Method Summary

Methods

Modifier and Type	Method and Description
I2DCurveFieldGeo	bidirectional(boolean b) if bidirectional is on, field force vector is flipped when velocity of particle is going opposite
I2DCurveFieldGeo	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()
I2DCurveFieldGeo	gauss(double threshold) alias of gaussianDecay
I2DCurveFieldGeo	gaussian(double threshold) alias of gaussianDecay
I2DCurveFieldGeo	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).
IVec2I	get(IVecI pos) get 3D vector field value
IVec2I	get(IVecI pos, double u) get original field value out of curve parameter u
IVec2I	get(IVecI pos, IVecI vel) get 3D vector field value
IVec2I	get(IVecI pos, IVecI vel, double u) get original field value out of curve parameter u
I2DCurveFieldGeo	intensity(double i) set output intensity
I2DCurveFieldGeo	linear(double threshold) alias of linearDecay
I2DCurveFieldGeo	linearDecay(double threshold) set linear decay; When distance is equal to threshold, output is zero.
I2DCurveFieldGeo	noDecay() set no decay
I2DCurveFieldGeo	threshold(double t) set decay threshold
