Wrong node numbering in vtkBiQuadraticQuadraticWedge documentation
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
For vtkBiQuadraticQuadraticWedge (a 18-noded wedge cell), the documentation reads: The ordering of the 18 points defining the cell is point ids (0-5,6-15, 16-18) where point ids 0-5 are the six corner vertices of the wedge; followed by nine midedge nodes (6-15) and 3 center-face nodes. Note that these midedge nodes correspond lie on the edges defined by (0,1), (1,2), (2,0), (3,4), (4,5), (5,3), (0,3), (1,4), (2,5), and the center-face nodes are lieing in quads 16-(0,1,4,3), 17-(1,2,5,4) and (2,0,3,5).
which is wrong, since the maximum point id has to be 17, not 18. The documentation section with correct numbering is the following:
The ordering of the 18 points defining the cell is point ids (0-5,6-14, 15-17) where point ids 0-5 are the six corner vertices of the wedge; followed by nine midedge nodes (6-14) and 3 center-face nodes. Note that these midedge nodes correspond lie on the edges defined by (0,1), (1,2), (2,0), (3,4), (4,5), (5,3), (0,3), (1,4), (2,5), and the center-face nodes are lieing in quads 15-(0,1,4,3), 16-(1,2,5,4) and 17-(2,0,3,5).
