GLUT is a window system independent toolkit for writing OpenGL programs. It implements a simple windowing API, which makes learning about and exploring OpenGL programming very easy. . GLUT is designed for constructing small to medium sized OpenGL programs, however it is not a full-featured toolkit, so large applications requiring sophisticated user interfaces are better off using native window system toolkits like GTK+ or Motif. . This package contains libraries, and headers suitable for software development with GLUT.
