+\section interpolation2D1D Special features of 2D linear/surface intersectors
+
+It is possible to get back the matrix of intersection segments in 2D
+of a linear source mesh and a surface target mesh.
+The corresponding intersector class is Planar2D1DIntersectorP0P0.
+The limitations are:
+- only P0->P0 intersection
+- only geometric type Geometric2D
+
+It is possible to get back the linear source elements which are common
+at least between two surface target elements.

\section interpolation3Dsurf Special features of 3D surface intersectors
When remapping a three dimensional surfaces, one should give a meaning to the area of intersection between two three-dimensional non coplanar polygons. A projection phase is thus necessary to have both polygons on the same plane. Care must be taken when defining this projection to avoid non conservative remappings. After the projection step, the source and target cells lie in the same plane and the same algorithms as for 2D remapping can be employed.
