Sine and Cosine - Shader Graph Basics - Episode 19

In this shader tutorial, I explain how the sine and cosine functions work and then show 4 shader examples for how to use sine and cosine in Unreal and Unity - including a value that flashes on and off, a bouncing ball, water ripples, and rotating UVs.

The amazing animated illustration of sine and cosine was created by Freya Holmér. Check out here YouTube channel here:
