I have made this rotating cube from scratch, too learn more about C. I have always been fascinated by 3d computer graphics, which I usually do in WebGL and JavaScript. But since I am learning C, I tried to do this.
Make sure you have make and some c compiler and simple run:
make
and then run executable with the width of characters as argument.
./build/draw_cube 40
Note: If you input a large value and the cube does not fit the screen, make sure to resize your terminal.
