Threshold Property

Gets or sets the (ISO threshold) for the mesh.

Syntax

C#
Visual Basic
Objective-C
Java
C++

public int Threshold {get; set;}

'Declaration
 
Public Property Threshold As Integer

'Usage
 
Dim instance As Medical3DSSD
Dim value As Integer
 
instance.Threshold = value
 
value = instance.Threshold

public:
property int Threshold {
   int get();
   void set (    int value);
}

Property Value

Value that represents the (ISO threshold) for the mesh.

Remarks

The threshold value must be between the Medical3DObject.MinimumValue and Medical3DObject.MaximumValue.
Setting this value to a high number will make the resultant object display the hard tissue surface (for example, bones). Setting this value to a small value will make the resultant object display the soft tissues.
