Rotate Point around Point
function rotatePoint(point, center, angle){

var rotatedX = Math.cos(angle) * (point.x - center.x) - Math.sin(angle) * (point.y-center.y) + center.x;
var rotatedY = Math.sin(angle) * (point.x - center.x) + Math.cos(angle) * (point.y - center.y) + center.y;
return new THREE.Vector2(rotatedX,rotatedY);
