ofxQuartzComposition and ofxCocoa for openFrameworks (2010)
Two new addons for openFrameworks. Actually one is an update, and major refactor, so much so that I’ve changed its name: ofxCocoa (was ofxMacOSX) is a glut-replacement addon for openframeworks to allow native integration with opengl and cocoa windowing system, removing dependency on glut. Has a bunch of features to control window and opengl view creation, either programatically or via InterfaceBuilder. http://github.com/memo/msalibs/tree/master/ofxCocoa/
Currently there is support for:
- loading multiple QTZ files inside an openframeworks application.
- rendering to screen (use FBO to render offscreen)
- passing input parameters (float, int, string, bool etc) to the QTZ input ports
- reading ports (input and output) from the QTZ (float, int, string, bool etc)
- passing Images as ofTextures to and from the composition (you currently can pass images as QC Images, but you would have to manually convert that to ofTexture to interface with openFrameworks)
How is this different to Vades ofxQCPlugin (http://code.google.com/p/ofxqcplugin/) ?
ofxQuartzComposition is the opposite of ofxQCPlugin. ofxQCPlugin allows you to build your openframeworks application as a QCPlugin to run inside QC. ofxQuartzComposition allows you to run and control your Quartz Composition (.qtz) inside an openframeworks application.
In the video above there are two quartzcompositions being loaded and mixed with openframeworks graphics, in an openframeworks app. The slider on the bottom adjusts the width of the rectangle drawn by openframeworks (ofRect), the 6 sliders on the floating panel send their values directly to the composition while it’s running in openframeworks.
