Hi everybody,<br>
I am having problem trying to get a constrained triangulation via vtkDelaunay2D.<br>
The constraints are passed as a set of closed polygons (as in
faultlines.tcl), and some of the polygons share one edge. I have
verified in the faultlines examples that this should not be a problem,
but some of edges in my polygons do not appear in the final
triangulation. This happens only with a few polygons while the others
(which also share an edge with some bigger common polygons) are
correctly triangulated.<br>
My question is: what the problem could be?<br>
<br>
I have thought of the points of the vertices which are shared, points
that are inevitably duplicated. But I think vtkDelaunay2D is
automatically merging coincident points.<br>
I could try to check if a point has already been inserted using
vtkPointLocator, but before i do this, IŽd like to know why
vtkDelaunay2D is working with no problems with the great majority of
polygons which share one edge.<br>
<br>
Thank you for any help<br>
