Solution:
To resolve this issue, ensure you have the most recent version of DomEvents from this repository, which has been updated to r74.
Explaination:
Understanding what's happening may take some time:
The use of THREEx.DomEvents involves internal utilization of THREE.Raycaster to detect mouse interactions with meshes. A recent change in ThreeJS no longer allows the raycaster to intersect with invisible meshes (check source here). However, if your click event still triggers, why worry?
Let's delve into Linkify:
THREEx.Linkify = function(domEvents, mesh, url, withBoundingBox){
withBoundingBox = withBoundingBox !== undefined ? withBoundingBox : true
// create the boundingBox if needed
if( withBoundingBox ){
var boundingBox = new THREE.Mesh(new THREE.CubeGeometry(1,1,1), new THREE.MeshBasicMaterial({
wireframe : true
}))
boundingBox.visible = false
boundingBox.scale.copy(size)
mesh.add(boundingBox)
}
// ...
If the fourth parameter withBoundingBox evaluates to true when not supplied, Linkify generates an invisible "bounding box mesh" that encompasses the targeted mesh. Consequently, the raycaster fails to trigger an intersection. To enable the raycaster to detect intersections even though the boundingBox is hidden, only set the visibility of the mesh's material to false, not the entire mesh:
