/**
* @class vtkThresholdPoints
* @brief extracts points whose scalar value satisfies threshold criterion
*
* vtkThresholdPoints is a filter that extracts points from a dataset that
* satisfy a threshold criterion. The criterion can take three forms:
* 1) greater than a particular value; 2) less than a particular value; or
* 3) between a particular value. The output of the filter is polygonal data.
