The -S switch
- Specifies the maximum number of
Steiner points that may be
inserted into the mesh (to meet the constraints on minimum
angle and maximum area). Type an integer after the -S switch.
- The default (when -S is not used) is to allow an unlimited number.
- If you specify this switch with no number after it, the limit is
set to zero.
- Triangle always adds points at segment
intersections, even if it needs to use more points than the limit
you set. When Triangle inserts segments by splitting (-s), it
always adds enough points to ensure that all the segments of the PSLG
are recovered, ignoring the limit if necessary.
- When the -S and -D switches are used together, be forewarned that
the -S switch may result in a conforming triangulation that is not
truly Delaunay, because Triangle may be forced to stop adding
points when the mesh is in a state where a segment is non-Delaunay
and needs to be split. If so, Triangle will print a warning.
