glsl-hsl2rgb

HSL to RGB color conversion in GLSL.

#pragma glslify: hsl2rgb = require(glsl-hsl2rgb)

...
    //75deg hue, 50% sat, 25% lightness
    vec3 rgb = hsl2rgb(75.0/360.0, 0.5, 0.25);
    gl_FragColor = vec4(rgb, 1.0);

Implementation from flixel-gdx. PRs for optimizations welcome.

Usage

vec3 rgb = hsl2rgb(vec3 hsl)

Takes hsl vec3 and returns the rgb representation. Floats are expected in the 0.0 to 1.0 range.

vec3 rgb = hsl2rgb(float h, float s, float l)

Takes individual h, s, l arguments and returns the rgb representation. Exported for convenience.
