# 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 );
} );
```

/**
* 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:
* const loader = new 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 { .... }
* const 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:
*
* const mesh = new THREE.Mesh( geometry, material );
*
* For example:
*
* const materials = [];
* const nGeometryGroups = geometry.groups.length;
*
* const colorMap = ...; // Some logic to index colors.
*
* for (let i = 0; i < nGeometryGroups; i++) {
*
* const material = new THREE.MeshPhongMaterial({
* color: colorMap[i],
* wireframe: false
* });
*
* }
*
* materials.push(material);
* const mesh = new THREE.Mesh(geometry, materials);
