an adaptation of a technique from 2010, called “Electrostatic Halftoning”. It’s not fast but it can generate intricating dot patterns which form an image. The good thing about the algorithm is that it is time consistent, meaning we don’t get all jittered dots when using it on video.
In this tutorial we’ll go over what it takes to take a scientific paper and turn it into a Houdini setup using math, intuition and VEX. You’ve been warned.

Of course we’re late to the party and Junichiro Horikawa covered image stipling here.
