Instancing with TOPs in TouchDesigner

This TouchDesigner tutorial covers instancing with TOPs through the creation of a "particle donut." It's at a beginner to intermediate level, with a more advanced section at the end touching on GLSL.

Worth the watch, learned a lot, thanks!

[@your_chinese_fans]

Your tutorial is very good and it helps me a lot in my study. Thank you very much. I wish you a happy life

[@jun1408]

thx man this help me lot, i learn how do those attractor force whatever in processing, but did not know how it apply into td and how td glsl work, but after u show the node version and text version, i can visualize it now.

[@JennA-od7ut]

you are amazing!

Damn!! 😵‍💫🤩🤩

Amazing tutorial so much information!!
Is there a reason you are using chop export rather than reference?

[@polyhop]

Great question, it mostly comes down to habit for me, since I started using TouchDesigner when exports were still faster than references. At this point python speed in TD has improved to the point that any speed difference is negligible. There are instances where one or the other makes more sense (if you use the export by channel name, or are using expressions dynamically) but I think most instances in this tutorial you can use either interchangeably
