Quartz Composer is a node-based visual programming language provided as part of the Xcode development environment in Mac OS X for processing and rendering graphical data.
Quartz Composer uses OpenGL (including GLSL), OpenCL (only in Mac OS X 10.6 and later), Core Image, Core Video, JavaScript, and other technologies to build an API and a developer tool around a simple visual programming paradigm. Apple has embedded Quartz technologies deeply into the operating system. Compositions created in Quartz Composer can be played standalone in any QuickTime-aware application (although only on Mac OS X 10.4 and later), as a system Screen Saver, as an iTunes Visualizer, from inside the Quartz Composer application, or can be embedded into a Cocoa or Carbon application via supplied user interface widgets. Because Quartz Composer makes extensive use of hardware acceleration and pixel shaders, it is recommended to have a graphics card with at least 32 MB of VRAM. While Quartz Composer is included with the iPhone SDK, there is currently no way of running Quartz Compositions on iOS devices.

Famous quotes containing the word composer:
“Whenever [Leonard Bernstein] entered or exited a country he would fill in on his passport form not composer or conductor, but musician. Of course people in the press spent a lot of Lenny’s life telling him what he should have done; he should have been a concert pianist, he should have composed more.... And people wouldn’t let him live his own life. But he created his own career, in his own image.”
—John Mauceri (b. 1945)
