Hi Artur,
When you are *retrieving* the IndexedGeometryArray from the
GeometryInfo, are you specifying the flag "USE_COORD_INDEX_ONLY"
as a parameter to geomInfo.getIndexedGeometryArray( flag..) ?
IIRC, it also takes other flags such as NIO, ByRef, etc.
If you're already aware of it, then please ignore.
What I did find though was that if you specified the COORD_INDEX_ONLY
flag while retrieving the IndexedGeometryArray, it takes a much
longer processing time than if you didn't. This is surprising since
the geometry would have already been converted to indexed triangles.
Don't know.....someone else probably does
Regards
Raj
