Hello,
So I thought of playing with OF and browser and I wrote a sample example with ofPolyline drawing.
Adds vertices in mousedrag and renders the polyline in draw().
//--------------------------------------------------------------
void ofApp::draw(){
ofSetColor(ofColor::white);
line.draw();
}
//--------------------------------------------------------------
void ofApp::mouseDragged(int x, int y, int button){
line.addVertex(x, y, 0.0);
}
The sample starts fine in browser but after a couple of line strokes, I see the below error in JS console.
[GroupMarkerNotSet(crbug.com/242999)!:D0E6B75DEF7F0000]GL ERROR :GL_INVALID_OPERATION : glDrawArrays: attempt to access out of range vertices in attribute 3
Not sure if this is a bug.
By the way the test app runs fine without any issues on native OSX.
Many thanks
Gracias
