-# Doodle3D Slicer
-This document explains how the slice process works.
-
-In this slicer Z is the "up" vector.
-
-Requisites
- - 2D Vector math
- - 3D Vector math
- - 2D Boolean operations (union, difference)
- - 2D Path offsetting
-
-### Step 0: Preparation
-The first step is to prepare the data for slicing. Most of the model data is mapped into `typed arrays`. This way they can be send to the worker very efficiently (due to the transferable nature of typed arrays).
-```
-Vertices: Float32Array
-Faces: Uint32Array
-ObjectIndexes: UInt8Array
-OpenObjectIndexes: [...Int]
-Settings:
-  startCode: String
-  endcode: String
-  dimensions:
-    x: Number
-    y: Number
-    z: Number
-  heatedBed: Bool
-  nozzleDiameter: Number
-  filamentThickness: Number
-  temperature: Number
-  bedTemperature: Number
-  layerHeight: Number
-  combing: Bool
-  thickness:
-    top: Number
-    bottom: Number
-    shell: Number
-  retraction:
-    enabled: Bool
-    amount: Number
-    speed: Number
-    minDistance: Number
-  travel:
-    speed: Number
-  support:
-    enabled: Bool
-    minArea: Number
-    distanceY: Number
-    density: Number
-    margin: Number
-    flowRate: Number
-    speed: Number
-  innerShell:
-    flowRate: Number
-    speed: Number
-  outerShell:
-    flowRate: Number
-    speed: Number
-  innerInfill:
-    flowRate: Number
-    speed: Number
-    density: Number
-  outerInfill:
-    flowRate: Number
-    speed: Number
-  brim:
-    size: Number
-    flowRate: Number
-    speed: Number
-  firstLayer:
-    flowRate: Number
-    speed: Number
-```
- - Vertices: List of points in 3d
- - Faces: Indexes refering to points in the vertices list that make a triangular surface
- - ObjectIndexes: Describes of what object each face is part of (important for the generating of 2d shapes)
- - OpenObjectIndexes: Determines weather a object is open or closed (important for the generating of 2d shapes)
- - Settings: object containing all the settings for slicing. We go in depth in this object when it's needed
-
-### Step 1: Creating lines
-In this we take the 3d model and look at each surface to extract all individual lines. Note some lines are part of multiple surfaces. In addition we also add some additional data to each line, like the surfaces it is part of we'll also store the 2d normal.
-
-```
-function calculateNormal(vertices, a, b, c) {
-  a = getVertex(vertices, a);
-  b = getVertex(vertices, b);
-  c = getVertex(vertices, c);
-
-  const cb = vector3.subtract(c, b);
-  const ab = vector3.subtract(a, b);
-  const normal = vector3.normalize(vector3.cross(cb, ab));
-
-  return normal;
-}
-```
-
-In order to extract all unique lines from the model we'll loop through each face of the model.
-
-### Step 2: Calculate Layers Intersections
-This is a fairly straight forward step. We take the lines and calculate on what layers that line will be intersecting. Additinally we calculate the coordinates where the line intersects each layer.
-
-### Step 3: Intersections To Shapes
-### Step 4: Shapes To Slices
-### Step 5: Generate Inner Lines
-### Step 6: Generate Outlines
-### Step 7: Generate Infills
-### Step 8: Generate Support
-### Step 9: AddBrim
-
-```
-let {
-  brim: { size: brimSize },
-  nozzleDiameter
-} = settings;
-
-nozzleDiameter /= PRECISION;
-brimSize /= PRECISION;
-const nozzleRadius = nozzleDiameter / 2;
-
-const [firstLayer] = slices;
-
-const brim = firstLayer.parts.reduce((brim, { shape }) => (
-  brim.join(shape.offset(nozzleRadius, {
-    endType: shape.closed ? 'etClosedPolygon' : 'etOpenRound'
-  }))
-), new Shape([], true)).simplify('pftNonZero');
-
-firstLayer.brim = new Shape([], true);
-
-for (let offset = 0; offset < brimSize; offset += nozzleDiameter) {
-  const brimPart = brim.offset(offset, OFFSET_OPTIONS);
-  firstLayer.brim = firstLayer.brim.join(brimPart);
-}

-import * as THREE from 'three';
-import { defaultSettings, sliceGeometry } from 'Doodle3D/Doodle3D-Slicer';
+import THREE from 'three.js';
+import * as SLICER from 'doodle3d-slicer';

+  ...SLICER.printerSettings['ultimaker2go'],
+  ...SLICER.userSettings
+});

-const geometry = new THREE.TorusGeometry(20, 10, 30, 30).clone();
+const geometry = new THREE.TorusGeometry(20, 10, 30, 30);

-# API
-
-**Settings**
-```javascript
-import { defaultSettings } from 'Doodle3D/Doodle3D-Slicer';
-
-const settings = {
-  ...defaultSettings.default,
-  ...defaultSettings.material.pla,
-  ...defaultSettings.printer.ultimaker2go,
-  ...defaultSettings.quality.high
-};
-```
-Create settings object to be used by the slicer
-
-**Slice Mesh**
-```javascript
-import { sliceMesh } from 'Doodle3D/Doodle3D-Slicer';
-
-GCode: String = sliceMesh(settings: Object, mesh: THREE.Mesh, [sync: Boolean = false, onProgress: Func ])
-```
-Slice function that accepts Meshes
-  - Settings: settings object (see [settings](#settings))
-  - Mesh: THREE.Mesh instance that contains the geometry
-  - Sync: determines if the slicing progress will be sync (blocking) or async (non-blocking). A webworker is used to slice async
-  - onProgress: progress callback
-
-**Slice Geometry**
-```javascript
-import { sliceGeometry } from 'Doodle3D/Doodle3D-Slicer';
-
-GCode: String = sliceGeometry(settings: Object, geometry: THREE.Geometry | THREE.BufferGeometry, [matrix: THREE.Matrix, sync: Boolean = false, onProgress: Func ])
-```
-
-Slice function that accepts Geometry
-  - Settings: settings object (see [settings](#settings))
-  - Geometry: THREE.Geometry instance
-  - matrix: matrix that can control the scale, rotation and position of the model
-  - Sync: determines if the slicing progress will be sync (blocking) or async (non-blocking). A webworker is used to slice async
-  - onProgress: progress callback
