Processing is a Java library for working with computer graphics, providing methods by which to draw primitive objects, custom meshes, etc., as well as mathematical methods (such as Simple Harmonic Motion) by which to animate and control them.
How can you achieve similar graphics capabilities in the Unity Game Engine?
Suppose, for example, I wanted to build a game like Duet. I can imagine how I might go about creating those graphics in Processing or p5.js, but not in Unity and C#. How can you have that kind of creative freedom to build and draw in Unity?
