# Doodle3D-Slicer
The Doodle3D Slicer is designed for developers to make it easier to export 3d models to the Doodle3D WiFi-Box. The slicers includes a gcode slicer and a class designed for communication with the WiFi-Box. All the classes are in the D3D name space.
Three.js, Clipper.js and jQuery are required to run the Doodl3D slicer. All are included in the source.
This is an example of code.
JavaScript gcode slicer, Intended to use with the Doodle3D WiFi-Box
# Usage
```javascript
var localIp = "192.168.5.1";
var doodleBox = new D3D.Box(localIp);
import * as THREE from 'three';
import { defaultSettings, Slicer } from 'Doodle3D/Doodle3D-Slicer';
doodleBox.onload = function () {
"use strict";
var printer = new D3D.Printer(printerSettings, userSettings);
var geometry = new THREE.BoxGeometry(20, 20, 20, 1, 1, 1);
var material = new THREE.MeshBasicMaterial({color: 0x000000, wireframe: true});
var mesh = new THREE.Mesh(geometry, material);
mesh.position.x = 100;
mesh.position.z = 100;
mesh.position.y = 10;
var slicer = new D3D.Slicer().setMesh(mesh);
var gcode = slicer.getGcode(printer);
doodleBox.print(gcode);
const settings = {
...defaultSettings.base,
...defaultSettings.material.pla,
...defaultSettings.printer.ultimaker2go,
...defaultSettings.quality.high
};
```
For more information see http://www.doodle3d.com/
const geometry = new THREE.TorusGeometry(20, 10, 30, 30);
const slicer = new SLICER.Slicer();
slicer.setGeometry(geometry);
const gcode = await slicer.slice(settings)
.progress(({ done, total, action }) => {
const percentage = `${(done / total * 100).toFixed()}%`
console.log(action, percentage);
});
```

/**
* @author aleeper / http://adamleeper.com/
* @author mrdoob / http://mrdoob.com/
* @author gero3 / https://github.com/gero3
*
* Description: A THREE loader for STL ASCII files, as created by Solidworks and other CAD programs.
*
* Supports both binary and ASCII encoded files, with automatic detection of type.
*
* Limitations:
* Binary decoding supports "Magics" color format (http://en.wikipedia.org/wiki/STL_(file_format)#Color_in_binary_STL).
* There is perhaps some question as to how valid it is to always assume little-endian-ness.
* ASCII decoding assumes file is UTF-8. Seems to work for the examples...
*
* Usage:
* var loader = new THREE.STLLoader();
* loader.load( './models/stl/slotted_disk.stl', function ( geometry ) {
* scene.add( new THREE.Mesh( geometry ) );
* });
*
* For binary STLs geometry might contain colors for vertices. To use it:
* // use the same code to load STL as above
* if (geometry.hasColors) {
* material = new THREE.MeshPhongMaterial({ opacity: geometry.alpha, vertexColors: THREE.VertexColors });
* } else { .... }
* var mesh = new THREE.Mesh( geometry, material );
