To create an instance of class vtkLine, simply invoke its constructor as follows
obj = vtkLine
obj
is an instance of the vtkLine class.
string = obj.GetClassName ()
int = obj.IsA (string name)
vtkLine = obj.NewInstance ()
vtkLine = obj.SafeDownCast (vtkObject o)
int = obj.GetCellType ()
- See the vtkCell API for descriptions of these methods.
int = obj.GetCellDimension ()
- See the vtkCell API for descriptions of these methods.
int = obj.GetNumberOfEdges ()
- See the vtkCell API for descriptions of these methods.
int = obj.GetNumberOfFaces ()
- See the vtkCell API for descriptions of these methods.
vtkCell = obj.GetEdge (int )
- See the vtkCell API for descriptions of these methods.
vtkCell = obj.GetFace (int )
- See the vtkCell API for descriptions of these methods.
int = obj.CellBoundary (int subId, double pcoords[3], vtkIdList pts)
- See the vtkCell API for descriptions of these methods.
obj.Contour (double value, vtkDataArray cellScalars, vtkIncrementalPointLocator locator, vtkCellArray verts, vtkCellArray lines, vtkCellArray polys, vtkPointData inPd, vtkPointData outPd, vtkCellData inCd, vtkIdType cellId, vtkCellData outCd)
- See the vtkCell API for descriptions of these methods.
int = obj.Triangulate (int index, vtkIdList ptIds, vtkPoints pts)
- See the vtkCell API for descriptions of these methods.
obj.Derivatives (int subId, double pcoords[3], double values, int dim, double derivs)
- See the vtkCell API for descriptions of these methods.
obj.Clip (double value, vtkDataArray cellScalars, vtkIncrementalPointLocator locator, vtkCellArray lines, vtkPointData inPd, vtkPointData outPd, vtkCellData inCd, vtkIdType cellId, vtkCellData outCd, int insideOut)
- Clip this line using scalar value provided. Like contouring, except
that it cuts the line to produce other lines.
int = obj.GetParametricCenter (double pcoords[3])
- Return the center of the triangle in parametric coordinates.
obj.InterpolateFunctions (double pcoords[3], double weights[2])
- Compute the interpolation functions/derivatives
(aka shape functions/derivatives)
obj.InterpolateDerivs (double pcoords[3], double derivs[2])
