Detailed Description
cell represents a parabolic, 18-node isoparametric wedge
vtkBiQuadraticQuadraticWedge is a concrete implementation of vtkNonLinearCell to represent a three-dimensional, 18-node isoparametric biquadratic wedge. The interpolation is the standard finite element, biquadratic-quadratic isoparametric shape function plus the linear functions. The cell includes a mid-edge node. 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 laying in quads 16-(0,1,4,3), 17-(1,2,5,4) and (2,0,3,5).

| int vtkBiQuadraticQuadraticWedge::CellBoundary | ( | int | subId, |
| double | pcoords[3], | ||
| vtkIdList * | pts | ||
| ) | [virtual] |
Given parametric coordinates of a point, return the closest cell boundary, and whether the point is inside or outside of the cell. The cell boundary is defined by a list of points (pts) that specify a face (3D cell), edge (2D cell), or vertex (1D cell). If the return value of the method is != 0, then the point is inside the cell.

| ) | [virtual] |
Generate contouring primitives. The scalar list cellScalars are scalar values at each cell point. The point locator is essentially a points list that merges points as they are inserted (i.e., prevents duplicates). Contouring primitives can be vertices, lines, or polygons. It is possible to interpolate point data along the edge by providing input and output point data - if outPd is NULL, then no interpolation is performed. Also, if the output cell data is non-NULL, the cell data from the contoured cell is passed to the generated contouring primitives. (Note: the CopyAllocate() method must be invoked on both the output cell and point data. The cellId refers to the cell from which the cell data is copied.)
Implements vtkCell.
| int vtkBiQuadraticQuadraticWedge::EvaluatePosition | ( | double | x[3], |
| double * | closestPoint, | ||
| int & | subId, | ||
| double | pcoords[3], | ||
| double & | dist2, | ||
| double * | weights | ||
| ) | [virtual] |
Given a point x[3] return inside(=1), outside(=0) cell, or (-1) computational problem encountered; evaluate parametric coordinates, sub-cell id (!=0 only if cell is composite), distance squared of point x[3] to cell (in particular, the sub-cell indicated), closest point on cell to x[3] (unless closestPoint is null, in which case, the closest point and dist2 are not found), and interpolation weights in cell. (The number of weights is equal to the number of points defining the cell). Note: on rare occasions a -1 is returned from the method. This means that numerical error has occurred and all data returned from this method should be ignored. Also, inside/outside is determine parametrically. That is, a point is inside if it satisfies parametric limits. This can cause problems for cells of topological dimension 2 or less, since a point in 3D can project onto the cell within parametric limits but be "far" from the cell. Thus the value dist2 may be checked to determine true in/out.

| double | pcoords[3], | ||
| double | x[3], | ||
| double * | weights | ||
| ) | [virtual] |
Determine global coordinate (x[3]) from subId and parametric coordinates. Also returns interpolation weights. (The number of weights is equal to the number of points in the cell.)
Implements vtkCell.
| int vtkBiQuadraticQuadraticWedge::Triangulate | ( | int | index, |
| vtkIdList * | ptIds, | ||
| vtkPoints * | pts | ||
| ) | [virtual] |
Generate simplices of proper dimension. If cell is 3D, tetrahedron are generated; if 2D triangles; if 1D lines; if 0D points. The form of the output is a sequence of points, each n+1 points (where n is topological cell dimension) defining a simplex. The index is a parameter that controls which triangulation to use (if more than one is possible). If numerical degeneracy encountered, 0 is returned, otherwise 1 is returned. This method does not insert new points: all the points that define the simplices are the points that define the cell.
Implements vtkCell.
| void vtkBiQuadraticQuadraticWedge::Derivatives | ( | int | subId, |
| double | pcoords[3], | ||
| double * | values, | ||
| int | dim, | ||
| double * | derivs | ||
| ) | [virtual] |
Compute derivatives given cell subId and parametric coordinates. The values array is a series of data value(s) at the cell points. There is a one-to-one correspondence between cell point and data value(s). Dim is the number of data values per cell point. Derivs are derivatives in the x-y-z coordinate directions for each data value. Thus, if computing derivatives for a scalar function in a hexahedron, dim=1, 8 values are supplied, and 3 deriv values are returned (i.e., derivatives in x-y-z directions). On the other hand, if computing derivatives of velocity (vx,vy,vz) dim=3, 24 values are supplied ((vx,vy,vz)1, (vx,vy,vz)2, ....()8), and 9 deriv values are returned ((d(vx)/dx),(d(vx)/dy),(d(vx)/dz), (d(vy)/dx),(d(vy)/dy), (d(vy)/dz), (d(vz)/dx),(d(vz)/dy),(d(vz)/dz)).
Implements vtkCell.
| virtual double* vtkBiQuadraticQuadraticWedge::GetParametricCoords | ( | ) | [virtual] |
Return a contiguous array of parametric coordinates of the points defining this cell. In other words, (px,py,pz, px,py,pz, etc..) The coordinates are ordered consistent with the definition of the point ordering for the cell. This method returns a non-NULL pointer when the cell is a primary type (i.e., IsPrimaryCell() is true). Note that 3D parametric coordinates are returned no matter what the topological dimension of the cell.
