To create an instance of class vtkQuadraticTriangle, simply invoke its constructor as follows
obj = vtkQuadraticTriangle
obj
is an instance of the vtkQuadraticTriangle class.
string = obj.GetClassName ()
int = obj.IsA (string name)
vtkQuadraticTriangle = obj.NewInstance ()
vtkQuadraticTriangle = obj.SafeDownCast (vtkObject o)
int = obj.GetCellType ()
- Implement the vtkCell API. See the vtkCell API for descriptions
of these methods.
int = obj.GetCellDimension ()
- Implement the vtkCell API. See the vtkCell API for descriptions
of these methods.
int = obj.GetNumberOfEdges ()
- Implement the vtkCell API. See the vtkCell API for descriptions
of these methods.
int = obj.GetNumberOfFaces ()
- Implement the vtkCell API. See the vtkCell API for descriptions
of these methods.
vtkCell = obj.GetEdge (int edgeId)
- Implement the vtkCell API. See the vtkCell API for descriptions
of these methods.
vtkCell = obj.GetFace (int )
int = obj.CellBoundary (int subId, double pcoords[3], vtkIdList pts)
obj.Contour (double value, vtkDataArray cellScalars, vtkIncrementalPointLocator locator, vtkCellArray verts, vtkCellArray lines, vtkCellArray polys, vtkPointData inPd, vtkPointData outPd, vtkCellData inCd, vtkIdType cellId, vtkCellData outCd)
int = obj.Triangulate (int index, vtkIdList ptIds, vtkPoints pts)
obj.Derivatives (int subId, double pcoords[3], double values, int dim, double derivs)
obj.Clip (double value, vtkDataArray cellScalars, vtkIncrementalPointLocator locator, vtkCellArray polys, vtkPointData inPd, vtkPointData outPd, vtkCellData inCd, vtkIdType cellId, vtkCellData outCd, int insideOut)
- Clip this quadratic triangle using scalar value provided. Like
contouring, except that it cuts the triangle to produce linear
triangles.
int = obj.GetParametricCenter (double pcoords[3])
- Return the center of the quadratic triangle in parametric coordinates.
double = obj.GetParametricDistance (double pcoords[3])
- Return the distance of the parametric coordinate provided to the
cell. If inside the cell, a distance of zero is returned.
obj.InterpolateFunctions (double pcoords[3], double weights[6])
- Compute the interpolation functions/derivatives
(aka shape functions/derivatives)
obj.InterpolateDerivs (double pcoords[3], double derivs[12])
