KinkOp

Applies lateral noise along each curve.

Inputs

Each curve in the Input Curves is deformed to wander near its original path.

Parameters

The approximate amplitude of radial distance that each output curve is allow to deviate from the original centerline is a ramp from the Amplitude Root to Tip. The ramp can be made non-linear with Gamma and also given some Random noise. The effect can be limited by axis with the vector Amplitude Scale, where X is the tangent, Y is the curves facing direction, and Z is perpendicular to the facing direction.

The approximate frequency of of wandering back and forth that each output curve follows around the original centerline is a ramp from the Frequency Root to Tip. The ramp can be made non-linear with Gamma. The effect can be limited by axis with the vector Frequency Scale, where X is the tangent, Y is the curves facing direction, and Z is perpendicular to the facing direction.

For the axis scaling features, the primitive vector Facing Attribute specfies a facing direction, perpendicular to the tangent.
