vtkImplicitDataSet computes the function (at the point x) by performing cell interpolation. That is, it finds the cell containing x, and then uses the cell's interpolation functions to compute an interpolated scalar value at x. (A similar approach is used to find the gradient, if requested.) Points outside of the dataset are assigned the value of the ivar OutValue, and the gradient value OutGradient.
To create an instance of class vtkImplicitDataSet, simply invoke its constructor as follows
obj = vtkImplicitDataSet
obj
is an instance of the vtkImplicitDataSet class.
string = obj.GetClassName ()
int = obj.IsA (string name)
vtkImplicitDataSet = obj.NewInstance ()
vtkImplicitDataSet = obj.SafeDownCast (vtkObject o)
long = obj.GetMTime ()
- Return the MTime also considering the DataSet dependency.
double = obj.EvaluateFunction (double x[3])
double = obj.EvaluateFunction (double x, double y, double z)
obj.EvaluateGradient (double x[3], double n[3])
obj.SetDataSet (vtkDataSet )
- Set / get the dataset used for the implicit function evaluation.
vtkDataSet = obj.GetDataSet ()
- Set / get the dataset used for the implicit function evaluation.
obj.SetOutValue (double )
- Set / get the function value to use for points outside of the dataset.
double = obj.GetOutValue ()
- Set / get the function value to use for points outside of the dataset.
obj.SetOutGradient (double , double , double )
- Set / get the function gradient to use for points outside of the dataset.
obj.SetOutGradient (double a[3])
- Set / get the function gradient to use for points outside of the dataset.
double = obj. GetOutGradient ()
- Set / get the function gradient to use for points outside of the dataset.
