A HighlightEffect is an Effect that highlights the Object within an ObjectSet.

Example

Highlighting an ObjectSet

In this example we create four Object, then add two of them to an ObjectSet.
Then we apply a HighlightEffect to the ObjectSet, causing it's Object to become highlighted while the other two Object remain un-highlighted.

// 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 Highlight effect to the ObjectSet, which causes the
// Object in the ObjectSet to become highlighted.

var highlight = new BIMSURFER.HighlightEffect(viewer, {
       objectSet: objectSet
   });

// Add a second Object to the ObjectSet, causing the Highlight to now render
// that Object as highlighted also

objectSet.addObjects([object3]);
