Detailed Description
Bilinear shape function on the square.Bilinear shape function on the square [-1, 1] x [-1, 1] (i.e. 4 element nodes) You will rarely use this class directly, but might plug it into your own FE traits class as shape_function_t.
Member Function Documentation
Returns the node index (on the element) of the node determined by face_index and face_node_index (on the boundary reference element). E.g. the vertex 1 (there are only vertices 0 and 1 on the boundary reference element) on the face 2 of the square reference element (there are 4 faces with indices from zero to 3) is mapped to vertex 3 on the reference element.
Reimplemented from imaging::ShapeFunction< 4, 2, 2 >.
