Thank you so much for this! Most don't touch glsl in td. Love it!

Thank you so much for this tutorial!

I am just starting to dip my toes into both Touchdesigner and Shaders. I have already read some articles and watched some videos and other tutorials. With your help I understood for the first time how shader code outputs each pixel simultaneosly and constantly and why we would need to manipulate 4- and 3- and 2-dimensional vectors.

I'm glad I finally found a tutorial that covers these very basics! Most other tutorials glance over the basics way too fast or are just not made for absolute newbs but yours was exactly the right level for me. Thank you for sparking my excitement! 💥 BOOM

Thanks for the great tutorial. Can you explain why you need to enable the export flags on your LFO CHOPs @13:33 in the tutorial?
