For example, ``\n * is an element that renders a sphere on the screen and is backed by the\n * [`Sphere`](./Sphere) class which extends from `Element3D`.\n *\n * All Nodes must be a child of a [`Scene`](/api/core/Scene) node (``\n * elements) or another `Element3D` (or anything that extends from `Element3D`).\n * If a `` element is a child of anything else, it will not do\n * anything currently.\n *\n * The `Element3D` class (backing `` elements) is useful for the following:\n *\n * - Transform a parent node in 3D space, and it will transform all its\n * children and grandchildren along with it. For example, if you scale a\n * parent `Element3D`, then all its children are scaled along too.\n * - Transform child Nodes relative to their parent.\n * - Render traditional HTML content by placing any regular HTML elements as\n * children of a `` element. See the next example.\n * - Extend the `Element3D` class to make new types of 3D elements relying on the basic\n * features that `Element3D` provides. Other classes that extend from `Element3D` may, for\n * example, create [layouts](/examples/autolayout-declarative), or render\n * [WebGL content](/examples/hello-world/).\n *\n * ## Example\n *\n * The following example shows traditional HTML content inside a 3D scene, as\n * well as the concept of a hierarchy of nodes called a \"scene graph\".\n *\n * Regular HTML content is places in each `` element. CSS is applied\n * to the nodes to give them rounded borders. Standard\n * [`` elements](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/img)\n * are used display the sun images.\n *\n * We create a hierarchy of nodes. We give each node further down in the\n * hiearchy a smaller size. We use `align` and `mount-point` attributes to\n * align Nodes to one corner of their parent. `align` controls where a node is\n * mounted relative to their parent, and `mount-point` specifies the point in\n * the child that is aligned in the parent. See the [alignment guide](TODO)\n * for how that works.\n *\n * Each node has the same amount of rotation directly applied to it. Due to the\n * hiearchy, the rotations add up. The parent most node has the least\n * amount of rotation, and the child-most nodes have the most rotation and also\n * are more displaced due to rotation of their parents. See the [scene graph\n * guide](TODO) for details on how the hierarchy works.\n *\n * Finally, we listen to mouse or finger movement events in order to apply a\n * rotation to the root node based on the current mouse or finger position.\n * See the [events guide](TODO) for how the event system works.\n *\n * \n *\n * @extends SharedAPI\n */\nexport {Element3D}\n@element('lume-element3d', autoDefineElements)\nclass Element3D extends SharedAPI {\n\toverride readonly hasShadow: boolean = false\n\n\t/**\n\t * @property {true} isElement3D -\n\t *\n\t * *readonly*\n\t *\n\t * Always `true` for things that are or inherit from `Element3D`.\n\t */\n\toverride readonly isElement3D = true\n\n\t/**\n\t * @property {boolean} visible -\n\t *\n\t * *attribute*\n\t *\n\t * Default: `true`\n\t *\n\t * Whether or not the node will be\n\t * visible (if it renders anything).

function (geometry) {\n *\n *\t\tscene.add( new THREE.Mesh( geometry ) );\n *\n *\t} );\n *\n * If the PLY file uses non standard property names, they can be mapped while\n * loading. For example, the following maps the properties\n * \u201Cdiffuse_(red|green|blue)\u201D in the file to standard color names.\n *\n * loader.setPropertyNameMapping( {\n *\tdiffuse_red: 'red',\n *\tdiffuse_green: 'green',\n *\tdiffuse_blue: 'blue'\n * } );\n *\n * Custom properties outside of the defaults for position, uv, normal\n * and color attributes can be added using the setCustomPropertyNameMapping method.\n * For example, the following maps the element properties \u201Ccustom_property_a\u201D\n * and \u201Ccustom_property_b\u201D to an attribute \u201CcustomAttribute\u201D with an item size of 2.\n * Attribute item sizes are set from the number of element properties in the property array.\n *\n * loader.setCustomPropertyNameMapping( {\n *\tcustomAttribute: ['custom_property_a', 'custom_property_b'],\n * } );\n *\n */\n\nconst _color = new Color();\n\nclass PLYLoader extends Loader {\n\n\tconstructor( manager ) {\n\n\t\tsuper( manager );\n\n\t\tthis.propertyNameMapping = {};\n\t\tthis.customPropertyMapping = {};\n\n\t}\n\n\tload( url, onLoad, onProgress, onError ) {\n\n\t\tconst scope = this;\n\n\t\tconst loader = new FileLoader( this.manager );\n\t\tloader.setPath( this.path );\n\t\tloader.setResponseType( 'arraybuffer' );\n\t\tloader.setRequestHeader( this.requestHeader );\n\t\tloader.setWithCredentials( this.withCredentials );\n\t\tloader.load( url, function ( text ) {\n\n\t\t\ttry {\n\n\t\t\t\tonLoad( scope.parse( text ) );\n\n\t\t\t} catch ( e ) {\n\n\t\t\t\tif ( onError ) {\n\n\t\t\t\t\tonError( e );\n\n\t\t\t\t} else {\n\n\t\t\t\t\tconsole.error( e );\n\n\t\t\t\t}\n\n\t\t\t\tscope.manager.itemError( url );\n\n\t\t\t}\n\n\t\t}, onProgress, onError );\n\n\t}\n\n\tsetPropertyNameMapping( mapping ) {\n\n\t\tthis.propertyNameMapping = mapping;\n\n\t}\n\n\tsetCustomPropertyNameMapping( mapping ) {\n\n\t\tthis.customPropertyMapping = mapping;\n\n\t}\n\n\tparse( data ) {\n\n\t\tfunction parseHeader( data, headerLength = 0 ) {\n\n\t\t\tconst patternHeader = /^ply([\\s\\S]*)end_header(\\r\\n|\\r|\\n)/;\n\t\t\tlet headerText = '';\n\t\t\tconst result = patternHeader.exec( data );\n\n\t\t\tif ( result !== null ) {\n\n\t\t\t\theaderText = result[ 1 ];\n\n\t\t\t}\n\n\t\t\tconst header = {\n\t\t\t\tcomments: [],\n\t\t\t\telements: [],\n\t\t\t\theaderLength: headerLength,\n\t\t\t\tobjInfo: ''\n\t\t\t};\n\n\t\t\tconst lines = headerText.split( /\\r\\n|\\r|\\n/ );\n\t\t\tlet currentElement;\n\n\t\t\tfunction make_ply_element_property( propertValues, propertyNameMapping ) {\n\n\t\t\t\tconst property = { type: propertValues[ 0 ] };\n\n\t\t\t\tif ( property.type === 'list' ) {\n\n\t\t\t\t\tproperty.name = propertValues[ 3 ];\n\t\t\t\t\tproperty.countType = propertValues[ 1 ];\n\t\t\t\t\tproperty.itemType = propertValues[ 2 ];\n\n\t\t\t\t} else {\n\n\t\t\t\t\tproperty.name = propertValues[ 1 ];\n\n\t\t\t\t}\n\n\t\t\t\tif ( property.name in propertyNameMapping ) {\n\n\t\t\t\t\tproperty.name = propertyNameMapping[ property.name ];\n\n\t\t\t\t}\n\n\t\t\t\treturn property;\n\n\t\t\t}\n\n\t\t\tfor ( let i = 0;
