How to convert coordinate in threebox.scene to threebox.world or longitude /latitude?

[huangzhe2015]

Hello

I am using Raycaster to locate the intersect point when I click a 3D model on map with threebox.
var intersects = raycaster.intersectObjects(tb.scene.children, true);
Then I get the intersects[0].point which seems the coordinate in threebox.scene space.
I am wondering how can I convert intersects[0].point to some coordinate in threebox.world space or longitude /latitude?

Thanks.

Hello @huangzhe2015

Were you able to find a solution to your problem?

I am kind of trying to achieve the same thing.

If you were able to find a solution, it would be wonderful if you can reply to this comment

Thank you so much

Hello @harriputterr
I am still working on this issue.
I have tried to calculate below way but it failed.

1. Get the center of map by map.getCenter() which is lng and lat format.
2. Convert center to world position by projectToWorld(), that is a Vector3
3. Use Vector3.add() method to add the position in scene system. Also I consider how many meters are equal to a pixel, according to https://docs.mapbox.com/help/glossary/zoom-level/#zoom-levels-and-geographical-distance.
   But I can't get correct result.

1. get the coordinate of center on map:
   var coordMapCenter = map.getCenter();
   var coordMapCenterArray = [coordMapCenter.lng, coordMapCenter.lat, 0];

2. place the object to the center:
   obj.setCoords( coordMapCenterArray );

3. move the object to intersect point by below code.
   obj.translateX(intersectPoint.x/tb.world.matrixWorld.elements[0]);
   obj.translateY(intersectPoint.y/tb.world.matrixWorld.elements[5]);
   obj.translateZ(intersectPoint.z/tb.world.matrixWorld.elements[10]);

That is how I find to convert coordinate in threebox.scene to threebox.world by chance.
