Well i guess you’ll have to read this and make your own mesh

This kind of primitive has no built in support

  1. create a cylinder.
  2. clone it.
  3. scale it by 0.70f.
  4. Use Boolean.Subtract shape.
  5. taDa ready.



    Jme doesnt have boolean.subtract shape, but if you want you can implement that and contribute it.

    I may have a look at it after 1 month (after my exams).

Hi,tralala



Yes, there are at least two functions should be implement :

  • subtract shape.
  • cut one part of the shape.
