[pstricks] Help With Drawing Cyclodextrins

[rossi at york.cuny.edu]

Hello Everyone:

Can someone help me to use the tools of pstricks to draw a stilized version
of cyclodextrin molecules?  Please refer to

http://www.york.cuny.edu/~rossi/research/cyclodextrins.htm

for a few examples.

Basically, cyclodextrin molecules are truncated hollow cones constructed
from sucrose moities.  I am particularly interested in perspective views
and shading.  Please see the examples.

I really appreciate any help you are willing to provide.

Warm regards,

Angelo
