Hi folks
I am trying to get my openFrameworks window out of Syphon and in MadMapper. I can do it with the example code, no problem. I think the issue is that my code relies on the background not refreshing, creating a trailing circle. This does not display correctly. I do not know how to fix it or if it is even fixable/possible. I tried to load to a texture, but whatever I did, it failed.
what it should look like
type or paste code here
#include "ofApp.h"
//-----------------------------------------------------
void ofApp::setup(){
//General Code Setup
ofBackground(0);
ofSetFrameRate(60);
//SetBools
bC1 = false;
bC2 = false;
bC3 = false;
bAutoOn = false;
//SyphonStuff
mainOutputSyphonServer.setName("Screen Output");
mClient.setup();
mClient.set("","Simple Server");
}
//-----------------------------------------------------
void ofApp::update(){
}
//----------------------------------------------------
void ofApp::draw(){
//if I turn on the glClear, the pattern does not draw as
//it requires the background to not refresh.
// glClearColor(0.0, 0.0, 0.0, 0.0);
// glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
ofSetBackgroundAuto(false);
//draw the cirle pattern
pattern();
if(bAutoOn == true){
int b = ofRandom(4);
if (b==2){
autoPattern();
}

ofClear(0, 255);
