Constructor Summary

IMeshFieldGeo(IMeshI m)

Method Summary

IMeshFieldGeo	bidirectional(boolean b) if bidirectional is on, field force vector is flipped when velocity of particle is going opposite
IMeshFieldGeo	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()
IMeshFieldGeo	gauss(double threshold) alias of gaussianDecay
IMeshFieldGeo	gaussian(double threshold) alias of gaussianDecay
IMeshFieldGeo	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(int vertexIdx)
IVecI	get(IVecI pos) get 3D vector field value
IVecI	get(IVecI pos, IVecI vel) get 3D vector field value
IMeshFieldGeo	intensity(double i) set output intensity
IMeshFieldGeo	linear(double threshold) alias of linearDecay
IMeshFieldGeo	linearDecay(double threshold) set linear decay; When distance is equal to threshold, output is zero.
IMeshFieldGeo	noDecay() set no decay
IMeshFieldGeo	threshold(double t) set decay threshold
