Method Summary

Methods

Modifier and Type	Method and Description
ICurveFieldGeo	bidirectional(boolean b) if bidirectional is on, field force vector is flipped when velocity of particle is going opposite
ICurveFieldGeo	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()
ICurveFieldGeo	gauss(double threshold) alias of gaussianDecay
ICurveFieldGeo	gaussian(double threshold) alias of gaussianDecay
ICurveFieldGeo	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 v) get 3D vector field value
IVecI	get(IVecI v, double u) get original field value out of curve parameter u
IVecI	get(IVecI pos, IVecI vel) get 3D vector field value
IVecI	get(IVecI pos, IVecI v, double u) get original field value out of curve parameter u
ICurveFieldGeo	intensity(double i) set output intensity
ICurveFieldGeo	linear(double threshold) alias of linearDecay
ICurveFieldGeo	linearDecay(double threshold) set linear decay; When distance is equal to threshold, output is zero.
ICurveFieldGeo	noDecay() set no decay
ICurveFieldGeo	threshold(double t) set decay threshold
