Twist Deformation
Rotates each point around the origin with a rotation angle that depends on its distance from the centre. Points near the centre twist the most; points beyond the configured radius are untouched.

Parameters
Twist Deformation parameters
Strength- Maximum rotation angle at the centre, in radians. Range −5 to 5, default 1 (≈57°). Positive values twist counter-clockwise; negative values twist clockwise. The rotation falls off linearly to 0 at
Radiusdistance from the centre. Radius- Radius beyond which points are untouched, in mm. Range 10–500, default 100. Points farther than this stay in place; points closer rotate proportionally more.
Rotation formula: angle(p) = (1 − dist(p) / Radius) × Strength if dist(p) < Radius, else 0.
Typical use
- Hurricane / vortex effects on top of Radial Lines or Grid Lattice.
- Galaxy-style swirls from a Parallel Lines generator.
- Pinch / twist corner distortions at high strength.
