Cymatics in TouchDesigner
Cymatics are an amazing phenomenon created by resonant waves, which cause sand or other small particles to form beautiful, self-organized patterns. A very common example of cymatics are Chladni plates, a special case of this cool effect! In this tutorial, we will first understand what cymatics are and how they function, then use simple math and GLSL shaders to implement an interactive version of the system in TouchDesigner! Finally, we will create a lightweight particle system (from scratch) that will be used to render our patterns, and make it audio-reactive :) Paul Bourke Website: https://paulbourke.net/geometry/chladni/ Find me online!
