raycast and linecast

Unity3D has a way of doing a query to find all object that are blocking (occluding) a line or a ray between two points. http://docs.unity3d.com/ScriptReference/Physics.Raycast.html

Is there a similar function in CesiumJS? I need to find object that are block the view between a simulated LIDAR and the objects in the scene and return the value of those objects.

Sorry, I don’t think this functionality currently exists in Cesium.
