[pstricks] pst-solides3d

[Herbert Voss]

Hi all,
pstricks-add definies the macro \psPie (see pp 8-9 of
http://www.ctan.org/tex-archive/graphics/pstricks/contrib/pstricks-add/pstricks-add-doc.pdf
I tried this also for three dimensional pies, but
pst-3dplot doesn't support hidden surfaces, which makes
it impossible to define a pie which can have single
outraged parts. A simple example is attached, which works
in fact of only two pieces. The macro is called as

\psPie[<options>]%
   {comma separated value list}% the data
   {comma separated value list}% outraged pieces
   {radius}

for the options see the documentation. However, I think
it must be possible to have a 3d solution with pst-solides3d
with \psPieIIID and the same syntax. Can you provide such
a macro?

Herbert
