Swirl
Note:There are also Cineversity videos for these special Node capsules, which demonstrate their practical use. Follow this link to the corresponding overview page.
This node works like a deformator and adds a twist and a height oscillation to the introduced geometry, similar to a water vortex. The effect runs out automatically with increasing distance from the Y-axis of the deformation matrix and can therefore be automatically restricted to a limited section of the geometry.
