Correct default orientation/rotation for mesh?

Questions
1

The lookAt function rotates the object to directions I dont want to.

I tried changing mesh.up vector values but couldn’t get it right.

I have sphere with arrow in it, which direction should I make the arrow point initially when creating the mesh?

The box aligned along z-axis.

So its always z-axis which is pointing towards lookAt vector?

Is it possible to point Y towards it instead of Z?

Nice example btw

You need to rotate geometry first
object.geometry.rotateY(Math.PI / 2);
object.geometry.rotateZ(Math.PI / 2);
