NSpringForce Class

In This Topic

The NSpringForce class represents an edge force, which simulates a spring connecting adjacent vertices.

Object Model

Syntax

Visual Basic
C#

'Declaration
 
Public Class NSpringForce 
   Inherits NForce
   Implements Nevron.Nov.Dom.INDomDeepEquals, Nevron.Nov.Dom.INDomDeeplyCloneable, Nevron.Nov.INDeeplyCloneable

'Usage
 
Dim instance As NSpringForce

public class NSpringForce : NForce, Nevron.Nov.Dom.INDomDeepEquals, Nevron.Nov.Dom.INDomDeeplyCloneable, Nevron.Nov.INDeeplyCloneable

Remarks

The spring force magnitude formula can take two forms based on the SpringForceLaw property value:

edge.SpringStiffness * Math.Log(distance / edge.SpringLength)
edge.SpringStiffness * (d - edge.SpringLength)

In both forms the spring force becomes repulsive, if the distance is smaller than the spring length, and becomes attractive, when the distance is larger than the spring length. That is, the spring force aims to make the distance between connected vertices equal to the natural (zero energy) of the spring.

The SpringStiffness and SpringLength parameters can be specified on a per edge basis. If an edge does not provide a concrete value for either of these parameters, the default values are obtained from the SpringStiffness and SpringLength properties respectively.
