Unable to intersect Points - three.js

Question

I unable to intersect Three.Points but i am able to intersect THREE.Mesh, below is my code: Can someone please help me to understand what mistake i am making. When i intersect the Points all i get is 0.
function init()
{
geometry = new THREE.Geometry();
vertex = new THREE.Vector3();
vertex.x=( [i + 3 ] * 140 ) - 1330;
vertex.y = - ( [i + 3 ] * 180 ) + 990;
vertex.z = 100;
geometry.vertices.push(vertex);
var particleTexture = THREE.ImageUtils.loadTexture(imgstr);
var materials = new THREE.PointsMaterial({
map:particleTexture,
size: 150
});
particles = new THREE.Points(geometry, materials);
scene.add(particles);
targetList.push(particles);
}
function onDocumentMouseMove( event ) {
event.preventDefault();
mouse.x = ( event.clientX / window.innerWidth ) * 2 - 1;
mouse.y = - ( event.clientY / window.innerHeight ) * 2 + 1;
}
function onDocumentMouseDown(event){
var projector = new THREE.Projector();
var vector = new THREE.Vector3(
(event.clientX / window.innerWidth) * 2 - 1,
-(event.clientY / window.innerHeight) * 2 + 1,
0.5);
projector.unprojectVector(vector, camera);
var raycaster = new THREE.Raycaster(camera.position,vector.sub(camera.position).normalize());
var intersects = raycaster.intersectObjects(targetList);
console.log(intersects.length);
}

Answer 1

function onDocumentMouseDown( event ) {
event.preventDefault();
if(event.which == 1) {
var raycaster = new THREE.Raycaster();
raycaster.setFromCamera( mouse, camera );
raycaster.params.Points.threshold = 100000; // bigger number = bigger sensitivity
var intersects = raycaster.intersectObjects( myobjectsarray,false); // myobject array is array of THREE.Points object
if ( intersects.length > 0 ) {console.log('tadaah',intersects);}
}
}
