I found the same question at
but there is no answer.
I try to get the identify-Information from a TIN, but I get an error.
With IRasterIdentifyObj2::GetPropAndValues(i, prop, val) all is OK on rasters. The same method exists on ITinIdentifyObj2, but there is always an HResult E_Fail when I try to query a TIN.
Any suggestions are welcome.
