GEA

GEA (Graphics Engine for Artists) is an Heterogeneous System for Live Visuals with the use Dynamic Algorithmic Score. The main parts are the following:

• openFrameworks (http://www.openframeworks.cc/download/)
• ofxLua by Dan Wilxon (https://github.com/danomatika/ofxLua)
• SuperCollider (http://supercollider.sourceforge.net/)
• Emacs (http://www.gnu.org/software/emacs/)

Installation ans System Requirements

• Mac OSX 10.10.1
• openFrameworks latest version 0.8.4 from http://www.openframeworks.cc/download/
• ofxLua: https://github.com/danomatika/ofxLua
• ofxMIDI: https://github.com/danomatika/ofxMidi
• XCode Version 6.1.1. (usefull tool for XCode plug-in https://vimeo.com/79061998)
• Fix bug from mypost at OF forum [fn:offorumpost]. If flickering is a problem, there is a change you can make deep inside OF:
  1. open ofAppGlutWindow.cpp from ./libs/openFrameworks/app
  2. search replace GLUT_DOUBLE with GLUT_SINGLE
  3. search replace glutSwapBuffers with glFlush. This will help with ofSetBackgroundAuto(false), but it will make ofSetBackgroundAuto(true) look bad.
• Add ofxLua from https://github.com/igoumeninja/ofxLua/tree/gea_150214 forked from https://github.com/igoumeninja/ofxLua
• Switch to latest gea version branch
• SuperCollider 3.6.2 and algorothmic-dynamic-score (https://github.com/igoumeninja/algorithmic-dynamic-score)
• Install homebrew and Boost C++ libraries
• Install Emacs and osc.el package (http://delysid.org/emacs/osc.html)
• Δημιουργία functions at Emacs for sendind OSC messages
