Strand Sin Wave Movement

 
 
 

This compound animates the strand using the mathematical sine function, which creates an undulating wave motion. You can use this compound to animate the strands when using an unsimulated ICE tree (such as if the point cloud's ICETree node is in the Modeling region).

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].

Tasks: Particles/Strands

Output Ports: Execute

Num Waves

The number of waves created along the strand. One wave is one period of a sine wave.

Local Direction

The direction in which the sine wave moves according to the particle's local axis you specify here.

Wave Strength Profile

This curve defines the amplitude of the sine wave, starting from the strand's base (key on the left) to the tip (key on the right).

Wave Strength Multiplier

Multiplies the sine wave strength value set with the profile curve.

Select Wave Speed Method

Select the method by which the wave speed is calculated:

  • Use Wave Speed uses the Wave Speed value defined below.

  • Use Particle Velocity Multiplied by Wave Speed uses the current velocity of the particles multiplied by the Wave Speed value defined below.

Wave Speed

Determines how quickly the number of waves is created along the strand (like wave frequency).

Wave Timing Offset

Offsets the timing of the sine waves along the strands so that the strands don't all have the same sine wave movement at the same time.
