This website has been created by myself, Miroslaw Artur Rusin (you can reach me at mirek [at] me [dot] com). On the website you will find educational materials related to Quartz Composer – a visual development environment application developed by Apple Inc. You will also find projects created by other people in form of: Snow Leopard - Doodles & Noodles - OpenCL & DAE Meshes. Journal Firstly, I wanted to see just how well some of my old compositions worked in Snow Leopard.
This precipitated a process of pulling plugins that showed they were not pre flighting correctly [ loading at application boot time ], or that now were intercepted as being of an incorrect architecture. The Console application proved invaluable in this , especially as other 3rd party monitoring and feedback plugins were amongst the various plugins pulled. See Pulled & Culled for further details of what didn't actually make it through thus far to QC 4. This process had one extra tier of refinement, namely that code blocks in plugins might well be acceptable at 32 bit, but fail if QC 4 were booted as 64 bit, its Snow Leopard default boot mode.
Until further notice, this differential is likely, under some circumstances, to make for a 32 bit plugin variant to the norm reference 64 bit QC 4 working environment. Click to Play They were then rendered and sometimes iterated as Mesh patch renders. Snow Leopard - QC4 - OpenCL & Quartz Composer 4. What's New The VJ interface, the new programing patches, Open CL & Mesh Renderers, the limiting of currently supported hardware consequent upon Open CL, the support for .dae [ Digital Asset Exchange file format ] , the loss of some 3rd party plugins and patches, a couple of new patches, a better organised patch library, the growing number of Apple's Snow Leopard sample compositions and much more besides.
We can now boot into 32 bit mode, which helps some 3rd party plugins to spring back into life, more details below. It will be interesting to see just when a full 64 bit kernel boot will be default on OS X 10.6.x. Currently we can boot either into 32 or 64 bit kernel and extensions, other extensions and frameworks are either 32 & / or 64 bit capable.

Snow Leopard - QC4 - OpenCL Dev Experiments. Examples Please note, pretty much everything here is based upon code samples from the Developer list or else is using an edited version of a default SL only patch.
What I'm trying to say is play carefully. These items have not been soak tested and proved. All I know is that I can run them on a fairly low end Intel Mac, with a by now pretty much entry level OpenCL capable GPU. I also know that they have been running when crashes occurred and have themselves caused crashes, especially in regards of audio interactivity. It seems to me that iTunes and Quartz Composer are no longer such good bed fellows, although developing audio interactive compositions can be faciltated by running SoundFlowerBed, which I've begun to depend upon when working in SL QC 4.

Quartz Composer Stuff. George's. Quartz Composer. Best Quartz Composer Tutorials. Best Quartz Composer Tutorials Quartz Composer is a powerful tool for processing and rendering graphical data.
You can use it easily for manipulating any type of graphics in real time. It uses node based visual programming language and can be easily adopted by non-programmer due to it simplicity. It uses OpenGL, OpenCL in new Mac OS X, Core Image, Core Video, JavaScript, and other technologies. You can drag and drop, link nodes and play with values to create amazing graphics.

Screen Saver Tutorial shows how to create your own screensavers using Quartz Composer. Quartz Composer. Patches[edit] Quartz programming through Quartz Composer works by implementing and connecting patches.[4] 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 lazy evaluation 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; MIDI and audio; keyboard; or other movements. A collection of patches can be melded into one, called a macro. To control the order of rendering, each renderer is assigned a layer, indicated in its upper-right corner. Some patches can have subpatches, which allows for global parameter changes to just the included subpatches. With Version 3.0, it became possible to turn compositions into Virtual Patches.
