Constraint Edges – Example3

When you triangulate just the vertices of a polygon, it is not guaranteed that its edges are edges of the Delaunay triagulation. But you can insert them as Constraint Edges as demonstrated for a 2D triangulation and one segment below. Similarly you can insert breaklines into 2.5D triangle meshes, see Breaklines, ISO Contours and the…

Breaklines, ISO Contours and the Cookie Cutter

In the field of land surveying constraint edges are maybe better known as “breaklines”. Similarly to the 2D case you can insert them into the triangle mesh, forcing segment subdivision or not. In addition you can insert a segment with its original height or you can adjust its height to the triangulation. This results in…
