StdRegions::Orientation Nektar::SpatialDomains::PointGeom::GetPointOrientation ( const SegGeom edge1,
const SegGeom edge2 
)
static

Get the orientation of point1; to be used later for normal convention.

If edge1 is connected to edge2 in the same direction as the points comprising edge1 then it is forward, otherwise it is backward.

For example, assume edge1 is comprised of points 1 and 2, and edge2 is comprised of points 2 and 3, then edge1 is forward.

If edge1 is comprised of points 2 and 1 and edge2 is comprised of points 3 and 2, then edge1 is backward.

Since both edges are passed, it does not need any information from the EdgeComponent instance.

Backward direction. Vertex 0 is connected to edge 2.
