Been playing with the different rotation functions on an Object3D and it’s not working. Hopefully there is a quick solution for my question. I basically have a Sphere here, although it could be any other geometry, and I have in this example, a DirectionalLightHelper that is positioned initially at the top of the Sphere. The Helper is targeting a random Object3D. If the Sphere translates, I can maintain the Helper to the top of the Sphere.
It is when the Sphere starts to rotate on all 3 axis that things gets complicated.
Is there a function to use that can match the Helper’s location to that of the original top of the Sphere?
