ofxTweenzor is a addon for OpenFrameworks that allows for tweening values over time. I began developing the addon because I started using OF on the iPhone and I wanted a little transition here and there. I started programming and someone mentioned ofxTween. I checked it out and turns out that it runs on poco events and right now poco is not included in the iPhone build. Being a Flash developer, I wanted some tweens and I wanted to get familiar with events in C++ and how they could be handled, which took a little getting used to. I learned a great deal about pointers and events in C++, and I still have a way to go.
Hopefully someone will find this useful, and any questions or comments are welcome.
The easing equations are from both Robert Penner and the Tweener class by Zeh Fernando, Nate Chatellier and Arthur Debert.
The source includes a basic example file, and most of the following is included in there.
