For Dr. Brittany Fasy
Once in root directory, type: mkdir build
cd build
cmake ..
make
./greatsphere
It should take roughly 10 min for the sphere to compile. To make the image look sharper, add in more triangles in main.cpp (in the sphere constructor, look for comments in code).
Unfortunaytely, this takes a bit to render and also look nice.
One may zoom in and out on the sphere using '+' and '-', and rotate the sphere using 'u', 'i', 'o', 'p', '[', '['.
