A new book by Bryan Chung, Multimedia Programming with Pure Data was recently published by Packt Publishing.
Despite it being a big part of Pure Data Extended, GEM – and making visuals in PD – doesn’t get as much attention as audio processing. Whereas sound-makers have resources such as Loadbang and excellent tutorials from Obiwannabe, visual artists have little access to such a comprehensive resource, which can be a bit off-putting for new users. With that in mind I was more than happy to be a reviewer for this book that focuses almost entirely on GEM and making visuals in PD.
Although it is definitely suited to new users this book does get quite complex in later chapters where it begins to detail camera tracking, OpenCV and particle generators. I even learnt a couple of things!
Most of the tutorials are written to work on all operating systems (Linux, Mac and Windows) though some instructions, such as installing libraries, aren’t always covered. That could be another book in itself!
