Detailed Description

cell represents a parabolic, isoparametric edge

vtkQuadraticEdge is a concrete implementation of vtkNonLinearCell to represent a one-dimensional, 3-nodes, isoparametric parabolic line. The interpolation is the standard finite element, quadratic isoparametric shape function. The cell includes a mid-edge node. The ordering of the three points defining the cell is point ids (0,1,2) where id #2 is the midedge node.
