Does CDTriangulator2DExpAddOn.processLineAAImpl() try to check whether 2 triangles compose a rectangle? If it's the case and if the bug is in this part, it won't be hard to fix. The triangles must be in the same plane (use the plane equation composed of a normalized normal and a constant), they must have distinct right angles (use a dot product) and share the same hypotenuse (compare the vertices not on the right angles). As you talk about Delaunay, the limitation or bug is rather in CDTriangulator2D, isn't it?
