Field Detail

noDecay

public static INoDecay noDecay

linearDecay

public static ILinearDecay linearDecay

gaussDecay

public static IGaussDecay gaussDecay

decay

public IFieldGeo.Decay decay

customDecay

public IDecay customDecay

threshold

public double threshold

threshold for decay. When decay is None, threshold isn't used. In case of Linear, when distance is equal to threshold, output is zero. In Gaussian, threshold is used as double of standard deviation (when distance is eqaul to threshold, output is 13.5% of original).

intensity

public double intensity

intensity of vector output

constantIntensity

public boolean constantIntensity

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

bidirectional

public boolean bidirectional

if bidirectional is on, field force vector is flipped when velocity of particle is going opposite
