+ * Parameters: size = 50, segments = 10, bottom = true, lid = true, body = true,
+ *   fitLid = false, 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]

+# 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 `THREE.KTX2Loader` and `THREE.BasisTextureLoader`:
+
+```js
+var ktx2Loader = new THREE.KTX2Loader();
+ktx2Loader.setTranscoderPath( 'examples/js/libs/basis/' );
+ktx2Loader.detectSupport( renderer );
+ktx2Loader.load( 'diffuse.ktx2', function ( texture ) {
+
+	var 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 `THREE.DRACOLoader`:
+
+```js
+var dracoLoader = new THREE.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).

+ * Limitations: ASCII decoding assumes file is UTF-8.

+ * Usage:
+ *	var loader = new THREE.PLYLoader();
+ *	loader.load('./models/ply/ascii/dolphins.ply', function (geometry) {
+ *
+ *		scene.add( new THREE.Mesh( geometry ) );
+ *
+ *	} );
+ *
+ * If the PLY file uses non standard property names, they can be mapped while
+ * loading. For example, the following maps the properties
+ * “diffuse_(red|green|blue)” in the file to standard color names.
+ *
+ * loader.setPropertyNameMapping( {

+/**
+ * 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.
+ *
+ * The loader returns a non-indexed buffer geometry.
+ *
+ * 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.
+ *
+ * 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: true });
+ *  } else { .... }
+ *  var mesh = new THREE.Mesh( geometry, material );
+ *
+ * For ASCII STLs containing multiple solids, each solid is assigned to a different group.
+ * Groups can be used to assign a different color by defining an array of materials with the same length of
+ * geometry.groups and passing it to the Mesh constructor:
+ *
+ * var mesh = new THREE.Mesh( geometry, material );
+ *
+ * For example:
+ *
+ *  var materials = [];
+ *  var nGeometryGroups = geometry.groups.length;
+ *
+ *  var colorMap = ...; // Some logic to index colors.
+ *
+ *  for (var i = 0; i < nGeometryGroups; i++) {
+ *
+ *		var material = new THREE.MeshPhongMaterial({
+ *			color: colorMap[i],
+ *			wireframe: false
+ *		});
+ *
+ *  }
+ *
+ *  materials.push(material);
+ *  var mesh = new THREE.Mesh(geometry, materials);
