How can I add a click event on pushpins to autodesk forge? In an existing extension , he opens the content for pushpin using the camera focus on it. I want to open it with click on pushpin.
But I add the pushpini to the model manually and translate the coordinates with the following code
var setData = function (event) {
var screenPoint = {
x: event.clientX,
y: event.clientY
};
if (screenPoint) {
var n = normalize(screenPoint);
var dbId = /*_viewer.utilities.getHitPoint*/ getHitDbId(n.x, n.y);
if (dbId == null) return;
}
}
function getHitDbId(x, y) {
y = 1.0 - y;
x = x * 2.0 - 1.0;
y = y * 2.0 - 1.0;
var vpVec = new THREE.Vector3(x, y, 1);
var result = viewer.impl.hitTestViewport(vpVec, false);
console.log(result);
if (result) {
dummyData.push({
icon: Math.round(Math.random() * 3),
x: result.point.x,
y: result.point.y,
z: result.point.z,
});
window.dispatchEvent(new CustomEvent('newData', {
'detail': dummyData
}))
} else {
return
}
return result ? result.dbId : null;
};
function normalize(screenPoint) {
var viewport = viewer.navigation.getScreenViewport();
var n = {
x: (screenPoint.x - viewport.left) / viewport.width,
y: (screenPoint.y - viewport.top) / viewport.height
};
return n;
}
Is this even possible?
This has already been taken care of in the original plugin - simply append your own handler in the click callbacks below where hit test on the markups is performed:
this.onMouseMove = function(event) {
if(this.line3d){
this.update_DivLabel('onMarkupMove');
this.updateHitTest(event);
}
}
this.onClick = function(event) {
this.updateHitTest(event);
if (!this.hovered) return;
this.selected = this.hovered; //
//your own callback goes here
}
And adjust here to fine tune hit test accuracy:
function markup3d(viewer, options) {
this.raycaster.params.PointCloud.threshold = 5; // hit-test markup size. Change this if markup 'hover' doesn't work
this.size = 150.0; // markup size. Change this if markup size is too big or small
The original live sample handles click as well by displaying a hoevering label:
