Turbulize Strands

This compound animates the strand using turbulence, which modifies the movement based on noise.

Create strands, then plug this compound's Execute output into a PostSimExecute port on the Simulation Root node or in a port on the ICETree node.

For information, see Shaping the Strands [ICE Particle Simulations].

Turbulence Scale	The amount of turbulence applied to the strand.
Animated	Toggles the activeness of the Animation Speed parameter. You can use these options to animate the strands with turbulence when using an unsimulated ICE tree (such as if the point cloud's ICETree node is in the Modeling region).
Animation Speed	If you selected Animated, you can change the noise frequency of the turbulence over time. This value is the speed at which the noise evolves.
Complexity	Adds a fractal-like complexity to the noise which increases the level of detail.
NoiseType	Uses either the Simplex or Perlin type of noise calculations. Perlin noise has spatial coherence, meaning that several different points in roughly the same location in space tend to have similar noise added to them. It interpolates between the random values. Perlin noise can help make objects more natural-looking by imitating the controlled random appearance of elements found in nature; that is, there is structure to the noise while still appearing fairly random. Simplex noise is similar to Perlin noise, but is less computationally complex. This is because it divides the space into equilateral triangles to interpolate between, which reduces the number of data points. This makes Simplex noise useful for producing noise over large spatial areas. Simplex noise has a well-defined and continuous gradient everywhere that can be computed fairly quickly, and has no noticeable directional artifacts.
Turbulence Strength Profile	This curve defines how the turbulence strength is applied along the strand, starting from the strand's base (key on the left) to the tip (key on the right).
Strength Multiplier	Multiplies the turbulence strength value set with the profile curve.
Turbulence Movement Direction	The direction in which the turbulence moves on the strand, according to the particle's local XYZ axis you specify here. The Y axis makes the turbulence move along the length of the strand.
Turbulence Movement Speed	Determines how quickly turbulence moves along the strand.
