Constraint Edges – Example3

When you triangulate just the vertices of a polygon, it is not guaranteed that its edges are edges of the resulting Delaunay triagulation. But you can enforce edges in a triangulation as demonstrated in the below example where constraint edges are inserted into a 2D triangulation. Similarly you can insert breaklines into 2.5D triangle meshes,…Continue readingConstraint Edges – Example3

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…Continue readingBreaklines, ISO Contours and the Cookie Cutter
