plot3d - discrete



Hello list,

using the command

--> plot3d(x**2-y**2, [x,-5,5], [y,-5,5], 		
[plot_format,openmath])$

there opens "Shelter's 3d Plot Window", where it is possible 
to rotate the displayed graph.

is it possible to do similar with a list of points?

for example: 
I want to define the edges of a tetrahedron:

--> pA: [1,1,1];  pB:[-1,-1,1]; pC:[-1,1,-1]; pD:[1,-1,-1]

then a List

--> L_tetra:float([pA,pB,pC,pA,pD,pC,pD,PB])

and genarate in "Shelter's 3d Plot Window" ( or similar)  its 
picture with

--> plot3d([discrete,float(L_tetra)],[plot_format,openmath])

but this option doesn't exist.

Is ther an other way?
