[pstricks] barycenter3d in pst-solides3d Doesn't work

[José Jesús Rosell Escolar]

Dear Herbert, 
My name is Jose Jesus and I am working in some geometric draws in 3D. 
I use pst-solides3d for that, but, when I try to get a barycenter of a system, using:

\begin{pspicture}[viewpoint=20 25 15](-3,-4)(3,4)
	\psset{solidmemory}
	\axesIIID(3,3,3)
	\psSolid[object=point,name=M, args=1 1 1]
	\psSolid[object=point,name=P, args=1 6 1]
%	\psSolid[object=point,name=Q, args=1 3 4]
	\psSolid[object=point,definition=barycentre3d,args={[M 4 P 3]},linecolor=red]
\end{pspicture}


It draws nothing.

What am I doing wrong???

Thank you.
