Comment:
This passed all tests, and seems to work well for 3D polytopes, which was
the original request. It does fail for some 4D polytopes, for example for
one with vertices:
{{{[[99, 19, 38, 0],
[-85, -86, -72, 0],
[11, 31, 97, 0],
[61, 99, 28, 0],
[-50, -85, -90, 0],
[-29, -56, 96, 0],
[-48, 56, -83, 0],
[97, -42, 60, 0],
[-77, 73, 28, 0],
[41, -92, 27, 0],
[-34, 82, -58, 0],
[-81, 37, -93, 0],
[-96, 6, 11, 0],
[-93, 66, 88, 0],
[-35, -84, 77, 0],
[82, 83, -66, 0],
[-68, -72, -99, 0],
[89, -96, -97, 0],
[84, -92, -46, 0],
[88, 67, -18, 0],
[28, 93, 73, 0],
[-97, -14, -84, 0],
[97, 15, -61, 0],
[39, 92, -36, 0],
[-40, 99, 41, 0],
[-39, 56, 99, 0],
[-96, -85, -35, 0],
[-48, -18, 99, 0],
[91, 69, -95, 0],
[-73, 60, -36, 0],
[-65, -99, -32, 0],
[100, 4, 65, 0],
[32, 17, 94, 0],
[-86, -93, 34, 0],
[83, 48, -100, 0],
[75, -75, 100, 0],
[0, 0, 0, 1]]
}}}
I am happy to work on that if you (Arnaud) want; I didn't figure out why
it fails on that example.
