 		*Raycaster* delegates to the [page:Object3D.raycast raycast] method of the passed object, when evaluating whether the ray intersects the object or not. This allows [page:Mesh meshes] to respond differently to ray casting than [page:Line lines] and [page:Points pointclouds].

-		*Note* that for meshes, faces must be pointed towards the origin of the [page:.ray ray] in order to be detected; intersections of the ray passing through the back of a face will not be detected. To raycast against both faces of an object, you'll want to set the [page:Mesh.material material]'s [page:Material.side side] property to *THREE.DoubleSide*.
