It works adding the Q0 option. According to QHull manual Q0: "do not pre-me=
rge=20
facets with 'C-0' and Qx". C-0 and Qx options are by default used by qhull =
to=20
avoid precission errors. This errors can be avoided pre-merging coplanar=20
facets (C-0 & Qx) or using QJ option.=20
Again reading qhull manual: "Use option 'Qt' to triangulate all non-simplic=
ial=20
facets before generating results". So... Qt uses C-0 and Qx and only later =
it=20
"breaks" non-simplicial facets. Maybe this is why, since we read the qh=20
struct on memory rather than the final result of qhull this isn't working..=
=2E=20
It looks like there's a missing step.
This is as far as I've got...
