- There is a mail-based file server : netlib@ornl.gov
- Send it a one-line message of SEND INDEX
- This will return a help file pretty quickly to you with an
- index to all the libraries on the server. The one that will be of
- use to you is the POLYHEDRA library. BTW leave the subject line
- blank, even though I think it is ignored anyway.
-
- To get an index of the polyhedra on the server, send the message :
- SEND INDEX FROM POLYHEDRA
- This will return you a list of all the polyhedra with their names.
-
- For example, to get the data for the icosahedron, send the message :
- SEND 4 FROM POLYHEDRA
- (The polyhedra are numbered)
- These files contain the vertex data and the face data, as well as
- dihedral angles, the names of the duals, and also in some cases
- the expression for the vertex data rather than just the numerical
- approximation.
-
- Also mentioned in the index, is the source code and manual for the
- program that created these files.
-
-
- Another possibility is a recent program called Kaleido that creates
- all the polyhedra on the netlib server and more. This along with
- a thesis describing the technique, the source code, the pre-calculated
- data, and postscript wireframe drawings of each polyhedron, is
- available at gauss.technion.ac.il in the directory /kaleido
- This doesn't include the vertex data, you are supposed to be able
- to calculate it from the data produced (but it beats me how :-)
-
-
- Hope this helps !
