Field Detail

pt1

public IParticleOnCurveI pt1

pt2

public IParticleOnCurveI pt2

tension

public double tension

tension is a coefficient to convert distance of two points to amount of force.

constantTension

public boolean constantTension

if constantTension is true, amount of force is always constant and it's equals to tension. Only direction of force changes. But if the distance is zero, force is also zero.

maxTension

public double maxTension

isCurveClosed

public boolean isCurveClosed
