Window {visible: truewidth: 800height: 600title: Water Ripple EffectImage {id: sourceImgwidth: 800height: 600source: qrc:/12.png}ShaderEffectSource {id: shaderSourcesourceItem: sourceImglive: true}ShaderEffect {id: waterEffectanchors.fill: parentproperty variant sourceTexture: shaderSourceproperty real frequency: 10property real amplitude: 0.04property real time: 0.0NumberAnimation on time {from: 0.0to: Math.PI*2duration: 1000loops: Animation.Infinite}fragmentShader: varying highp vec2 qt_TexCoord0;uniform sampler2D sourceTexture;uniform highp float frequency;uniform highp float amplitude;uniform highp float time;void main() {highp vec2 pulse sin(time - frequency * qt_TexCoord0);highp vec2 coord qt_TexCoord0 amplitude * vec2(pulse.x, -pulse.x);gl_FragColor texture2D(sourceTexture, coord);}}
}效果如下-波涛汹涌
2.另一种效果纵向波纹
Window {visible: truewidth: 800height: 600title: Water Ripple EffectImage {id: sourceImgwidth: 800height: 600source: qrc:/12.png}ShaderEffectSource {id: shaderSourcesourceItem: sourceImglive: true}ShaderEffect {id: waterEffectanchors.fill: parentproperty variant sourceTexture: shaderSourceproperty real frequency: 10property real amplitude: 0.08property real time: 0.0NumberAnimation on time {from: 0.0to: Math.PI * 2duration: 1000loops: Animation.Infinite}fragmentShader: varying highp vec2 qt_TexCoord0;uniform sampler2D sourceTexture;uniform highp float frequency;uniform highp float amplitude;uniform highp float time;void main() {highp vec2 uv qt_TexCoord0;highp float wave sin(uv.y * frequency time) * amplitude;uv.x wave;gl_FragColor texture2D(sourceTexture, uv);}}
}效果-树的摇曳
修改下频率和振幅效果
property real frequency: 60
property real amplitude: 0.02这样看起来是不是有点波光粼粼的感觉了。挺有趣的~0…0 代码链接奉上感兴趣的可以研究玩玩 波纹效果代码地址
