Usage

You can skip through the shaders with the mouse wheel.

Adding a new shader

• Add fragment shader and texture files
• Add header file for the new effect
• Add new effect to the effects enum in mainwindow.h
• Add new case in MainWindow::setEffect()
• Update CMakeLists.txt and resources.rc

See existing files for examples.

Currently supported Shadertoy variables

uniform vec3         iResolution              // viewport resolution (in pixels)
uniform float        iTime                    // shader playback time (in seconds)
uniform vec3         iChannelResolution[4]    // channel resolution (in pixels)
uniform vec4         iMouse                   // mouse pixel coords. xy: current (if MLB down), zw: click
uniform samplerXX    iChannel0..3             // input channel. XX = 2D/Cube
