How can I create a spherical perspective grid (six point perspective) in Photoshop or Illustrator CS5 where the poles are shown on the top and the bottom (exactly like the image below).
I have explored the 'polar grid tool' in Illustrator and the 'Vanishing Point' filter in Photoshop. Neither of these tools are able to create this kind of perspective grid.
If possible I would like to find a method that allows customizations like, setting the number of concentric and radial dividers like how the 'polar grid tool' works, rather than trying to build it with shapes or something..
Thanks for any help
EDIT: I have learned that this is referred to as Six Point Perspective.
EDIT: reference image source, in case its at all useful
