ISurfaceFieldGeo(ISurfaceI srf, ISurfaceI fieldSrf)

Method Summary

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