Hi everobdy....
I have a TIN and a featureClass of polygons.
I want to create a elevation-surface law to describe each polygon.
For each polygon, I do this :
Dim pTinAdvanced As ITinAdvanced = pTin
Dim pEnumTinTriangle As IEnumTinTriangle = pTinAdvanced.MakeTriangleEnumerator(monCasier.Shape.Envelope, esriTinQualification.esriTinInsideDataArea, Nothing)
Dim pTinSurface As ITinSurface = pTin
Dim masurface2D As Double
pTinSurface.GetPartialVolumeAndArea(CType(maCote, Double), esriPlaneReferenceType.esriPlaneReferenceBelow, pEnumTinTriangle, pProjectedArea:=masurface2D)
However, the calculation is done on the envelopp of the polygon and not on the real shape !!!
How can I do the calculation on the real shape of the polygon and not on this envelopp ?
Thanks
