Triangle: -I switch (original) (raw)

The -I switch

Suppresses mesh iteration numbers.
Normally, this switch is used only when generating aDelaunay triangulation orconstrained Delaunay triangulation with no constraints on triangle quality or size.
Suppresses the output of .node and.poly files, so your input files won't be overwritten. (If your input is a .poly file that doesn't reference a.node file, then a .node file will be written.)
Cannot be used with the -r switch, because that would overwrite your input .ele file.
Shouldn't be used with the -q,-a, -u, or -s switch if you are using a .node file for input, because no .node file will be written, so there will be no record of any addedSteiner points.
