Constructor Summary

IAttractorGeo(IVecI p)

Method Summary

IAttractorGeo	bidirectional(boolean b) if bidirectional is on, field force vector is flipped when velocity of particle is going opposite
IAttractorGeo	constantIntensity(boolean b) if output vector is besed on constant length (intensity) or variable depending geometry when curve or surface tangent is used
IAttractorGeo	gauss(double threshold) alias of gaussianDecay
IAttractorGeo	gaussian(double threshold) alias of gaussianDecay
IAttractorGeo	gaussianDecay(double threshold) set Gaussian decay; Threshold is used as double of standard deviation (when distance is eqaul to threshold, output is 13.5% of original).
IVecI	getForce(IVecI v, IVecI orig) get original field value out of curve parameter u
IAttractorGeo	intensity(double i) set output intensity
IAttractorGeo	linear(double threshold) alias of linearDecay
IAttractorGeo	linearDecay(double threshold) set linear decay; When distance is equal to threshold, output is zero.
IAttractorGeo	noDecay() set no decay
IAttractorGeo	threshold(double t) set decay threshold
