[pstricks] 3d-intersections

hi list,

I want to draw a picture like this:

a pyramid with base area in xy-plane (given via 3D-coordinates of edges)


the intersections of this pyramid with a set E_i of planes parallel to  
the xy-plane, for example E_0=xy-plane, E_1=plane intersecting z-axis  
at z=1 etc.

is this possible?

further: given any closed/finite 3D-object, are there possibilities to  
visualise sets of intersections like above?
