Constructor Summary

IPointCloudFieldGeo(IVecI[] pts, IVecI[] fieldPts)

Method Summary

IPointCloudFieldGeo	bidirectional(boolean b) if bidirectional is on, field force vector is flipped when velocity of particle is going opposite
IPointCloudFieldGeo	constantIntensity(boolean b) if output vector is besed on constant length (intensity) or variable depending geometry when curve or surface tangent is used
void	del()
IPointCloudFieldGeo	gauss(double threshold) alias of gaussianDecay
IPointCloudFieldGeo	gaussian(double threshold) alias of gaussianDecay
IPointCloudFieldGeo	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	get(IVecI pos) get 3D vector field value
IVecI	get(IVecI pos, IVecI vel) get 3D vector field value
IPointCloudFieldGeo	intensity(double i) set output intensity
IPointCloudFieldGeo	linear(double threshold) alias of linearDecay
IPointCloudFieldGeo	linearDecay(double threshold) set linear decay; When distance is equal to threshold, output is zero.
IPointCloudFieldGeo	noDecay() set no decay
IPointCloudFieldGeo	threshold(double t) set decay threshold
