Ah well that was embarrassing, but I appreciate the help.

The file I sent you was actually incorrect; I don't know why the 'w' coordinates had been zeroed, but the file I meant to send has the proper coordinates. However, adding the number of edges did fix my issue and Stella was able to move ...

I did specify the cells in the 4OFF, but it still gave the same error.

I'm trying to attach the file to this post, but it doesn't seem to accept any file extensions, I'll just email it to you.

Hello,

I have generated what should be a valid 4OFF file, however trying to open it within stella gives a popup with the text; 'CreateCells failed: coplanar faces?'. Is there a way to view which cell stella failed on? A debug log or something similar?

Thanks

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 ...

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 ...

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.

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 ...

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 ...
