给定 3D 源文件， Qt3DRender::QSceneLoader 将试着剖析它并构建树为 Qt3DCore::QEntity 对象采用适当 Qt3DRender::QGeometryRenderer , Qt3DCore::QTransform and Qt3DRender::QMaterial components.
The loader will try to determine the best material to be used based on the properties of the model file. If you wish to use a custom material, you will have to traverse the tree and replace the default associated materials with yours.
顾名思义， Qt3DRender::QSceneLoader loads a complete scene subtree. If you wish to load a single piece of geometry, you should rather use the Qt3DRender::QMesh 代替。
Qt3DRender::QSceneLoader internally relies on the use of plugins to support a wide variety of 3D file formats. Here is a list of formats that are supported by Qt3D.
注意： this component shouldn't be shared among several Qt3DCore::QEntity instances. Undefined behavior will result.

The constructor creates an instance with the specified parent .
Returns a component matching componentType of a loaded entity with an objectName matching the entityName . If the entity has multiple matching components, the first match in the component list of the entity is returned. If there is no match, a null pointer is returned.
注意： 此函数可以被援引，通过元对象系统和从 QML。见 Q_INVOKABLE .
Returns a loaded entity with an
objectName
matching the
entityName
parameter. If multiple entities have the same name, it is undefined which one of them is returned, but it will always be the same one.
注意： 此函数可以被援引，通过元对象系统和从 QML。见 Q_INVOKABLE .
返回列表为
objectNames
of the loaded entities.
