/**
* Tessellates the famous Utah teapot database by Martin Newell into triangles.
*
* Parameters: size = 50, segments = 10, bottom = true, lid = true, body = true,
* fitLid = true, blinn = true
*
* size is a relative scale: I've scaled the teapot to fit vertically between -1 and 1.
* Think of it as a "radius".
* segments - number of line segments to subdivide each patch edge;
* 1 is possible but gives degenerates, so two is the real minimum.
* bottom - boolean, if true (default) then the bottom patches are added. Some consider
* adding the bottom heresy, so set this to "false" to adhere to the One True Way.
* lid - to remove the lid and look inside, set to true.
* body - to remove the body and leave the lid, set this and "bottom" to false.
* fitLid - the lid is a tad small in the original. This stretches it a bit so you can't
* see the teapot's insides through the gap.
* blinn - Jim Blinn scaled the original data vertically by dividing by about 1.3 to look
* nicer. If you want to see the original teapot, similar to the real-world model, set
* this to false. True by default.
* See http://en.wikipedia.org/wiki/File:Original_Utah_Teapot.jpg for the original
* real-world teapot (from http://en.wikipedia.org/wiki/Utah_teapot).
*
* Note that the bottom (the last four patches) is not flat - blame Frank Crow, not me.
*
* The teapot should normally be rendered as a double sided object, since for some
* patches both sides can be seen, e.g., the gap around the lid and inside the spout.
*
* Segments 'n' determines the number of triangles output.
* Total triangles = 32*2*n*n - 8*n [degenerates at the top and bottom cusps are deleted]
*
* size_factor # triangles
* 1 56
* 2 240
* 3 552
* 4 992
*
* 10 6320
* 20 25440
* 30 57360
*
* Code converted from my ancient SPD software, http://tog.acm.org/resources/SPD/
* Created for the Udacity course "Interactive Rendering", http://bit.ly/ericity
* YouTube video on teapot history: https://www.youtube.com/watch?v=DxMfblPzFNc
*
* See https://en.wikipedia.org/wiki/Utah_teapot for the history of the teapot

# Basis Universal GPU Texture Compression
Basis Universal is a "[supercompressed](http://gamma.cs.unc.edu/GST/gst.pdf)"
GPU texture and texture video compression system that outputs a highly
compressed intermediate file format (.basis) that can be quickly transcoded to
a wide variety of GPU texture compression formats.
[GitHub](https://github.com/BinomialLLC/basis_universal)
## Transcoders
Basis Universal texture data may be used in two different file formats:
`.basis` and `.ktx2`, where `ktx2` is a standardized wrapper around basis texture data.
For further documentation about the Basis compressor and transcoder, refer to
the [Basis GitHub repository](https://github.com/BinomialLLC/basis_universal).
The folder contains two files required for transcoding `.basis` or `.ktx2` textures:
* `basis_transcoder.js` — JavaScript wrapper for the WebAssembly transcoder.
* `basis_transcoder.wasm` — WebAssembly transcoder.
Both are dependencies of `KTX2Loader`:
```js
const ktx2Loader = new KTX2Loader();
ktx2Loader.setTranscoderPath( 'examples/jsm/libs/basis/' );
ktx2Loader.detectSupport( renderer );
ktx2Loader.load( 'diffuse.ktx2', function ( texture ) {
const material = new THREE.MeshStandardMaterial( { map: texture } );
}, function () {
console.log( 'onProgress' );
}, function ( e ) {
console.error( e );
} );
```

# Draco 3D Data Compression
Draco is an open-source library for compressing and decompressing 3D geometric meshes and point clouds. It is intended to improve the storage and transmission of 3D graphics.
[Website](https://google.github.io/draco/) | [GitHub](https://github.com/google/draco)
## Contents
This folder contains three utilities:
* `draco_decoder.js` — Emscripten-compiled decoder, compatible with any modern browser.
* `draco_decoder.wasm` — WebAssembly decoder, compatible with newer browsers and devices.
* `draco_wasm_wrapper.js` — JavaScript wrapper for the WASM decoder.
Each file is provided in two variations:
* **Default:** Latest stable builds, tracking the project's [master branch](https://github.com/google/draco).
* **glTF:** Builds targeted by the [glTF mesh compression extension](https://github.com/KhronosGroup/glTF/tree/master/extensions/2.0/Khronos/KHR_draco_mesh_compression), tracking the [corresponding Draco branch](https://github.com/google/draco/tree/gltf_2.0_draco_extension).
Either variation may be used with `DRACOLoader`:
```js
var dracoLoader = new DRACOLoader();
dracoLoader.setDecoderPath('path/to/decoders/');
dracoLoader.setDecoderConfig({type: 'js'}); // (Optional) Override detection of WASM support.
```
Further [documentation on GitHub](https://github.com/google/draco/tree/master/javascript/example#static-loading-javascript-decoder).

/**
* potpack - by [@mourner](https://github.com/mourner)
*
* A tiny JavaScript function for packing 2D rectangles into a near-square container,
* which is useful for generating CSS sprites and WebGL textures. Similar to
* [shelf-pack](https://github.com/mapbox/shelf-pack), but static (you can't add items
* once a layout is generated), and aims for maximal space utilization.
*
* A variation of algorithms used in [rectpack2D](https://github.com/TeamHypersomnia/rectpack2D)
* and [bin-pack](https://github.com/bryanburgers/bin-pack), which are in turn based
* on [this article by Blackpawn](http://blackpawn.com/texts/lightmaps/default.html).
