void ThresholdByUpper(float upper);
void ThresholdBetween(float lower, float upper);
float GetUpperThreshold();
float GetLowerThreshold();
DESCRIPTION
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.
void ThresholdByLower(float lower)
Criterion is cells whose scalars are less than lower threshold.
void ThresholdByUpper(float upper)
Criterion is cells whose scalars are less than upper threshold.
void ThresholdBetween(float lower, float upper)
Criterion is cells whose scalars are between lower and upper thresholds.
