To create an instance of class vtkSmoothErrorMetric, simply invoke its constructor as follows
obj = vtkSmoothErrorMetric
obj
is an instance of the vtkSmoothErrorMetric class.
string = obj.GetClassName ()
- Standard VTK type and error macros.
int = obj.IsA (string name)
- Standard VTK type and error macros.
vtkSmoothErrorMetric = obj.NewInstance ()
- Standard VTK type and error macros.
vtkSmoothErrorMetric = obj.SafeDownCast (vtkObject o)
- Standard VTK type and error macros.
double = obj.GetAngleTolerance ()
- Return the flatness threshold.
\post positive_result: result>90 && result<180
obj.SetAngleTolerance (double value)
- Set the flatness threshold with an angle in degrees. Internally
compute the cosine. value is supposed to be in ]90,180[, if not
it is clamped in [90.1,179.9].
For instance 178 will give better result than 150.
int = obj.RequiresEdgeSubdivision (double leftPoint, double midPoint, double rightPoint, double alpha)
- Does the edge need to be subdivided according to the cosine between
the two chords passing through the mid-point and the endpoints?
The edge is defined by its `leftPoint' and its `rightPoint'.
`leftPoint', `midPoint' and `rightPoint' have to be initialized before
calling RequiresEdgeSubdivision().
Their format is global coordinates, parametric coordinates and
point centered attributes: xyx rst abc de...
`alpha' is the normalized abscissa of the midpoint along the edge.
(close to 0 means close to the left point, close to 1 means close to the
right point)
\pre leftPoint_exists: leftPoint!=0
\pre midPoint_exists: midPoint!=0
\pre rightPoint_exists: rightPoint!=0
\pre clamped_alpha: alpha>0 && alpha<1
\pre valid_size: sizeof(leftPoint)=sizeof(midPoint)=sizeof(rightPoint)
=GetAttributeCollection()->GetNumberOfPointCenteredComponents()+6
double = obj.GetError (double leftPoint, double midPoint, double rightPoint, double alpha)
- Return the error at the mid-point. It will return an error relative to
the bounding box size if GetRelative() is true, a square absolute error
otherwise.
See RequiresEdgeSubdivision() for a description of the arguments.
