Usage

vtkQuadraticTriangle is a concrete implementation of vtkNonLinearCell to represent a two-dimensional, 6-node, isoparametric parabolic triangle. The interpolation is the standard finite element, quadratic isoparametric shape function. The cell includes three mid-edge nodes besides the three triangle vertices. The ordering of the three points defining the cell is point ids (0-2,3-5) 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).

To create an instance of class vtkQuadraticTriangle, simply invoke its constructor as follows

  obj = vtkQuadraticTriangle
