Description

The source of a node is in reference to where it came from; its origin. An enumeration defines the possibilities:

esriTinDensified - added by the triangulator along a breakline so that it may be Delaunay conforming.

esriTinIntersection - added by the triangulator where breaklines intersect.

esriTinOriginal - a mass point or breakline vertex handed to the triangulator as user data.

esriTinSuperNode - one of 4 nodes added far outside the declared data extent when a TIN is first created.

esriTinUnknown - undefined/unspecified, probably coming from a TIN stored on disk.

TINs do not yet persist node source information. It is only maintained while the TIN is is edit mode. This means after a TIN has been saved to disk, all nodes, except for super nodes, become unknown.
