  • openFrameworks iPhone 3GS / OS 3.0

    i’ve been dealing with a performance bug in a particle + accelerometer oF app. the same project which has run very smoothly on a first generation iPhone with OS 2.2.1 has a noticeable stutter on an iPhone 3GS with OS 3.0. there was no improvement despite several rounds of optimizing the openGL drawing code and […]

  • …little help (oh, malloc)?

    i’m having a time of it tracking down a resource allocation bloat culprit in an iPhone app i’m working on. i’ve narrowed it down to when i’m rapidly updating the center property of a UIImageView. a snippet from the Instruments application is below: there are hundreds (if not thousands) of these messages, and the object […]

  • (overly simplistic) saving state in oF for iPhone

    There was a recent comment about saving / restoring application state when using openFrameworks for iPhone which got me to thinking about how to do it. Apple’s frameworks provide a fairly thorough way to save state to the disk and restore later. There seem to be three primary ways to do this: simple plist files […]

  • openFrameworks knitting circle

    Had a really nice time tonight at the oF knitting circle held at Parsons in NYC. Saw several really inspiring projects and spoke to several people about using openFrameworks for iPhone development and showed the current version of the particle game using ofxiPhoneAlertView. Quite a few folks mentioned that they have become interested in openFrameworks […]

  • ofxiPhoneAlertView

    Here is a (really) basic wrapper for the UIAlertView in openFrameworks of iPhone. Not all of the necessary delegate methods have been implemented yet, but this is enough for me to get the proof of concept rolling in an app I’m building. Feel free to let me know how I can do things better, or […]

  • BarCampNYC4 presentation

    BarCampNYC4 was hosted by ITP on May 30-31st. It was a great event – I’d highly recommend going to another one. I did a presentation titled “Using openFrameworks for iPhone App Development” which I think went well, although it was quite dense. Can’t be helped, I suppose. The walk-through of getting set up with openFrameworks […]

  • Using openFrameworks for iPhone dev

    [Also available at ITPedia. Watch video of the BarCampNYC4 presentation.] This is an overview of getting set up using openFrameworks for iPhone development. What is openFrameworks? openFrameworks is a “a C++ library for creative coding”. It shares a similar philosophy with Processing (as a library for Java). The intended audience “are folks using computers for creative, artistic […]

  • [my] summer of code

    In preparation for several iPhone application development gigs which have lined up for the summer I’m getting back into my previous projects. Specifically, I’m going to get Follower and Pinwheel ready for release and am looking to push them out to the AppStore in the next month or so. Also, as an exercise to get […]

  • 1-2-10: Cloud Reader interface comps

    The first web interface wireframes for Cloud Reader. Overall comments: too busy, too complicated for what is supposed to be a simple service. Good advice, back to the sketching.

  • openFrameworks + iPhone libs

    I’ve had a few days to test the libraries I cobbled together for using openFrameworks with iPhone and also received positive reports from some folks who tried out the Makefiles I provided to them, so here they are for anyone who’s willing to try them out. -please make these instructions better if you see fit-
