| 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.
Implements vtkCell.
| void vtkEmptyCell::EvaluateLocation | ( | int & | subId, |
| 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 vtkEmptyCell::IntersectWithLine | ( | double | p1[3], |

| double | tol, | ||
| double & | t, | ||
| double | x[3], | ||
| double | pcoords[3], | ||
| int & | subId | ||
| ) | [virtual] |
Intersect with a ray. Return parametric coordinates (both line and cell) and global intersection coordinates, given ray definition and tolerance. The method returns non-zero value if intersection occurs.
Implements vtkCell.
| int vtkEmptyCell::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 vtkEmptyCell::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 void vtkEmptyCell::InterpolateFunctions | ( | double | pcoords[3], |
| double * | weights | ||
| ) | [virtual] |
Compute the interpolation functions/derivatives (aka shape functions/derivatives)
| virtual void vtkEmptyCell::InterpolateDerivs | ( | double | pcoords[3], |
| double * | derivs | ||
| ) | [virtual] |
Compute the interpolation functions/derivatives (aka shape functions/derivatives)
