I created a surface mesh in itksnap with stl format. I can import it to blender. Please consider it with 3000 vertices and 1700 facets. At now I want to change the number of vertices to 2200. How can I do it?

  • $\begingroup$ You can use the Decimate Modifier, as described, but also X > Limited Dissolve, and/or W > Remove Doubles... with both these two solutions you can play with the parameters on the bottom of the left menu (activated with N) $\endgroup$

Reduce the number of vertices with the decimate modifier

  1. Add a decimate modifier to the object and set it to collapse.
  2. In the ratio field, enter desired amount / current amount.
  3. If needed, apply the modifier.
