Quartz Composer is a node-based visual programming language freely available to registered Apple developers for processing and rendering animated 2D and 3D data.

Quartz Composer uses OpenGL, OpenCL (only in Mac OS X 10.6 and later), Core Image, Core Video, Core Audio, JavaScript, and other technologies to build an API and a developer tool around a simple visual programming paradigm. It used to be part of the Xcode development environment in macOS but is now a separate download named Additional Tools for Xcode.
