### Installation :package:

```bash
npm i glsl-grid -S
```

### Usage :book:

#### grid(vec3 pos, vec3 axis, float size)
- vec3 pos
The position in world space.
- vec3 axis
The axis to draw a grid for. Set to 1.0 to enable, 0.0 to disable. i.e. vec3(0.0, 0.0, 1.0) will draw only along the z axis.
- float size
Space between grid tiles.

### Example :floppy_disk:

```glsl
#pragma glslify: grid = require(glsl-grid)
varying vec3 vPos;

void main() {
    float lines = grid(vPos, vec3(0.0, 0.0, 1.0), 2.0);
    gl_FragColor = vec4(vec3(lines), 1.0);
}
```
