/**
* @class vtkImplicitDataSet
* @brief treat a dataset as if it were an implicit function
*
* vtkImplicitDataSet treats any type of dataset as if it were an
* implicit function. This means it computes a function value and
* gradient. vtkImplicitDataSet is a concrete implementation of
* vtkImplicitFunction.
*
* 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.
*
* @warning
* Any type of dataset can be used as an implicit function as long as it
* has scalar data associated with it.
