EnableThresholding Property

Summary

Gets or sets the value that indicates whether to enable or disable the thresholding feature.

Syntax

C++

public bool EnableThresholding { get; set; }

  
Public Property EnableThresholding As Boolean

public: 
property bool EnableThresholding { 
   bool get(); 
   void set (    bool ); 
}

Property Value

True to enable thresholding; false to disable thresholding.

Remarks

The thresholding (or binary segmentation) feature allows you to remove a certain density from a 3D object by specifying an interval (which is between LowerThreshold and UpperThreshold). Any value outside this interval will not be rendered.
If the thresholding feature is disabled, the values of the LowThreshold and UpperThreshold will be saved for later use when the thresholding feature is enabled.
