Leopard Sample Code
Graphics and imaging on Mac OS X consists of three main developer technologies: Quartz, an advanced drawing engine and windowing environment; OpenGL, an Apple implementation of this 3D graphics industry-standard API; and QuickTime, the cross-platform multimedia technology for handling video, sound, and text.

A guided introduction for developers new to Mac OS X graphics and imaging.   Essential information for developers working with graphics and imaging.   C and Objective-C API references organized by framework.
