A LabelEffect is an Effect that labels on the Object within an ObjectSet.

Example

Labelling an ObjectSet

In this example we create four Object, then add two of them to an ObjectSet.
Then we apply a LabelEffect to the ObjectSet, causing it's Object to become labeled, while the other two Object remain without labels.

// Create a Viewer
var viewer = new BIMSURFER.Viewer({ element: "myDiv" });

// Create a Camera
var camera = new BIMSURFER.Camera(viewer, {
       eye: [30, 20, -30]
   });

// Spin the camera
viewer.on("tick", function () {
       camera.rotateEyeY(0.2);
   });

// Create a CameraControl so we can move the Camera
var cameraControl = new BIMSURFER.CameraControl(viewer, {
       camera: camera
   });

// Create an AmbientLight
var ambientLight = new BIMSURFER.AmbientLight(viewer, {
       color: [0.7, 0.7, 0.7]
   });

// Create a DirLight
var dirLight1 = new BIMSURFER.DirLight(viewer, {
       color: [0.6, 0.9, 0.9],
       dir: [1.0, 0.0, 0.0],
       space: "view"
   });

// Create a DirLight
var dirLight2 = new BIMSURFER.DirLight(viewer, {
       color: [0.6, 0.9, 0.9],
       dir: [-0.5, 0.0, -1.0],
       space: "view"
   });

// Create a BoxGeometry
var geometry = new BIMSURFER.BoxGeometry(viewer, {
       id: "myGeometry"
   });

// Create some Objects
// Share the BoxGeometry among them

var object1 = new BIMSURFER.Object(viewer, {
       type: "IfcRoof",
       geometries: [ geometry ],
       matrix: BIMSURFER.math.translationMat4v([-8, 0, -8])
   });

var object2 = new BIMSURFER.Object(viewer, {
       type: "IfcDistributionFlowElement",
       geometries: [ geometry ],
       matrix: BIMSURFER.math.translationMat4v([8, 0, -8])
   });

var object3 = new BIMSURFER.Object(viewer, {
       type: "IfcRailing",
       geometries: [ geometry ],
       matrix: BIMSURFER.math.translationMat4v([-8, 0, 8])
   });

var object4 = new BIMSURFER.Object(viewer, {
       type: "IfcRoof",
       geometries: [ geometry ],
       matrix: BIMSURFER.math.translationMat4v([8, 0, 8])
   });

// Create an ObjectSet that initially contains one of our Objects

var objectSet = new BIMSURFER.ObjectSet(viewer, {
       objects: [object1 ]
   });

// Apply a Labels effect to the ObjectSet, which causes the
// Object in the ObjectSet to become labelsed.

var labels = new BIMSURFER.LabelEffect(viewer, {
       objectSet: objectSet
   });

// Add a second Object to the ObjectSet, causing the Labels to now render
// that Object as labelsed also

objectSet.addObjects([object3]);
