Twist Filter

Intro​

Rotate a Shape's materials around a centre point. The rotation is strongest at the Centre and falls off to zero at the Radius, creating a swirl or whirlpool effect.

UI​

Centre - Set the pivot point of the twist, where (0, 0) is the centre of the Shape.

Angle - Set the twist angle at the Centre, in degrees. The angle falls off to zero at the Radius.

Radius - Set the distance from the Centre, in pixels, at which the twist's Angle returns to zero.

Falloff - Set a shape to determine how the Angle falls off from the Centre to the Radius:

  • Linear - Fall off in a constant, linear way creating a hard transition at the edge of the Radius.
  • Smooth - Fall off smoothly.
  • Quadratic - Fall off steadily from the centre and then quickly towards the outside to create a soft transition beyond the distance from the Centre to the Radius.
