I am a newbie to Blender, and would like to:

  1. Create a hollowed sphere with a thickness.
  2. Be able to slice it horizontally and vertically
  3. Be able to select each piece, modify it and animate it

In short, I'd like to compose/decompose a sphere using Blender editors, animate the slices to do so.


1 Answer 1

  1. ⬆ ShiftA, M, U Add UV Sphere.
  2. F9 Set resolution for slicing.
  3. ⭾ Tab, F3 Edge Split, ⭾ Tab.
  4. Add a new vertex group SHELL.

  1. Add Solidify Modifier, set Thickness to 0, Output Vertex Groups → Shell to SHELL; ✲ CtrlA Apply the modifier.
  2. ⭾ Tab, ⎇ AltA deselect.
  3. Select vertices from SHELL, then S scale them up or down a bit (depending on how much thickness you want to have).

  1. A select all [I moved the sphere to confirm/show all vertices are selected], ⬆ ShiftN Recalculate normals.
  2. P, L Separate by Loose Parts. ⭾ Tab.

You now have a sliced sphere. The slices can be animated independently using the I key:

Consider selecting all pieces and then F3 and search for "set origin…".

  • $\begingroup$ Thank you. It looks likes a very elaborated solution. I am on a MacBook Air without a mouse so I am kinda stuck with step 2, where you brought up the property list to change the segments and rings. $\endgroup$

  • $\begingroup$ The playback goes a bit fast. If there is a convenient way to slow it down, I'd appreciate it very much. I had wanted to get a complete horizontal and vertical slices, which would divide a sphere into a set of rings. Your solution seems to offer a finer granularity, which is very good too, as it will give me more flexibility down the line. As I work through your solution, I should be able to reconstruct the pieces you generated into a ring. At any rate, if you have a quick offhand solution to do so, I'd appreciate it very much too. Thanks for the time and helps. $\endgroup$

  • $\begingroup$ @AnhNguyen I don't use Apple products unfortunately, If you can't open the last operator settings with F9, you can look for a collapsed windows in the bottom-left corner and click it: i.imgur.com/nCtjWaA.png $\endgroup$ Commented May 23, 2023 at 8:46
  • $\begingroup$ @MarkusBroady I noticed that you don't use Apple. After playing around for awhile I was able to go pass step 1,2, &3. I am stuck at 4 as the new vertex group item field is not editable for me to enter the name. I did the followings to create the new vertex group <object data properties> <+>. Any clues? $\endgroup$

  • $\begingroup$ @AnhNguyen double-click the name to edit it. At least on Windows. $\endgroup$ Commented May 23, 2023 at 13:51
