Twirl image effect

Twirl image effect distorts the rendered image. Similar to Vortex, it distorts the image in a circular region.

Like all image effects, Twirl is available in Unity Pro only. Make sure to have the Pro Standard Assets installed.

Hardware support

Twirl works on graphics cards with support for pixel shaders (2.0). E.g. GeForce FX 5200 or Radeon 9500 and up. All image effects automatically disable themselves when they can not run on an end-users graphics card.
