Intro:

This code base was created as part of my undergraduate course 
Computer Graphics (CS475) - https://www.cse.iitb.ac.in/~paragc/teaching/2017/cs475/

Notes:

1. OpenGL is a large state machine
2. Macro view of working:
    (create context -> change options -> render the context)

Dependencies:

sudo apt install libglew2.1
sudo apt install mesa-utils
sudo apt install freeglut3-dev
sudo ln -f -s /usr/lib/x86_64-linux-gnu/libGLEW.so.2.1 /usr/lib/libGLEW.so.2.0
sudo apt install libglfw3-dev
sudo apt install libglew-dev
