Night Sky Rendering

The matter of this thesis is a rendering OpenGL application written in C++. The application aims to render the sky in real-time, including all its essential features, and can also render the sky at any given moment and from any given location on Earth. The application renders the Sun, the Moon, the stars, the background of the stars and maps the color tones so that the scene would feel more like at night. Additionally, the scattering of light in the atmosphere is approximated, so several further phenomena can be observed in the app, like dusk, dawn, and the blue color of the sky during the day. The user can change the parameters influencing the location of the rendered objects on run-time. The application uses freeglut and glew.
