Method Summary
 IPointCloudFieldGeo bidirectional(boolean b)
          if bidirectional is on, field force vector is flipped when velocity of particle is going opposite

          if output vector is besed on constant length (intensity) or variable depending geometry when curve or surface tangent is used

 IPointCloudFieldGeo gauss(double threshold)
          alias of gaussianDecay
 IPointCloudFieldGeo gaussian(double threshold)
          alias of gaussianDecay
 IPointCloudFieldGeo 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).
