ofxMotioner

An addon to use MOTIONER which is open source intertial motion capture system easily in openFrameworks.

setup

/// setup ofxMotioner and setup OSC incoming port(argument0)
/// default incoming port is 10000(same as MOTIONER application)
ofxMotioner::setup(/*10000*/);

update

ofxMotioner::update();

debug drawing

draw all skeletons

ofxMotioner::debugDraw();

ofxMotioner::Skeleton

// this method is called the same number of all skeletons

ofxMotioner::Node

ofxMotioner::Node inherit from ofNode

ofxMotioner::NodeVec is typedef of std::vector<ofxMotioner::Node>

    	if (!n.getParent()) continue;
    	
	    // draw line
        ofSetColor(ofColor::green);
