As we looked at in a previous video, GLSL is an incredibly powerful tool for complex simulations, textural effects and post processing. A few lines of code can contain the same functionality that would require a network of nodes in the TouchDesigner network.

Not all GLSL effects have to be hyper-realistic simulations, though — it can be just as useful for creating imperfect, glitchy effects.

In this video, Jack DiLaura walks you through converting a glitchy trailing feedback effect from ShaderToy for use in TouchDesigner. As you work through modifying the code to function in TouchDesigner, you’ll also look at techniques for adding functionality and pushing the effect further using built-in TouchDesigner tools and operators.
