shadertone

A Clojure library designed to mix Overtone Musical Synthesis and Shadertoy GLSL shaders.

Usage

Under Construction. See src/shadertone/core.clj See https://www.youtube.com/watch?v=UMg8Td5Gqhk

Building

To link in natives for LWJGL, until Leiningen gets better...do this for your platform after running lein deps.

Mac

> mkdir -p target/native/macosx/x86_64
> cd target/native/macosx/x86_64
> jar xf ~/.m2/repository/org/lwjgl/lwjgl/lwjgl-platform/2.8.5/lwjgl-platform-2.8.5-natives-osx.jar

Linux

> mkdir -p target/native/linux/x86_64
> cd target/native/linux/x86_64
> jar xf ~/.m2/repository/org/lwjgl/lwjgl/lwjgl-platform/2.8.5/lwjgl-platform-2.8.5-natives-linux.jar

Using

Hopefully, just copy over any www.shadertoy.com shader, load it and use Overtone to create some audio as input. lein swank or lein repl away...

Shader Inputs

From www.shadertoy.com:

uniform vec3      iResolution;     // viewport resolution (in pixels)
uniform float     iGlobalTime;     // shader playback time (in seconds)
TODO uniform float     iChannelTime[4]; // channel playback time (in seconds)
TODO uniform vec4      iMouse;          // mouse pixel coords. xy: current 
                                        // (if MLB down), zw: click
TODO uniform sampler2D iChannel[4];
TODO uniform vec4      iDate;           // (year, month, day, time in seconds)

Extras:

uniform float iOvertoneVolume; // tap of system volume
