I am sorry for replying late. And thank you very much for your comment,
Ron.
I think that the results was interesting. Because no number multiplied
by 0 comes to be 1. It would take a little time to explain my point.
Therefore I wrote it in our blog.
"Vector3D.w property for multiplication"

Any comments would be very appreciated.

You seem to be multiplying a null vector(zero length located at 0,0,0 at
the best interpretation) by a null or zero transformation. The results
will not be very interesting .
Perhaps you might try it with a not null vector and a not null
transformation and see if you get something more interesting.
Good luck,
