Method Summary

void	applyField(IParticleI p)
I2DField	constantIntensity(boolean b) if output vector is besed on constant length (intensity) or variable depending geometry when curve or surface tangent is used
I2DFieldI	field()
I2DField	gaussian(double threshold) alias of gaussianDecay
I2DField	gaussianDecay(double threshold) set Gaussian decay with threshold; Threshold is used as double of standard deviation (when distance is eqaul to threshold, output is 13.5% of original).
IVec2I	get(IVecI pt) get field value at 3D location
double	intensity() get output intensity
I2DField	intensity(double i) set output intensity
I2DField	linear(double threshold) alias of linearDecay
I2DField	linearDecay(double threshold) set linear decay with threshold; When distance is equal to threshold, output is zero.
I2DField	noDecay() set no decay
double	threshold() get decay threshold
I2DField	threshold(double t) set decay threshold
