=== HOW IT WAS MADE ===

This video is a "demo" application, written in Forth (the best programming language ever!), rendered using the Simple Direct-Media Library (SDL), and encoded into video format using Libx265.
I use the "gforth" implementation of Forth, since it is quite fast and has a nice protocol for interfacing with the C language. I wrote my own graphics engine from scratch in order to ensure the program simulates an infinite plane properly and efficiently. Everything is calculated using 2D trigonometric functions and step algorithms -- the program does not use any 3D vector math. After each frame is rendered, it is converted from RGB to YUV color space and sent to Libx265 for encoding into a raw video stream. Lastly, the music file was added to the stream and converted to MP4 format using ffmpeg.

Unfortunately, GabTV re-encodes videos when they are uploaded, which results in a slight loss of quality. That's why this video looks "grainy" in a few places, but there's nothing I can do about it. Ah well.
