Quartz Composer uses (including ), (only in Mac OS X 10.6 and later),,,, and other technologies to create an and a developer tool around a simple visual programming paradigm.
Apple has embedded Quartz technologies deeply into the. Compositions created in Quartz Composer can be played standalone in any -aware application (although only on Mac OS X 10.4 and later), as a system, as an iTunes Visualizer, from inside the Quartz Composer application, or can be embedded into a or application via supplied. While Quartz Composer is included with the iPhone SDK, as of December 2015 there is no way of running Quartz Compositions on devices. Contents • • • • • • • • • • • • • • • • • • • • • • Patches [ ] Quartz programming through Quartz Composer works by implementing and connecting patches. Similar to routines in traditional programming languages, patches are base processing units.
They execute and produce a result. For better performance, patch execution follows a approach, meaning that patches are only executed when their output is needed. There are three types of patches: Consumers, Processors, and External Input patches that can receive and output mouse clicks, scrolls, and movements; and audio; keyboard; or other movements.
Nov 15, 2015 This short tutorial explains how to use a custom Quartz Composer patch I wrote called 'Contours'. You can download the patch.
A collection of patches can be melded into one, called a macro. Macros can be nested and their subroutines also edited. To control the order of rendering, each renderer is assigned a layer, indicated in its upper-right corner.
Layers are rendered sequentially, lowest to highest. Renderers can be enabled or disabled, essentially turning on or off that particular layer. Turning off unused layers often results in better performance, since fewer upstream patches need to be evaluated. Some patches can have subpatches, which allows for global parameter changes to just the included subpatches. This is useful for lighting, 3D transformation, and shaders, among other things. Subpatch support is indicated by square corners on a patch, rather than the typical rounded corners. With Version 3.0, it became possible to turn compositions into Virtual Patches.
These allow the user to reuse functionality without having to store duplicate copies in each composition. The Quartz Composer Editor allows the user to save a 'flattened' copy (with the virtual patches fully expanded inside), for easy distribution.
Version 4.0 extended this functionality even more, and automatically includes 'flattened' copies of virtual patches for use as a fallback if the desired virtual patch isn't installed on the host system. This greatly simplifies composition distribution. Network functionality was greatly improved with the release of Leopard. It became possible to transmit data and synchronize over a network interface, and it also added support for transmission and reception. The Quartz Composer 3.0 interface. Also new in Version 3.0 was the possibility to write custom patch plugins, using an template, and the notion of a ', where plugins and other unsafe patches fail to load. This prevents malicious compositions from performing dangerous or insecure operations.
