/**
|
||||
* 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);
