Detailed Description

cell represents a parabolic, isoparametric triangle

vtkBiQuadraticTriangle is a concrete implementation of vtkNonLinearCell to represent a two-dimensional, 7-node, isoparametric parabolic triangle. The interpolation is the standard finite element, bi-quadratic isoparametric shape function. The cell includes three mid-edge nodes besides the three triangle vertices and a center node. The ordering of the three points defining the cell is point ids (0-2,3-6) where id #3 is the midedge node between points (0,1); id #4 is the midedge node between points (1,2); and id #5 is the midedge node between points (2,0). id #6 is the center node of the cell.
