Yup, indeed.
Types that are to be stored in Fields need to have corresponding
TypeTraits, and the implementation of those methods. The main reason is
support for converting from/to binary and strings, for clustering and
file IO. You can take a look at
Examples/NewTypes/OSGNewFieldType.{h,cpp} if you only need that type in
an application, or OSGNewFieldTypeLib.{h,cpp} if you need it in a dll.
If you only need that data in an application running on a single
machine, you could just use a void pointer (VoidP) Field and store your
pointer in there.
Hope it helps
Dirk
