An approach to implement the spacemouse to Delphi.

{
  Written by TutTut

  This is an approach to implement the
  3d-Spacemouse to Delphi

  i am not a so well programmer
  therefore it doesn't work really because
  there were different problems to me


  i don't know where the SpaceMause
  unit comes from, i have some samples
  from c and that dcu, that dcu
  should be the implementation from the
  magelln-source

  maybe some will find interest
  and have a further look on such
