Qt3DRender.QSceneLoader ¶

概要 ¶

详细描述 ¶

Given a 3D source file, the QSceneLoader will try to parse it and build a tree of QEntity objects with proper QGeometryRenderer , QTransform and 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.

As the name implies, QSceneLoader loads a complete scene subtree. If you wish to load a single piece of geometry, you should rather use the QMesh 代替。

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 QEntity instances. Undefined behavior will result.

PySide2.Qt3DRender.Qt3DRender.QSceneLoader. component ( entityName , componentType ) ¶

参数

• entityName – unicode

• componentType – ComponentType

返回类型

QComponent

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.

PySide2.Qt3DRender.Qt3DRender.QSceneLoader. entity ( entityName ) ¶

参数

entityName – unicode

返回类型

QEntity

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.

PySide2.Qt3DRender.Qt3DRender.QSceneLoader. entityNames ( ) ¶

返回类型

字符串列表

返回列表为 objectNames of the loaded entities.
