NDesiredDistanceForce Class

In This Topic

The NDesiredDistanceForce is a force, which couples an attraction force (edge force), and a repulsion force (vertex force). The two forces balance each other when the distance between connected vertices is equal to the specified desired distance.

Object Model

Syntax

Visual Basic
C#

'Declaration
 
<System.ComponentModel.TypeConverterAttribute(Nevron.Internal.jrhE)>
Public Class NDesiredDistanceForce 
   Inherits NForce
   Implements Nevron.Dom.INAttribute, Nevron.Dom.INHistoryCallback, Nevron.INReferenceHolder, Nevron.INReferenceProvider

'Usage
 
Dim instance As NDesiredDistanceForce

[System.ComponentModel.TypeConverter(Nevron.Internal.jrhE)]
public class NDesiredDistanceForce : NForce, Nevron.Dom.INAttribute, Nevron.Dom.INHistoryCallback, Nevron.INReferenceHolder, Nevron.INReferenceProvider

Remarks

The attraction force magnitute is computed by the following formula:

AttractionCoefficient * Math.Pow(distance, 2) / Math.Pow(DesiredDistance, 2)

The repulsion force magnitute is computed by the following formula:

RepulsionCoefficient * Math.Pow(DesiredDistance, 2) / Math.Pow(distance, 2)

Provided that the RepulsionCoefficient and AttractionCoefficient are equal, the two forces balance each other at DesiredDistance.
