“Trying to learn Apple’s free visual patching tool Quartz Composer, useful for making your own filters and simple generative effects? Or perhaps you’re learning VDMX, the brilliant, semi-modular Mac-friendly visual tool – which also happens to host Quartz Composer compositions as effects or generative sources? Well, good news for you: readers have a ton of tutorials for both.
Possibly the most perplexing concept to wrap your head around in Quartz Composer is the iterator. Iteration in code is pretty straightforward (think “for” loops), but while it’s powerful in a patch, it’s conceptually a bit of a challenge. ”
VDMX is one of my favorite programs for controlling projections — well worth checking out if you’re into augmented reality-type things.
