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.
Twirl image effect applied to the scene
| Radius | The radii of the ellipse where image distortion takes place. Radius of 0.5 is half the size of the screen. |
| Angle | Controls the amount of distortion applied. |
| Center | Position the distortion area on the screen. |
Hardware support
Twirl works on graphics cards with support for pixel shaders (2.0) or devices with OpenGLES 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.
