vtkLine

Section: Visualization Toolkit Filtering Classes

# Usage

vtkLine is a concrete implementation of vtkCell to represent a 1D line.

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

      obj = vtkLine

# Methods

The class vtkLine 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 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])`
