Ports of OpenGL[edit | edit source]

A rendering engine based upon OpenGL designed to work on the web.
A wrapper for OpenGL that works with: C#, VB.Net, C++/CLI, F#, Boo and many more on multiple platforms[1].
Light-Weight Java Game Library.

Libraries[edit | edit source]

The OpenGL Extension Wrangler Library (GLEW) is a cross-platform C/C++ library that helps in querying and loading OpenGL extensions[2]. Note that GLEW is open source[3].
OpenGL Mathematics library, comes with mathematics code for vector, matrices etc.
The OpenGL Utility Toolkit (GLUT) is a library of utilities for OpenGL programs, which primarily perform system-level I/O with the host operating system. Functions performed include window definition, window control, and monitoring of keyboard and mouse input[4]. Note that GLUT is not open source[5].
Qt is a cross-platform application and UI framework for developers using C++ or QML, a CSS & JavaScript like language[6].

Glut open-source alternatives[edit | edit source]

Cpw is an application framework library for OpenGL applications and games modeled after the GLUT API. It is designed with speed, simplicity, and portability in mind[7].
FLTK provides modern GUI functionality without the bloat and supports 3D graphics via OpenGL and its built-in GLUT emulation[7].
Open source and extended alternative to GLUT that allows the user to create and manage windows containing OpenGL contexts on a wide range of platforms and also read the mouse, keyboard and joystick functions[7].
Open source, portable framework for OpenGL application development with a link library for handling operating system specific tasks, such as opening an OpenGL window and reading keyboard, mouse and joystick input[7].
C++ wrapper for GLUT, providing a fully object-oriented API for creating windows, menus and other GUI elements, and for event handling[7].
GLT can be used as an object oriented interface to OpenGL, or as a library of pre-canned functionality for transformations, shapes or fonts, etc. GlutMaster is a C++ interface wrapper to GLUT, providing a portable window, keyboard, mouse and menu environment for OpenGL programs[7].
GLUI is a GLUT-based C++ user interface library which provides controls such as buttons, checkboxes, radio buttons, and spinners to OpenGL applications. It is window-system independent, using GLUT or FreeGLUT[7].
NGL is an application framework similar in many ways to GLUT, but with many enhancements in order to make it an easy and yet powerful tool for cross-platform C++ application programming[7].
A cross-platform multimedia library designed to provide level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL, and 2D video framebuffer[7].

Other[edit | edit source]

OpenCL™ is the first open, royalty-free standard for cross-platform, parallel programming of modern processors found in personal computers, servers and handheld/embedded devices[8].
A cross-platform audio API that deliberately resemble those of OpenGL[9].
