| itk::Mesh objects may be written and read to and from a variety of file formats. In this example, a spherical mesh is created, written to file, and read back in in a format specified by the user. | | {{warning|1=The media wiki content on this page is no longer maintained. The examples presented on the https://itk.org/Wiki/* pages likely require ITK version 4.13 or earlier releases. In many cases, the examples on this page no longer conform to the best practices for modern ITK versions. |
