Timestamps:
00:00 Introduction to the Challenge
00:46 What do we need to do?
02:14 Draw a rectangular grid!
04:13 Create a flat triangle strip mesh!
06:51 Rotate the surface in 3D!
08:47 Set the z-values of the vertices randomly!
11:04 Create a 2D array to store the z values!
13:31 How do we make the terrain infinite? 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!
