Answer 1

You have to keep pushing the points continuosly though no touch event is sent.

A way is start an interval on touchstart event that push last point every x milliseconds. Es:

function starTimer(){
window.setInterval(function(){
genrate();
}, 200);
}

window.addEventListener("touchstart", function(event){
starTimer()
});

Its a very simple code that dont handle touch ending, but is simple to understand

Answer 2
