Constructor Detail

RepulsionlessSpring

public RepulsionlessSpring(float strengthConstant)

Creates a new Spring with the given strength

Parameters:

strengthConstant - k in Hooke's Law

Method Detail

setCluster

public void setCluster(Cluster root)

Specified by:

setCluster in class Force

setRepulsionForce

public void setRepulsionForce(RepulsionSpring repulsion)

set the repulsion force object to use if we are to ignore the effects of repulsion accross edges connected by springs... this can be done since the spring between edges can arguably be said to already separate the nodes enough. Note that we actually have to recalculate the repulsion accross the nodes so there is some minor cost to setting repulsion not null.

calculate

public void calculate()

Calculate node deltas due to spring forces between all nodes connected by an edge
