Swirly
The Swirly generator creates an animated pattern in one of three different styles called
Pulse, Spiderweb Spin, and Spiky. Once you select a style, you can modify and animate
the scale, rotation, persistence, radius, amplitude, and number of passes of the pattern.
Parameters in the Inspector
Scale: Sets the size of the swirly shape.
Rotation: Sets the rotation of the initial shape.
Persistence: Sets the number of times the shape is repeated.
Minimum Radius: Sets the minimum radius of the initial shape.
Radius Amplitude: Sets the amplitude of the whole shape.
Amplitude: Sets the amplitude of the waves that make up the shape.
Passes: Sets the number of shapes morphing at one time.
Style: Sets the style of Swirly–Pulse, Spiderweb Spin, or Spiky.
