Hi Denis,

thanks for your feedback.

Take a look at the various pfvMousePicker samples inside
%PFROOT%\Src\pguide\libpfv\picker.

There's a bunch of simple examples with gradually more
complex use of the pfvPicker (and derived classes) API.

You should actually not call the pick method directly, but
call picker->update instead (once per frame). Picking is done
within the update method, even though this doesn't seem to be
documented in our manpage.

Let me know if you need further assistance.

Regards,
Paolo
