Hi @jshaw3 – were you able to resolve this issue? I am not a GLSL expert, but the ShaderToy porting guide / example in this thread might be helpful:

> A few years ago, I wrote an example on how to port GLSL shader code from [Shadertoy.com](http://Shadertoy.com) to Processing. Since then, Shadertoy has changed quite a lot (adding a lot of new uniforms and input methods) so an update was long overdue. You can find it here: [https://github.com/SableRaf/Shadertoy2Processing](https://github.com/SableRaf/Shadertoy2Processing) There is still work to be done, but it should be a good starting point for anyone wanting to learn about shaders from the great material available at Shadertoy, and experiment with it in Processing. …
