OpenGLEAN: A leaner GLUT

The hope of this page is to clarify OpenGLEAN's position by giving the official OpenGLEAN view of OpenGLEAN.

In late 2004, Richard Rauch created OpenGLEAN as a fork off of OpenGLUT.

The name is meant to suggest "lean", in contrast to "gluttony". Though "gleaning" also means to "collect bit by bit", especially used of picking through harvested grain. This second meaning is also apt, as OpenGLEAN is trying to separate the "grain" from the "chaff" in the API.

Some very significant portions of the GLUT API, as received from OpenGLUT. are destined for removal. Any of several reasons can be the cause of removal:

• Obsolescence. A few GLUT---and more recent freeglut and OpenGLUT---features are of dubious use now.
• Off-target for the OpenGLEAN core function. OpenGLEAN wishes to focus on providing a solid foundation for window-based OpenGL applications while hiding the OS-dependant details. Many API features have little or nothing to do with window systems.
• Poor API design or fractured implementation. The worst API feature that OpenGLEAN inherited was glutMouseWheelFunc(), as it was known broken before it was adopted and implemented. The next worse feature is probably gamemode which bundles several loosely related features under one API call and which has historical partial implementations.

So OpenGLEAN is seeking to winnow the API.
