Jitter, a software package first made available in 2002 by Cycling ’74, enables the manipulation of multidimensional data in the context of the Max programming environment. An image can be conve- niently represented by a multidimensional data ma- trix, and indeed Jitter has seen widespread adoption as a format for manipulating video, both in non- real-time production and improvisational contexts. However, the general nature of the Jitter architec- ture is well-suited to specifying interrelationships among different types of media data including au- dio, particle systems, and the geometrical represen- tations of three-dimensional scenes. It can draw hardware-accelerated graphics using the OpenGL standard.
