Description

Returns a triangle enumerator that honors the constraints defined by the input arguments.

The pAreaOfInterest argument is an envelope that defines the area for which elements will be returned. Only triangles that fall inside the envelope qualify. The argument can be set to a Null pointer ('Nothing' in VB) in which case the TIN's data extent will be used.

The Criteria argument takes an esriTinQualification enumeration. The possible values for triangles are esriTinAll, esriTinInsideTin, esriTinInsideDataArea.

The pFilter argument is an additional constraint that can be applied. Any valid TinFilter can be used. Pass a Null pointer ('Nothing' in VB) if  you don't want to apply a filter.
