What did you learn?
I watched the Sebastian Lague videos to learn more about how to generate the heightmap with fractional brownian motion. I also reinforced my knowledge by applying concepts I read about from LearnOpenGL.com. I also got carried away and learned some post processing effects, such as learning how to code lens flares. I might try to implement shadow maps and volumetric clouds in the future. I could potentially also try to convert this code into Vulkan in the far, far away future.

How did you improve the terrain?
Yep, so I wanted to improve my OpenGL skills so instead of having the project be in Godot I wrote it all in OpenGL. Additionally, the heightmap and normal map generation happen during initialization. I also used Parallax Occlusion Mapping to make my quad look like it had depth (even though it was only 2 flat triangles). I also added a sun which rises and sets (and it changes color depending on its position in the sky as well as increases or decreases the overall brightness of the scene). I also implemented Blinn-Phong lighting. And finally, I added post-processing effects such as HDR/ tonemapping, bloom, and lens flares.
