Arts Programming Frameworks 

openFrameworks Cinder processing.py di!culty of framework community support Processing 

openFrameworks Cinder processing.py di!culty of framework community support Processing Best place to start. Everything packaged together. Still very powerful! 

openFrameworks Cinder processing.py di!culty of framework community support Processing Big jump in language. Stable platform with strong community. For when the power of C++ is needed. 

openFrameworks Cinder processing.py di!culty of framework community support Processing Definitely need to be a confident coder. Fewer compromises than oF as it doesn’t try be fully cross-platform. Targeted at Mac OSes. 

openFrameworks Cinder processing.py di!culty of framework community support Processing New kid on the block. Not really a community or a lot of support yet. Python is incredibly friendly to those just starting out. 

How are these platforms similar? 

Native window handling 

Native graphics and image handling 

Simple and direct access to mouse and keyboard input 

void setup() void draw() 

void setup() void draw() Do things that happen only once, when the program begins. 

Do things that happen repeatedly, at the frame rate of the program. void setup() void draw()

Wrap-Up 

There are di"erences in the platforms and libraries! Full screen Color modes Background refreshing ... 

Processing All the frustrations that come with Java Really stable, supportive community Works out of the box, with no nonsense IDE IDE becomes quickly limiting, but can move to Eclipse From an educational standpoint can be inhibiting as hides away a lot of programming concepts (that every Processing instance is an extension of a base class PApplet) 

openFrameworks All the power and problems of C++ http://wiki.openframeworks.cc/index.php?title=OF_for_Processing_users Really stable, supportive community Have to deal with an IDE like XCode Nothing is binary means long compile times and that correct file structure is essential Pet peeve is calling everything testApp.cpp and testApp.h - descriptive class and file names are your friend! 

Cinder Again, all the power and problems of C++ C++ in your face Much smaller community Less thorough documentation Great for Mac 

processing.py Python <3 Basically no community No all-in-one IDE But it’s Python! 

Arts programming platforms ...vary in noob-appeal. ...have similar functionality. ...intended for (cross-platform) interactive applications. Lots of options and resources available.
