Description

In this coding challenge, I create a 3D procedural terrain using Perlin Noise and the beginShape() function in Processing.

What is Perlin Noise? 17:03 How do we make the terrain smooth? 17:43 Reduce offsets to get smoother z values 19:17 How do we make it appear as if we are moving over the terrain? 20:30 Change y-offset per frame to create the illusion of flying! 22:05 Thanks for watching!
