\title QtQuick.Particles Examples - CustomParticle
\example particles/customparticle
\brief This is a collection of examples using CustomParticle in the QML particle system.
\image qml-customparticle-example.png
This is a collection of small QML examples relating to using CustomParticle in the particle system.
Each example is a small QML file emphasizing a different way to use CustomParticle.
Blur Particles adds a blur effect to the particles, which increases over the particle's life time.
It uses a custom vertex shader:
\snippet examples/particles/customparticle/content/blurparticles.qml vertex
to propagate life time simulation to a custom fragement shader:
\snippet examples/particles/customparticle/content/blurparticles.qml fragment
which has access to both the normal image sampler and a blurred sampler, the image plus a ShaderEffect.
Fragment Shader just uses the particle system as a vertex delivery system.
\snippet examples/particles/customparticle/content/fragmentshader.qml 0
Image Colors uses CustomParticle to assign colors to particles based on their location in a picture.
The vertex shader,
\snippet examples/particles/customparticle/content/imagecolors.qml vertex
passes along the starting position for each vertex to the fragment shader,
\snippet examples/particles/customparticle/content/imagecolors.qml fragment
which uses it to determine the color for that particle.
