Currently use QC to make custom layers for Bonix TV - a vision mixing kind of application for OS X with a kind of QC stack of layers, each layer being a composition with published ports and some protocols for data types. Also generate sports graphics and twitter feeds and so on for video score boards at large sporting venues.
Spent a few years learning Quartz Composer as my way back into coding from a decade away doing design related work. Film, graphics, studied Architecture for a few years and got involved in publishing then film. Now moving into front side web development. Hope to get into app dev with Vuo and rapid app prototyping.
I think Vuo would benefit tremendously for ease of use by new users in making these types explicit and even changing the wire thickness/dashes or port shapes to make this more explicit.
Images are bit format. Scenes, shape objects and layers have their unique structural definitions. It’s not clear to the new user how to proceed a lot of the time given the large number of processing nodes that are specific to one or another data type. It’s a catch 22, until you learn about all of them your end up chasing your tail a lot in Vuo in my experience.
