Notes

• Written by David Cardona for Michael Shah's 3D Graphics course at Havard Extension School, Fall 2020.
• This project is written in C++, OpenGL, and SDL.
• A demostration/explanation can be found at: https://youtu.be/Cu3k_METjzA

Compiling Instructions

• Compile by going into the 'sine_visualizer' directory, and running build.py
  • Note that this project requires C++17 and uses the GNU compiler (g++). This can be changed in the build.py file.
