## 0.3.0

#### Enhancements

- Add an Object class: convenience methods to produce lines, spheres, tubes, and imported OBJ/MTL meshes, as well as a method to bring in THREE.Object3D's produced elsewhere with vanilla Three.js. Most of these are moveable, and have methods to move/rotate/rescale

- No need to call `tb.update()` after putting it in the custom layer's `render()` function.

#### Bug fixes

- Automatically adjust for viewport size (https://github.com/peterqliu/threebox/issues/43)

#### Deprecated (but still functional)
- `.setupDefaultLights()` has moved to an optional `defaultLights` parameter, in the third argument for Threebox().
- `tb.addAtCoordinate()` and `tb.moveToCoordinate()` have been deprecated. `tb.add(Object)` and `Object.setCoords()` replace them

# `threebox`

A three.js plugin for Mapbox GL JS, using the custom layer feature. Provides convenient methods to manage objects in lnglat coordinates, and to synchronize the map and scene cameras.

<img alt="threebox" src="docs/gallery.jpg">

### Compatibility/Dependencies

- Mapbox v.0.50.0 and later (for custom layer support)
- Three.r94 (already bundled into the Threebox build). If desired, other versions can be swapped in and rebuilt [here](https://github.com/peterqliu/threebox/blob/master/src/three.js), though compatibility is not guaranteed.

### Getting started

Download the bundle from [`dist/threebox.js`](dist/threebox.js) and add include it in a `<script>` tag on your page.

Several introductory examples are [here](https://github.com/peterqliu/threebox/tree/master/examples). To run them, create a `config.js` file with your Mapbox access token, alongside and in the format of [the template](https://github.com/peterqliu/threebox/blob/master/examples/config_template.js).

[Documentation lives here](docs/Threebox.md).

### Contributing

Build the library with `npm run build`, or `npm run dev` to rebuild continuously as you develop. Both commands will output a bundle in `/dist/threebox.js`.

Tests live [here](tests/) -- run `index.html` and check the console for test results.

![3D Symbol Layers](img/features-3D-symbols.png)

## `SymbolLayer3D`

The `SymbolLayer3D` object lets you load in a GeoJSON FeatureCollection of points and will automatically place 3D models at each point.

Create a 3D symbol layer using this syntax:
```
var symbols = threebox.addSymbolLayer({
  id:             'yourLayerName',
  source:         GeoJSON object | URL,
  modelName:      string | property | generator,
  modelDirectory: string | property | generator,
  rotation:       THREE.Euler | generator,
  scale:          number | property | generator,
  scaleWithMapProjection: boolean,
  key:            property | generator
});
```

### Examples

- [Static symbol layer](../examples/SymbolLayer3D.html)
- [Flocking demo showing fast updates and generator functions](../examples/flocking.html)

### Sources

Pass either an object that contains a GeoJSON `FeatureCollection` or a URL that points to a GeoJSON source as a parameter to `addSymbolLayer`. If you pass a URL, the GeoJSON source will be downloaded and parsed for you.

The `FeatureCollection` should contain a `features` array, and each feature should contain geometry of `type: Point`. `threebox` will place a 3D symbol at the specified longitude/latitude point for each feature.

### Scaling and units

The `scaleWithMapProjection` parameter can help when choosing units and scale factors for 3D symbols on a map. If set to `true` (default), the units of the 3D model file will be interpreted as **meters** at each feature's latitude. Because of distortion inherent in the Mercator projection, this means objects closer to the equator will be automatically scaled to appear smaller than objects closer to the poles. This lets you model your 3D symbols using real-world units and have them appear correctly at all latitudes.

If `scaleWithMapProjection` is set to `false`, the correspondence between your 3D symbol model units and map units can be defined however you see fit.

Units in 3D files coming from different sources tend be somewhat arbitrary and dependent on the context they are rendered into. In `threebox`, a line going from `{latitude: 0, longitude: 0}` to `{latitude: 0, longitude: 360}` (circumnavigating the world once at the equator) would measure 512 units long. Because of this, building- or vehicle-sized objects must generally be scaled down significantly to appear correctly if `scaleWithMapProject` is set to `false`.

### Models

`SymbolLayer3D` currently supports loading 3D models in the [.OBJ format](https://en.wikipedia.org/wiki/Wavefront_.obj_file) with materials specified in a corresponding [.MTL file](https://en.wikipedia.org/wiki/Wavefront_.obj_file#Material_template_library). These are common interchange formats that most 3D modeling programs can export. For proper rendering, it is important to ensure that the model's *normals are correctly facing outwards* and that all *faces are triangulated* (triangulating faces is an option when exporting in many programs). Simplified, low-polygon models work best; it may be necessary to model your 3D symbols specifically for use on a map just as you would design pixel-perfect icons in 2D.

Your `.obj` and `.mtl` files should share the same base file name and you should not include the file extension when specifying the `modelName` parameter. Both the geometry and material files will be loaded automatically based on the `modelName`. Specify the directory where your models are located using the `modelDirectory` parameter.


### Using `property` and `generator` rules for data-driven styling
Notice that some parameters can be set using an optional `property` or `generator` rule. These are two different ways of setting per-feature styles based on your data.

A `property` is an object of the form: `{ property: 'propertyName' }`. This lets you pull a value directly from the `properties` object of each GeoJSON `Feature`.

A `generator` is an object of the form: `{ generator: generatorFunction }`. The `generatorFunction` is a function taking two parameters (`feature`, `index`) that will be run for each GeoJSON `Feature`. This lets you perform custom transformations to turn feature properties into a value. For example:

```
var source = {
  type: "FeatureCollection",
  features: [
    {
      type: "Feature",
      properties: {
        heading: 30,
      },
      geometry: { type: "Point", coordinates: [-122, 37] }
    },
    ...
  ]
}

threebox.addSymbolLayer({
  rotation: { generator: (feature, index) => (
    new Three.Euler(0, 0, feature.properties['heading'] * Math.PI / 180), 'XYZ')
  ) },
  ...
});
```

_(This example uses [ES6 'arrow function'](https://medium.com/ecmascript-2015/arrow-functions-bb08eeb11667) notation for the generator function, but a regular function declaration or reference would work too)_

This generator converts the `heading` property from degrees to radians and uses it to rotate the 3D symbol about its z-axis. (_Note: There are many ways to describe rotations in 3D space with [Euler angles](https://threejs.org/docs/#Reference/Math/Euler) being perhaps the most intuitive and the standard for a `threebox` `SymbolLayer3D`. The exact function used here will depend on your needs._)

### Keys & updating data
To support **fast data updates** as well as **partial updates** of a 3D symbol layer, you can specify a `key` property that will be used to tie unique GeoJSON `Feature` objects to their corresponding object in the 3D scene graph. This way the 3D geometry needs only be created, destroyed, or updated when necessary.

It is best practice to specify the `key` property explicitly. If you don't, the array index of each feature is used as the key and you will not be able to perform reliable partial updates.

For example, assume each feature in your data has a unique `id` property and you create a new `SymbolLayer3D` with `key: { property: 'id' }`. You can then do the following to update your data:

```
symbols.updateSourceData({
  type: "FeatureCollection",
  features: [
    {
      type: "Feature",
      properties: {
        heading: 45,
        id: 'a_unique_feature'
      },
      geometry: {
        type: "Point",
        coordinates: [-123, 38]
      }
    }
  ]
});
```

This will update a single feature in the collection while leaving all the others alone. The pre-existing `rotation`, `scale`, and `modelName` `property` or `generator` rules will automatically be applied again to calculate new values on the updated features.

If this behavior is not desired, `updateSourceData` takes an optional second parameter, `absolute`, that if set to `true` will delete any features not included in the updated GeoJSON.

To remove a feature, use the `SymbolLayer3D.removeFeature` method and specify the `key` of the feature you want to remove.

## Background

Threebox works by adding a Three.js scene to Mapbox GL, via a custom layer. The custom layer API takes a fair amount of finessing to be useful, and Threebox tackles several hurdles to getting THREE and Mapbox to work together. 

<br>

## Setup

`var tb = new Threebox(map, mapboxGLContext[, options])`

Sets up a threebox scene inside a [Mapbox GL custom layer's onAdd function](https://www.mapbox.com/mapbox-gl-js/api/#customlayerinterface), which provides both inputs for this method. Automatically synchronizes the camera movement and events between Three.js and Mapbox GL JS. 

| option | required | default | type   | purpose                                                                                  |
|-----------|----------|---------|--------|----------------------------------------------------------------------------------------------|
| `defaultLights`    | no       | false      | boolean | Whether to add some default lighting to the scene. If no lighting added, most objects in the scene will render as black |
| `passiveRendering`     | no       | true   | boolean  | Color of line. Unlike other Threebox objects, this color will render on screen precisely as specified, regardless of scene lighting |
                                                              

`tb.update()`

Rerender the threebox scene. Fired in the custom layer's `render` function.


<br>

# Objects

Threebox offers convenience functions to construct meshes of various Three.js meshes, as well asl . Under the hood, they invoke a subclass of [THREE.Object3D](https://threejs.org/docs/#api/en/core/Object3D). 

Objects in Threebox fall under two broad varieties. *Static objects* don't move or change once they're placed, and used usually to display background or geographical features. They may have complex internal geometry, which are expressed primarily in lnglat coordinates. 

In contrast, *dynamic objects* can move around the map, positioned by a single lnglat point. Their internal geometries are produced mainly in local scene units, whether through external obj files, or these convenience methods below.

##Static objects

###Line 

`tb.line(options)`

Adds a line to the map, in full 3D space. Color renders independently of scene lighting. Internally, calls a [custom line shader](https://threejs.org/examples/?q=line#webgl_lines_fat).


| option | required | default | type   | purpose                                                                                  |
|-----------|----------|---------|--------|----------------------------------------------------------------------------------------------|
| `geometry`    | yes       | NA      | lineGeometry | Array of lnglat coordinates to draw the line |
| `color`     | no       | black   | color  | Color of line. Unlike other Threebox objects, this color will render on screen precisely as specified, regardless of scene lighting |
| `width`     | no       | 1   | number  | Line width. Unlike other Threebox objects, this width is in units of display pixels, rather than meters or scene units. |
| `opacity`     | no       | 1   | Number  | Line opacity |                                                                       


<br>

###Tube

`tb.tube(options)`

Extrude a tube along a specific lineGeometry, with an equilateral polygon as cross section. Internally uses a custom tube geometry generator.


| option | required | default | type   | description                                                                                  |
|-----------|----------|---------|--------|----------|
| `geometry`    | yes       | NA      | lineGeometry | Line coordinates forming the tube backbone |
| `radius`    | no       | 20      | number | Radius of the tube cross section, or half of tube width.|
| `sides`  | no       | 8       | number | Number of facets along the tube. The higher, the more closely the tube will approximate a smooth cylinder. |
| `material`     | no       | MeshLambertMaterial   | threeMaterial  | [THREE material](https://github.com/mrdoob/three.js/tree/master/src/materials) to use. Can be invoked with a text string, or a predefined material object via THREE itself.|   
| `color`     | no       | black   | color  | Tube color. Ignored if `material` is a predefined `THREE.Material` object.  |
| `opacity`     | no       | 1   | Number  | Tube opacity |                                                                                                                                                   


<br>
##Dynamic objects

<br>

###Sphere

`tb.sphere(options)`

Add a sphere to the map. Internally, calls `THREE.Mesh` with a `THREE.SphereGeometry`.


| option | required | default | type   | description                                                                                  |
|-----------|----------|---------|--------|-------|
| `radius`    | no       | 50      | number | Radius of sphere. |
| `units`    | no       | scene      | string ("scene" or "meters") | Units with which to interpret `radius`. If meters, Threebox will also rescale the object with changes in latitude, to appear to scale with objects and geography nearby.|
| sides  | no       | 8       | number | Number of width and height segments. The higher the number, the smoother the sphere. |
| color     | no       | black   | color  | Color of sphere.                                                                             
| `material`     | no       | MeshLambertMaterial   | threeMaterial  | [THREE material](https://github.com/mrdoob/three.js/tree/master/src/materials) to use. Can be invoked with a text string, or a predefined material object via THREE itself.|   

<br>

###External OBJ object

`threebox.loadObj(options, callback(obj))`

Loads an object via an external .obj and .mtl file. Note that unlike all the other object classes, this is asynchronous, and returns the object as an argument of the callback function. Internally, uses `THREE.OBJLoader` to fetch the .obj assets.


| option | required | default | type   | description                                                                                  |
|-----------|----------|---------|--------|------------|
| `obj`  | yes       | NA       | string | URL path to asset's .obj file |
| `mtl`  | yes       | NA       | string | URL path to asset's .mtl file |
| `units`    | no       | scene      | string ("scene" or "meters") | Units with which to interpret the object's vertices. If meters, Threebox will also rescale the object with changes in latitude, to appear to scale with objects and geography nearby.|
| `rotation`     | no       | 0   | rotationTransform  | Rotation of the object along the three axes, to align it to desired orientation before future rotations. Note that future rotations apply atop this transformation, and do not overwrite it. |
| `scale`     | no       | 1   | scaleTransform  | Scale of the object along the three axes, to size it appropriately before future transformations. Note that future scaling applies atop this transformation, rather than overwriting it.|
| `callback`     | yes       | NA   | function  | A function to run after the object loads. The first argument will be the successfully loaded object.

###Object3D

`threebox.Object3D(obj)`

Add a `THREE.Object3D` instantiated elsewhere in THREE, to empower it with Threebox methods below. Unnecessary for objects instantiated with any methods above.

| option | required | default | type   | description                                                                                  |
|-----------|----------|---------|--------|------------|
| `units`    | no       | scene      | string ("scene" or "meters") | Units with which to interpret the object's vertices. If meters, Threebox will also rescale the object with changes in latitude, to appear to scale with objects and geography nearby.|



###Shared methods between dynamic objects

`obj.setCoords(lnglat)`

Positions the object at the desired coordinate, and resizes it appropriately if it was instantiated with `units: "meters"`. Can be called before adding object to the map.

`obj.set(options)`

Broad method to update object's position, rotation, and scale. Check out the Threebox Types section below for details

Options

| option | required | default | type   | description                                                                                  |
|-----------|----------|---------|--------|------------|
| `coords`    | no       | NA      | `lnglat` | Position to which to move the object |
| `rotation`    | no       | NA      | `rotationTransform` | Rotation(s) to set the object, in units of degrees |
| `scale`    | no       | NA      | `scaleTransform` | Scale(s) to set the object, where 1 is the default scale |

`obj.followPath(options(, callback) )`

Translate object along a specified path. Optional callback function to execute when animation finishes

| option | required | default | type   | description                                                                                  |
|-----------|----------|---------|--------|------------|
| `path`    | yes       | NA      | lineGeometry | Path for the object to follow |
| `duration`    | no       | 1000      | number | Duration to travel the path, in milliseconds |
| `trackHeading`    | no       | true      | boolean | Rotate the object so that it stays aligned with the direction of travel, throughout the animation |



####`obj.stop()`

Stops all of object's current animations.

####`obj.duplicate()`

Returns a clone of the object. Greatly improves performance when handling many identical objects, by reusing materials and geometries.

<br>
##Utilities

`tb.projectToWorld(lnglat)`

Calculate the corresponding `Vector3` for a given lnglat.


`tb.unprojectFromWorld(Vector3)`

Calculate the corresponding lnglat for a given `Vector3`.


`tb.queryRenderedFeatures({x: number, y: number})`

Takes an input of `xy` as an object with values representing screen coordinates (as returned by mapboxgl mouse events as `e.point`). Returns an array of threebox objects at that screen position.

<br>

## Threebox types

<b>pointGeometry</b> `[longitude, latitude(, meters altitude)]`

An array of 2-3 numbers representing longitude, latitude, and optionally altitude (in meters). When altitude is omitted, it is assumed to be 0. When populating this from a GeoJSON Point, this array can be accessed at `point.geometry.coordinates`.  

While altitude is not standardized in the GeoJSON specification, Threebox will accept it as such to position objects along the z-axis.   

<br>

####lineGeometry

`[pointGeometry, pointGeometry ... pointGeometry]`

An array of at least two lnglat's, forming a line. When populating this from a GeoJSON Linestring, this array can be accessed at `linestring.geometry.coordinates`. 

<br>
####rotationTransform

`number` or `{x: number, y: number, z: number}`

Angle(s) in degrees to rotate object. Can be expressed as either an object or number. 

The object form takes three optional parameters along the three major axes: x is parallel to the equator, y parallel to longitudinal lines, and z perpendicular to the ground plane.

The number form rotates along the z axis, and equivalent to `{z: number}`.

<br>

####scaleTransform

`number ` or `{x: number, y: number, z: number}`

Amount to scale the object, where 1 is the default size. Can be expressed as either an object or number.

The three axes are identical to those of `rotationTransform`. However, expressing as number form scales all three axes by that amount.

####threeMaterial

`string` or instance of `THREE.Material()`

Denotes the material used for an object. This can usually be customized further with `color` and `opacity` parameters in the same 


Can be expressed as a string to the corresponding material type (e.g. `"MeshPhysicalMaterial"` for `THREE.MeshPhysicalMaterial()`), or a prebuilt THREE material directly.

##Using vanilla Three.js in Threebox

Threebox implements many small affordances to make mapping run in Three.js quickly and precisely on a global scale. Whenever possible, use threebox methods to add, change, manage, and remove elements of the scene. Otherwise, here are some best practices:

- Use `threebox.Object3D` to add custom objects to the scene
- If you must interact directly with the THREE scene, add all objects to `threebox.world`.
- `tb.projectToWorld` to convert lnglat to the corresponding `Vector3()`


#Performance considerations

- Use `obj.clone()` when adding many identical objects.

// a transform stream is a readable/writable stream where you do
// something with the data.  Sometimes it's called a "filter",
// but that's not a great name for it, since that implies a thing where
// some bits pass through, and others are simply ignored.  (That would
// be a valid example of a transform, of course.)
//
// While the output is causally related to the input, it's not a
// necessarily symmetric or synchronous transformation.  For example,
// a zlib stream might take multiple plain-text writes(), and then
// emit a single compressed chunk some time in the future.
//
// Here's how this works:
//
// The Transform stream has all the aspects of the readable and writable
// stream classes.  When you write(chunk), that calls _write(chunk,cb)
// internally, and returns false if there's a lot of pending writes
// buffered up.  When you call read(), that calls _read(n) until
// there's enough pending readable data buffered up.
//
// In a transform stream, the written data is placed in a buffer.  When
// _read(n) is called, it transforms the queued up data, calling the
// buffered _write cb's as it consumes chunks.  If consuming a single
// written chunk would result in multiple output chunks, then the first
// outputted bit calls the readcb, and subsequent chunks just go into
// the read buffer, and will cause it to emit 'readable' if necessary.
//
// This way, back-pressure is actually determined by the reading side,
// since _read has to be called to start processing a new chunk.  However,
// a pathological inflate type of transform can cause excessive buffering
// here.  For example, imagine a stream where every byte of input is
// interpreted as an integer from 0-255, and then results in that many
// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
// 1kb of data being output.  In this case, you could write a very small
// amount of input, and end up with a very large amount of output.  In
// such a pathological inflating mechanism, there'd be no way to tell
// the system to stop doing the transform.  A single 4MB write could
// cause the system to run out of memory.
//
// However, even in such a pathological case, only a single written chunk
// would be consumed, and then the rest would wait (un-transformed) until
// the results of the previous transformed chunk were consumed.

                (plus anything preceding it).

                    /^(?:[^\s]*\s*\bat\s+)/

                Second captures function call description (optional). This is
                not necessarily a valid JS function name, but just what the
                stack trace is using to represent a function call. It may look
                like `<anonymous>` or 'Test.bound [as run]'.

                For our purposes, we assume that, if there is a function
                name, it's everything leading up to the first open
                parentheses (trimmed) before our pathname.

                    /(?:(.*)\s+\()?/

                Last part captures file path plus line no (and optional
                column no).

                    /((?:\/|[a-zA-Z]:\\)[^:\)]+:(\d+)(?::(\d+))?)/
            */
            var re = /^(?:[^\s]*\s*\bat\s+)(?:(.*)\s+\()?((?:\/|[a-zA-Z]:\\)[^:\)]+:(\d+)(?::(\d+))?)/
            var m = re.exec(err[i]);

            if (!m) {
                continue;
            }

            var callDescription = m[1] || '<anonymous>';
            var filePath = m[2];

            if (filePath.slice(0, dir.length) === dir) {
                continue;
            }

            // Function call description may not (just) be a function name.
            // Try to extract function name by looking at first "word" only.
            res.functionName = callDescription.split(/\s+/)[0]
            res.file = filePath;
            res.line = Number(m[3]);
            if (m[4]) res.column = Number(m[4]);

            res.at = callDescription + ' (' + filePath + ')';
            break;
        }
    }
