OpenGL application that renders a sphere in a skybox using football related textures. The sphere is generated using quads split vertical stacks and horizontal sectors, the number of which can be controlled by command-line arguments.
Keyboard arrows can be used to move the camera, and the mouse can be used to look around. The position of the camera, along with the FPS, is displayed at the bottom left of the screen.
Some basic phong shading is done, but there are no more advanced techniques like shadows.
Usage: ./glsphere
OpenGL implementation of a sphere in a skybox.

The external directory contains the following dependencies as git submodules
which are built as part of the project:
- freetype
- stb
- glew
- glfw
- glm
$ cd <path/to/source>
$ cmake -S . B build
$ cmake --build build
