If I'm creating new renderer using the following code (taken from http://openlayers.org/en/master/examples/geolocation-orientation.html) ,
map.beforeRender(function (map, frameState) { if (frameState !== null) { // use sampling period to get a smooth transition var m = frameState.time - deltaMean * 1.5; m = Math.max(m, previousM); previousM = m; // interpolate position along positions LineString var c = positions.getCoordinateAtM(m, true); var view = frameState.viewState; if (c) { view.center = getCenterWithHeading(c, -c[2], view.resolution); view.rotation = -c[2]; marker.setPosition(c); } } return true; // Force animation to continue });How can I disable / delete it when I want to stop this rendering ?
