Description
The super nodes of a TIN have a Z value equal to NODATA. Mathmatical operations cannot be performed on NODATA. You can check this case by passing the Z to ITinAdvanced.IsVoidZ, ISurface.IsVoidZ, or ITinSurface.IsVoidZ for evaluation.
A super node is one of four nodes added by the software when a TIN is initially created (ITinEdit.InitNew). They reside far outside the declared data extent and are used to define an initial triangulation before user data gets added. Triangles incident to these nodes are always flagged as being outside the TIN's interpolation zone or data area.
