The -Y switch
- Suppresses the creation of
Steiner points on the exterior
boundary. Interior Steiner points may still be created.
- This switch is useful when the mesh boundary must be preserved so that
it conforms to some adjacent mesh.
- Specify this switch twice (`-YY') to prevent all segment splitting,
including interior boundaries.
- Be forewarned that you will probably sacrifice some of the quality of
the mesh; Triangle will try, but the resulting mesh may contain triangles
of poor aspect ratio. Works well if all the boundary vertices are closely
spaced.
- Be forewarned that the -Y switch can prevent the -D switch from
yielding a triangulation
that is conforming Delaunay.
- This switch will not disable the -s switch; if you don't want
vertices inserted on the boundary, use -Y and don't use -s.
