portable API for OpenGL graphical interfaces
Pugl is a minimal portable API for OpenGL GUIs which supports embedding and is suitable for use in plugins, but can also be used for programs. . Pugl is vaguely similar to GLUT, but with some significant distinctions: * Minimal in scope, providing only what is necessary to draw and receive keyboard and mouse input. * No reliance on static data whatsoever, so the API can be used in plugins or multiple independent parts of a program. * Single implementation, which is small, liberally licensed and suitable for direct inclusion in programs if avoiding a library dependency is desired. * Support for embedding in other windows, so Pugl code can draw to a widget inside a larger GUI. * More complete support for keyboard input, including additional “special” keys, modifiers, and support for detecting individual modifier key presses.
