Overview Intros from me, and you OF history and inspiration OF structure and syntax Running and modifying the examples Using addons and contributed code Getting started on a project you want to make
Intros Me − http://kylemcdonald.net/ − https://twitter.com/#!/kcimc You − Name − Experience level − What you want to make with OF
A (Rough) History of OF− Pre-2003: ACU library at MIT Inspired Processing via Ben Fry and Casey Reas Golan Levin also studies at MIT, uses ACU to teach− Zach Lieberman studies under Golan Zach cant teach ACU, develops OF− Theo Watson studies under Zach (2004+) Theo does OSX, Zach does Windows− Arturo Castro meets Zach + Theo (2007/8?) Arturo ports to Linux, joins the OF core team− OF lab (Ars Electronica 2008)− OF dev conferences (2011 Pittsburgh, 2012 Detroit)
OF Inspiration Lets check out some awesome OF work! openFrameworks on Vimeo openFrameworks on Flickr openFrameworks on Creative Applications
OF Structure OF is a bunch of classes and functions that simplify things by reducing the amount of code you have to write The “core” of OF is in libs/openFrameworks/ A good way to see everything in one place is the OF reference Some more notes on folder structure
OF Syntax Its just C++ syntax, except for the “of” prefixes and some other minor conventions Some great resources for learning C++ at the bottom of the about page So...
C++ Syntax <> are for templates, called “generics” in java . (dot operator) is for accessing children of objects, :: (colon colon) is for classes and namespace access You dont normally use an “int arr;” like in Processing, you have to use a “vector<int> arr;” Operator overloading means you can use complex types with mathematical notation: for example, ofVec2f
Comparison to other Environments Cinder has a steeper learning curve, but was created by “real” programmers Pocode is more like Flash in having a scene graph, where everything is drawn implicitly Processing is most similar, but the community is more focused on sketches than addons.
Running and Modifying Examples 007 and before, everything is in apps/examples/ and apps/addonsExamples 0071 and after, everything is in examples/ There are a lot more examples online, were continually working to bring in more.

Getting Started on a Project / Hacking Together What project do you want to make? Lets brainstorm about what you need to make it happen. What techniques do you want to play with? Lets see if theres something out there that you can wrap or use.
