Shader Library

A small collection of standalone GLSL fragment shaders. They compile with a standard resolution/time uniform set and write to gl_FragColor (or fragColor in the heartbeat shader).

Shaders

• AnimatedCircularGradient.h: radial gradient animated through time.
• CheckerBoard.h: procedural checkerboard.
• DynamicColourGradient.h: animated colour gradient.
• HypnosisSpiral.h: polar spiral driven by sine of angle and radius.
• LoopingGradient.h: smooth looping colour gradient.
• NoiseAnimation.h: animated pseudo-random noise field.
• ScanLines.h: scan-line effect.
• hearbeat.h: heartbeat-style waveform plot.

Usage

Each .h file contains a main() function. Drop the contents into any environment that provides:

uniformvec2 resolution;
uniformfloat time;

Examples: Shadertoy, openFrameworks, JUCE OpenGLComponent, custom engine.
