Displace - Drift and Spin

The Displace category offers a wide variety of motion effects you can adjust and use on both Particular and Form-based behaviors. It's a combination of effects that were available in Particular and Form allowing for the creation of a new evolved section where we can mix these properties.

The first categories we'll look at are Drift and Spin.

Drift

Drift X, Y, Z controls push the particles uniformly in the X, Y or Z direction. This was how Wind behaved in  previous versions of Particular. When opening a project from a version prior to Particular 5, any Wind settings have migrated to Drift.

Spin

Spin Amplitude

Spin Amplitude makes particles move in randomized, circular orbits. A value of 0 turns off the spinning motion. Low values make small circular orbits. High values make large circular orbits. This behavior is useful for adding randomness to particle motion, which makes the animation look more natural. Amplitude can also be used to create a swarming look.

Spin Frequency

Spin Frequency sets how fast the spinning particles move in their orbit. Low values mean the particles spin slowly in their orbit. Higher values make the particles spin faster. The clips below were rendered with Motion Blur to show the motion clearly.

Amplitude off No spin	Frequency low Amplitude 100	Frequency high Amplitude 100

Fade-in Spin (seconds)

Fade-in Spin (measured in seconds) sets how long the particle lives before it is fully affected by the spin. High values mean the spin takes a while to affect the particles, which makes the animation fade in gradually overtime.
