vtkQuadraticHexahedron

Section: Visualization Toolkit Filtering Classes

Usage

vtkQuadraticHexahedron is a concrete implementation of vtkNonLinearCell to represent a three-dimensional, 20-node isoparametric parabolic hexahedron. The interpolation is the standard finite element, quadratic isoparametric shape function. The cell includes a mid-edge node. The ordering of the twenty points defining the cell is point ids (0-7,8-19) where point ids 0-7 are the eight corner vertices of the cube; followed by twelve midedge nodes (8-19). Note that these midedge nodes correspond lie on the edges defined by (0,1), (1,2), (2,3), (3,0), (4,5), (5,6), (6,7), (7,4), (0,4), (1,5), (2,6), (3,7).

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

  obj = vtkQuadraticHexahedron
