Hello,
i could not find a function /flag in the mesher that identifies the boundary
edges, meaning edges that are part of the initial PLGS.
I saw that for a 3D mesh a IS_BOUNDARY type exists. but for 2d meshes i could not find an equivalence.
Do i have to check the boundary query by hand using geometric queries for the vertex points of the mesh and the edges of the original PLGS?
thanks a lot

Thanks for the reply.
the mesh_domain thus is a simple triangulation object.
One question remains: how do i identify if the newly inserted vertices (edge) is lying on the original boundary
triangulation identify the boudnary of the mesh domain

hello,
I am trying to make a simple 2D mesher for a FEM code using the cgal meshing capabilities.
I experimenteeeed with the meshing examples and demos. What i could not find in the
documentation and the examples is
How can i iterate through the mesh, Faces, Vertices, Edges?
Is there a method to determine if a edge/vertex lies on a boundary (meaning part of the CDT which is used as input
for the mesher?
Are there default io streams for the meshs?
It would be nice if anybody has some suggestions references for documentation etc on this topic.
Thanks a lot
best hansjoerg
