To create an instance of class vtkVertex, simply invoke its constructor as follows
obj = vtkVertex
obj
is an instance of the vtkVertex class.
string = obj.GetClassName ()
int = obj.IsA (string name)
vtkVertex = obj.NewInstance ()
vtkVertex = 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.
obj.Clip (double value, vtkDataArray cellScalars, vtkIncrementalPointLocator locator, vtkCellArray pts, vtkPointData inPd, vtkPointData outPd, vtkCellData inCd, vtkIdType cellId, vtkCellData outCd, int insideOut)
- See the vtkCell API for descriptions of these methods.
int = obj.CellBoundary (int subId, double pcoords[3], vtkIdList pts)
- 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 vertex
(1D cell). If the return value of the method is != 0, then the point is
inside the cell.
obj.Contour (double value, vtkDataArray cellScalars, vtkIncrementalPointLocator locator, vtkCellArray verts1, vtkCellArray lines, vtkCellArray verts2, vtkPointData inPd, vtkPointData outPd, vtkCellData inCd, vtkIdType cellId, vtkCellData outCd)
- 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).
int = obj.GetParametricCenter (double pcoords[3])
- Return the center of the triangle in parametric coordinates.
int = obj.Triangulate (int index, vtkIdList ptIds, vtkPoints pts)
- Triangulate the vertex. This method fills pts and ptIds with information
from the only point in the vertex.
obj.Derivatives (int subId, double pcoords[3], double values, int dim, double derivs)
- Get the derivative of the vertex. Returns (0.0, 0.0, 0.0) for all
dimensions.
obj.InterpolateFunctions (double pcoords[3], double weights[1])
- Compute the interpolation functions/derivatives
(aka shape functions/derivatives)
obj.InterpolateDerivs (double pcoords[3], double derivs[3])
