Distortion/Twist

A circular distortion is performed by the Twist function. The rotation angle is antiproportional to the distance of a pixel to the distortion's center, which makes the twist effect fade out at its outline.

	Increase the strength of the effect with the Amplify value. Set it to a negative number to twist clockwise.
	You can modify the rotation angles with the Transformator. Angles at the center of the twist effect supply the Input values at the right side of the graph, while the left values are located at the distortion's edge.
