Impose boundaries for a triangulation via geometries instead of enforced edges #150

If I understood you right:
In that case what you can do is to combine boundary points and observation points in a single buffer (make sure there are no exact duplicates). You can then insert boundary edges as constraints and remove outer triangles and holes. |

Good morning,
we are evaluating CDT for generating a finite element mesh connecting observation locations for ocean surface temperature.
Accordingly to the kind of satellite we can have clouds of points or along track observations locations.
The relevant information is limited to the ocean and should not connect different basins or even different satellite tracks.
We are indeed needing a constrained triangulation, with boundaries and hole, but we do not know which vertices are to be considered as imposed edges.
It would be more natural to describe a geometry that provides the land boundaries or the tracks envelopes and ask the triangulation to cull the triangles whose edges would cross the imposed boundary lines. The actual mesh outer edge would be internal to our limiting geometries. I attach two images for clarifying the situation. I hope I have been clear enough.
Thank you
Andrea
