# Mixbox for Javascript
```html
```
```javascript
import mixbox from 'https://scrtwpns.com/mixbox.esm.js'; // for ES6 module use this instead
```
### Node
```
npm install mixbox
```
```javascript
import mixbox from 'mixbox';
```
## Usage
```javascript
var rgb1 = "rgb(0, 33, 133)"; // blue
var rgb2 = "rgb(252, 211, 0)"; // yellow
var t = 0.5; // mixing ratio
var mixed = mixbox.lerp(rgb1, rgb2, t);
console.log(mixed);
```
## Mixing Multiple Colors
```javascript
var z1 = mixbox.rgbToLatent(rgb1);
var z2 = mixbox.rgbToLatent(rgb2);
var z3 = mixbox.rgbToLatent(rgb3);
var zMix = new Array(mixbox.LATENT_SIZE);
for (var i = 0; i < zMix.length; i++) { // mix:
zMix[i] = (0.3*z1[i] + // 30% of rgb1
0.6*z2[i] + // 60% of rgb2
0.1*z3[i]); // 10% of rgb3
}
var rgbMix = mixbox.latentToRgb(zMix);
```

## Mixbox in WebGL
```javascript
var shader = `
precision highp float;
// uncomment the following line if you work in linear space
// #define MIXBOX_COLORSPACE_LINEAR
uniform sampler2D mixbox_lut; // bind mixbox.lutTexture(gl) here
#include "mixbox.glsl"
void main(void) {
vec3 rgb1 = vec3(0, 0.129, 0.522); // blue
vec3 rgb2 = vec3(0.988, 0.827, 0); // yellow
float t = 0.5; // mixing ratio
vec3 rgb = mixbox_lerp(rgb1, rgb2, t);
gl_FragColor = vec4(rgb, 1.0);
}
`;
shader = shader.replace('#include "mixbox.glsl"', mixbox.glsl());
```
```javascript
gl.useProgram(shaderProgram);
gl.activeTexture(gl.TEXTURE0);
gl.bindTexture(gl.TEXTURE_2D, mixbox.lutTexture(gl));
gl.uniform1i(gl.getUniformLocation(shaderProgram, "mixbox_lut"), 0);
```
