## Detailed Description

Animator types are different from normal Animation types. When using an Animator, the animation can be run in the render thread and the property value will jump to the end when the animation is complete.

The value of the QML property defining the uniform is updated after the animation has finished.

The following snippet shows how to use a UniformAnimator together with a ShaderEffect item.

     ShaderEffect {
         id: shader
         width: 50
         height: 50
         property variant t;
         UniformAnimator {
             target: shader
             uniform: "t"
             from: 0
             to: 1
             duration: 1000
             running: true
         }
         fragmentShader: "qrc:shader.frag.qsb"
     }

It is also possible to use the `on` keyword to tie the UniformAnimator directly to a uniform of a ShaderEffect instance.

     ShaderEffect {
         width: 50
         height: 50
         property variant t;
         UniformAnimator on t {
             from: 0
             to: 1
             duration: 1000
         }
         fragmentShader: "qrc:shader.frag.qsb"
     }

## Property Documentation

uniform : string

This property holds the name of the uniform to animate.

The value of the uniform must correspond to both a property on the target ShaderEffect and must be a uniform of type `float` in the fragment or vertex shader.
