Ok, here comes the "pain in the neck" part
:
In PS just make 3D->New shape from layer->Sphere. Remove the Deffuse texture, choose the color for it. Create Opacity texture, open it, add a Black Solid color layer, create new layer, convert it to Smart Object. Open this Smart Object, go to Image->Image Size and change it's width to 3 times of the original. Draw some white diagonal line on it. Save.
Now go back to Opacity texture document, select the Smart Object layer and press Ctrl-T. Move the layer horizontally so that only the leftmost third part is visible. Duplicate the Smart Object layer, press Ctrl-T. Move the layer horizontally so that the middle part is visible(add a 200% vertical Guide to help). Duplicate the Smart Object layer, press Ctrl-T. Move the layer horizontally so that the third part is visible. Save and take a look at what you've got in the main image.
Not that much of a "pain", huh?
Tweak the Sphere Material texture params like Gloss and Shine, set Lights, etc.
