The Coding Train | 1.5 A Unit Vector (Normalize) - The Nature of Code @TheCodingTrain | Uploaded 4 years ago | Updated 1 minute ago
In this video, I explain the concept of a “unit vector,” what it means to “normalize” a vector, and take a look at the p5.js functions: p5.Vector.mag(), p5.Vector.normalize(), p5.Vector.setMag(). Code: thecodingtrain.com/tracks/the-nature-of-code-2/noc/1-vectors/5-unit-vector
