Re: Problem with OFF files
Would it be possible to request a 4OFF of the aforementioned Waterman polytope? I have made some progess, but I am having an issue with the face enumeration. One type of face isn't adding up the way Stella is showing that it is. I understand this isn't really a pressing issue, but I though I would a...

Re: Problem with OFF files
My understand of Waterman polyhedra, is the CCP packing of spheres, (or in Stella's case cubes / rhombic dodecahedrons), whose origins lie within some bounding sphere of radius r. We can then raise these to the 4th dimension by representing the vertices of the convex hulls as (x, y, z, r) as mention...

Re: Problem with OFF files
I must be doing something wrong, I can never get the composition that Stella produces. I'll keep trying; I'm thinking it has to do with either the output from POV Ray or a combination of the proper switches passed to qhull.

Re: Problem with OFF files
You are correct; powershell was adding bytes to the qhull output. Piping the output from cmd worked. As a side note, how does Stella generate the 4D watermans? I have been trying to recreate some with a mix of the povray files on Paul Bourke's website and qhull, but I can never get the cells right a...

Problem with OFF files
Hello, I apologize if there is something here I missed, but I really cannot figure out what is wrong with my OFF files. Attempting to open them with Stella gives the error, "Error in file <file path>, line 1, There are no vertices". but the file looks find, and I have compared against an outputted O...
