Easy GLSL Chromatic Aberration in TouchDesigner - Tutorial
Get access to 200+ hours of TouchDesigner video training, a private Facebook group where Elburz and Matthew Ragan answer all your questions, and twice-monthly group coaching/mastermind calls here: http://iihq.tv/Trial If you’re a TouchDesigner Beginner, check out our TouchDesigner Tutorial Series! We teach you all the basics of how to use TouchDesigner, including mouse controls, hotkeys, parameters, the operator families, and more: https://interactiveimmersive.io/touchdesigner-tutorial/ Chromatic Aberration is a cool and commonly used visual effect to add some variety and vintage vibes to clean textures. It’s also very easy to emulate in GLSL! In this video, Jack DiLaura walks you through creating a GLSL pixel shader in TouchDesigner that allows you to independently shift and scale the red, green, and blue channels of a TOP texture. The shader allows you to create subtle chromatic aberration-style color shifting, along with more extreme and experimental effects. You’ll work through some of the basics of working with GLSL in TouchDesigner along the way, taking a look at common terminology, functions, and controlling aspects of the shader outside of the GLSL code itself.
