Method Summary

I2DSurfaceFieldGeo	bidirectional(boolean b) if bidirectional is on, field force vector is flipped when velocity of particle is going opposite
I2DSurfaceFieldGeo	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()
I2DSurfaceFieldGeo	gauss(double threshold) alias of gaussianDecay
I2DSurfaceFieldGeo	gaussian(double threshold) alias of gaussianDecay
I2DSurfaceFieldGeo	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 v) get 3D vector field value
IVec2I	get(IVecI pos, IVec2I uv) get original field value out of surface parameter uv
IVec2I	get(IVecI pos, IVecI vel) get 3D vector field value
