How to convert coordinate in threebox.scene to threebox.world or longitude /latitude? #422

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 @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.
