MVP Transform Visualizer

"The engines don’t move the ship at all.

The ship stays where it is and the engines move the universe around it."

— Futurama

This project is a C rewrite of @diskhkme's MVP Transform Visualizer with additional features, for the "Computer Graphics" (1214-3005) course at Chungnam National University.
