HI,
I am trying to display the streamed data that I get from an array so that I see the line moving as the data change.
here is the code I am using. But the visual result I get is a bit odd. I don't understand where is the mistake.
Anyone any help please?ofBeginShape(); ofNoFill(); ofSetLineWidth(linewidth); ofSetColor(color); float k = TWO_PI/wl; //wl is the wavelength if (videoTracker.getFound()) { for (int x=0; x<ofGetFrameNum()%ofGetWidth()/3; x++) { ofCurveVertex(xpos + x, ypos + sin(k*(x) - ofDegToRad(dataPointer[index%arraySize])) * amplitude ); } } ofEndShape();
