Follow-up Comment #1, bug #38013 (project octave):
According to following code in libqhull (io.c / qh_printafacet), the setting
of facet->simplicial doesn't matters in 2D case.
case qh_PRINTincidences:
case qh_PRINToff:
case qh_PRINTtriangles:
if (qh hull_dim == 3 && format != qh_PRINTtriangles)
qh_printfacet3vertex(fp, facet, format);
else if (facet->simplicial || qh hull_dim == 2 || format == qh_PRINToff)
qh_printfacetNvertex_simplicial(fp, facet, format);
else
qh_printfacetNvertex_nonsimplicial(fp, facet, qh printoutvar++,
format);
break;
So I prepared a little patch. Hope it doesn't break others cases.
