Description

When a TIN is initially constructed (with ITinEdit.InitNew) it contains four software generated points that reside far outside the declared data extent. These are connected into two triangles and this initial triangulation is what the user adds data to. The four software generated points are referred to as SuperNodes. The SuperNodeExtent is the minimum bounding rectangle that surrounds these points.
