\title Qt Quick Examples - Shader Effects
\example shadereffects
\image qml-shadereffects-example.png
\brief A Qt Quick example demonstrating the use of shader effects.
\ingroup qtquickexamples
This example demonstrates a couple of visual effects that you can perform
with shaders in Qt Quick. It applies five different effects on a text and
a couple of images. For more information, visit
\l{Important Concepts In Qt Quick - Graphical Effects}
\include examples-run.qdocinc
\section1 Using ShaderEffect
The \l ShaderEffect type typically operates on other types, using a
\l ShaderEffectSource:
\snippet shadereffects/shadereffects.qml source
In the above snippet, \c theItem is the ID of a complex QML object in the
file.
ShaderEffects can use this ShaderEffectSource as a texture in their fragment
shader:
\snippet shadereffects/shadereffects.qml fragment
You can use any custom property on the ShaderEffect in your shader. This
makes animated shader code very easy:
\snippet shadereffects/shadereffects.qml properties
ShaderEffects can also have a custom vertext shader. Setting the mesh
property on ShaderEffect provides more vertices for you to manipulate,
enabling more effects.
\snippet shadereffects/shadereffects.qml vertex
