Add Vertex

Add a Vertex

Use the Add Vertex option to insert a vertex into a triangulation. Triangles (facets) connecting the new vertex to the triangulation will be added automatically.

In most cases the new vertex will be internal to a single triangle, the triangle containing the new vertex will be replaced by three new triangles.

If the new vertex is close to an edge of the triangulation (in the edge tolerance) then the vertex will split and either four triangles will replace the two triangles that shared the edge (two triangles will be added if the edge segment is a boundary edge).
