TinTriangleEnumerator Class

The Esri TinTriangleEnumerator component.

TinTriangleEnumerator is a non-creatable object. References to non-creatable objects must be obtained through other objects.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.


The TinTriangleEnumerator object is used for iterative TinTriangle processing on TINs. For example, to return all triangles within the interpolation zone (domain) of a TIN or the triangles of a TinPolygon. TinFilters, like TinValueFilter and TinDataElementFilter are used to control which triangles are passed back by the enumerator. Custom, application specific, filters can be used as well.

The TinTriangleEnumerator object isn't co-creatable. Other functions are used to create it. Tin and TinPolygon objects can create and return TinTriangleEnumerators.

Supported Platforms

Windows, Solaris, Linux

Extended Error Information

Use the ISupportErrorInfo method InterfaceSupportsErrorInfo to determine if the object supports extended error information. If the object supports extended error info, VC++ developers should use the OLE/COM IErrorInfo interface to access the ErrorInfo object. Visual Basic developers should use the global error object Err to retrieve this extended error information.


Interfaces Description
IEnumTinElement Provides access to TIN element options.
IEnumTinTriangle Provides access to members that control TIN triangle enumerators.
ISupportErrorInfo Indicates whether a specific interface can return Automation error objects.
