vtkPolyLine

Section: Visualization Toolkit Filtering Classes

# Usage

vtkPolyLine is a concrete implementation of vtkCell to represent a set of 1D lines.

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

      obj = vtkPolyLine

# Methods

The class vtkPolyLine has several methods that can be used. They are listed below. Note that the documentation is translated automatically from the VTK sources, and may not be completely intelligible. When in doubt, consult the VTK website. In the methods listed below, `obj` is an instance of the vtkPolyLine class.

- `string = obj.GetClassName ()`
- `int = obj.IsA (string name)`
- `vtkPolyLine = obj.NewInstance ()`
- `vtkPolyLine = 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.
- `obj.Clip (double value, vtkDataArray cellScalars, vtkIncrementalPointLocator locator, vtkCellArray lines, vtkPointData inPd, vtkPointData outPd, vtkCellData inCd, vtkIdType cellId, vtkCellData outCd, int insideOut)` - 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.
- `int = obj.IsPrimaryCell ()` - Return the center of the point cloud in parametric coordinates.
- `int = obj.GetParametricCenter (double pcoords[3])` - Return the center of the point cloud in parametric coordinates.
- `obj.InterpolateFunctions (double pcoords[3], double weights)` - Compute the interpolation functions/derivatives (aka shape functions/derivatives)
- `obj.InterpolateDerivs (double pcoords[3], double derivs)` - Compute the interpolation functions/derivatives (aka shape functions/derivatives)
