This is a walkthrough of how to methodically build periodic functions using sine, frac, modulo, and ceil. Rather than just showing equations, this will be a lesson about how to break up a graph into pieces and use other simple periodic functions to create more complex-seeming periodic functions. This will be seen through a lens of materials, so there will be examples such as vertex animation motion and UV manipulation—but the topic is generic enough for anyone interested. The goal is to walk away with the power to think about how to use basic math more creatively.

Superb !
Must watch for every student, beginning TD’S and surfacing artists as well.
Cheers,
