+# bom-three.js (THREE.BOMLoader)
+A javascript library to import BOM (Binary Object/Material) files into three.js.  Loaded assets will be output as a THREE.Mesh
+consisting of THREE.BufferGeometry and an associated THREE.Material.  Multi-material assets may be split into multiple THREE.Mesh objects, per material.
+
+## Usage
+Include the loader library in your project:
+```html
+<script src="https://cdn.rawgit.com/NGenesis/bom-three.js/v0.3/examples/js/loaders/BOMLoader.min.js"></script>
+```
+
+Then create an instance of BOMLoader and specify the file path to load:
+### Javascript
+```javascript
+var filePath = 'https://example.com/path/to/file.bom';
+
+var loader = new THREE.BOMLoader();
+//loader.setDebug(true); // Output verbose debugging information (Disabled/false by default)
+//loader.setPerfTimer(true); // Output loader performance timer information (Disabled/false by default)
+loader.setTexturePath(filePath.split('/').slice(0, -1).join('/') + '/'); // Specify base texture path
+
+loader.load(filePath, function(obj) {
+	scene.add(obj); // Add object to scene once loaded.
+});
+```
