Although it seems trivial, it fails to achieve the 3D effect placement of dots on the globe theme, see http://pasteboard.co/2Xy9WGE8T.jpg.
Standard way somehow I cannot reach (spherize, distorsion, etc.) Does it works with some plugin or way to accomplish this?
thanks for any advice
Peter

I'd personally map it out on a 3D object,  but you're not going to  do  that in Photoshop. A blend in Illustrator would likely give you good result as well. I'm opening PS right now and trying a few things.  If I come up  with something workable I'll post back.

Actually I'm  getting a pretty good approximation using distort/spherize, but I'm  using a grid of dots not a single row.

well, try to show me then, what did you achieve. A small problem is that I need to gain real 3d look in 2D space. It means the position of those dots on the globe, as well as to the real object on sphere. And I don't want to do it manually, like this one in Illustrator. Most of it is visible above and below, at the poles. I was looking for a plug-in for Photoshop, something better as spherize, see below.

I know that the best course of action for this case is it to make a ball in some 3d editor and place this motive on it as a texture. Then it would be physically accurate. Photoshop for 3d stuff I don't use at all, for my needs I have still CS5.

thx a lot

Peter

Make a grid of dots, say  7x7.  If you use a single column it will  distort and won't be accurate,  but a grid will  warp  evenly as long as it is centered(you'll have to  delete 4 on the outside)...

...and yes, your best bet would be to  map  it to  3D object as a texture. Anim8or is free and would be super easy  to  use with  UVMapper to knock this out correctly and fast.

Use the Ellipse Shape tool to make the first circle near the middle of your canvas.  Hold down the Shift key to force the round circle. Set the fill to your color and stroke to none.

Copy the ellipse shape layer.
Use Free Transform and Shift > Right Arrow to move it, and set width (W:) and height (H:) both to 90%.
Now Shift Ctrl Alt t (Shift Cmd Opt t) as many times as you need to copy the ever smaller circles. (not that with Shape layers, Step & Repeat adds to the same layer)
Merge the two shape layers, and copy the resulting merged layer.
Use Free Transform and choose Flip Horizontally, but Alt (Opt) click to the left of the merged shapes to place the center handle to the left of the shapes so that they flip about this point.
Fine tune the space between the shape layers and merge them Ctrl e (Cmd e), and move them to the middle of the canvas.  Note mine were a bit too large and I have downsized them a touch to fit.
Free Transform, and chose Warp from the Options bar (red highlight) and Arc from the Warp Drop down on the left of the Options bar

I don't remember exactly but you can find it in Blending Options

"dots on a sphere" in Illustrator

Row and columns of circles can be drawn to arbitrarily 10 x 10 array and aligned vertically and horizontally.

The array can be made into a symbol on the symbols pallet.

 

To make a sphere, draw a circle and cut it on the top and bottom nodes.

Take the right hand arc and apply "revolve" under the 3D menu (under the effects menu)

this will create a sphere.

To apply the dots, click on preview and the "Map Art"

Map art will bring up the symbols pallet from which you can select your dots..

You also can make the sphere transparent so only the dots are visible.

There is  much twerking and adjusting to get this look remotely correct.

Because of edge distortion, the more dots in your array, the better.

 

You can apply lighting effects and some perspective to get better results in the "revolve" menu

So this makes scalable vector dots with a transparent background.

Edge distortion is the one abiding flaw.

(See below)

Maybe use Text and type ... then turn that ... text into a 3d layer?
