Animator
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" }
