now that release 9 has support for 3rd party visualizers it is time to teach the interested how to craft them.
NBB visualizers are nothing more that a quartz composition. you will need apples free Quartz Composer application found on you leopard install DVD.
As of version 1.1 NBB now uses apples iTunes visualizer protocol. when creating a new document in quartz composer choose the "music visualizer" option and work from there; its as simple as that.
If you are new to Quartz Composer i suggest downloading "iVisualize" and making a simple port or two of those visualizers. If you create any visualizers and want me to bundle them I sure can do that, but I only want to include real visualizers in the application, nothing that is "faked".
Apples itunes visualizers are located in /system/library/compositions/
you may install them in the music module and use them with NBB. note that they don't seem to work exactly as they do in itunes. I suspect apple has a different idea of what "spectrum" and "peak" are... but most of them work well enough. jelly is pretty cool
you may install your visualizers in:
I am working on a "quick install" method for visualizers similar to the install method for modules themselves. will likely use drag and drop from finder.
