IPointFieldGeo	gauss(double threshold) alias of gaussianDecay
IPointFieldGeo	gaussian(double threshold) alias of gaussianDecay
IPointFieldGeo	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 pt, IVecI vel) get 3D vector field value
IVecI	getForce(IVecI v, IVecI orig) get original field value out of curve parameter u
IVecI	getForce(IVecI pos, IVecI vel, IVecI orig) get original field value out of curve parameter u
IPointFieldGeo	intensity(double i) set output intensity
IPointFieldGeo	linear(double threshold) alias of linearDecay
IPointFieldGeo	linearDecay(double threshold) set linear decay; When distance is equal to threshold, output is zero.
IPointFieldGeo	noDecay() set no decay
IVec	pos()
IPointFieldGeo	threshold(double t) set decay threshold
