Hi,
This is a call to discuss the proposed RFC 64: Triangle, Polyhedral surface and
TIN
https://trac.osgeo.org/gdal/wiki/rfc64_triangle_polyhedralsurface_tin
~~~~~
Summary:
As of now, the OGRGeometry class (the base class from which all the subtypes
are derived) is
limited to OGRCompoundCurve, OGRCircularString, OGRLinearRing,
OGRMultiLineString,
OGRMultiPoint, OGRMultiPolygon, OGRMultiCurve, OGRSimpleCurve, OGRCurvePolygon
and
OGRPolygon.
This RFC addresses the addition of the following new geometries in OGRGeometry:
* Triangle - A subset of polygons, the fundamental difference is that it is
made of 3 nodes
only (actually 4, with the last one being the repetition of the first one) and
ONLY ONE
exterior boundary and NO interior polygons.
* PolyhedralSurface - A 3D figure made exclusively of Polygons.
* TriangulatedSurface - A subset of PolyhedralSurface; a 3D figure which
consists exclusively
of Triangles.

I've rebased and extended the work done by Avyav during last GSoc on top of
current trunk,
where it passes our continuous integration tests. I think we should consider
merging it soon
as it can easily rot if kept longer in a branch (the refresh from my previous
branch dating to
end of August was rather painful)
