1 shape coloured with one dual coloured texture! So that's how your spheres were so round. I was wondering where your sizing pixels were. I'll have to remember that trick.
My suggestion has 1 dot per sphere pasted into X3D. Extruded to 180, bevel 'curve' to deph 999, in 'rotate1'.
Here are 4 dots to make 4 globes (a bit rounder this time)
