Detailed Description#
The Qt3D run loop is controlled by the Qt3DRender::QAspectEngine.
QAbstractAspect subclasses can be registered by calling Qt3DCore::QAspectEngine::registerAspect() which will take care of registering the aspect and in turn that will call Qt3DCore::QAbstractAspect::onRegistered();
The simulation loop is launched as soon as a root QEntity is set on the QAspectEngine . This is followed by a call to onEngineStartup() on each aspect so that they can start their simulation work.
The simulation loop is stopped when the root entity is set to Qt3DCore::QEntityPtr(). This calls onEngineShutdown() on each aspect so that they can stop performing their simulation work.
Setting a new valid root entity would restart the simulation loop again.
- class PySide6.Qt3DCore.Qt3DCore.QAspectEngine([parent=None])#
- Parameters:
parent –
PySide6.QtCore.QObject
Constructs a new QAspectEngine with parent.
- PySide6.Qt3DCore.Qt3DCore.QAspectEngine.RunMode#
- PySide6.Qt3DCore.Qt3DCore.QAspectEngine.aspect(name)#
- Parameters:
name – str
- Return type:
Returns the asepect matching the name
Note
Required that the aspect was registered by name
- PySide6.Qt3DCore.Qt3DCore.QAspectEngine.aspects()#
- Return type:
.list of Qt3DCore.QAbstractAspect
Returns the aspects owned by the aspect engine.
- PySide6.Qt3DCore.Qt3DCore.QAspectEngine.executeCommand(command)#
- Parameters:
command – str
- Return type:
object
Executes the given command on aspect engine. Valid commands are:
“list aspects”
Returns the reply for the command.
- PySide6.Qt3DCore.Qt3DCore.QAspectEngine.lookupNode(id)#
- Parameters:
- Return type:
- PySide6.Qt3DCore.Qt3DCore.QAspectEngine.lookupNodes(ids)#
- Parameters:
ids – .list of Qt3DCore.QNodeId
- Return type:
.list of Qt3DCore.QNode
- PySide6.Qt3DCore.Qt3DCore.QAspectEngine.processFrame()#
If using the manual run mode, this function executes the jobs for each aspect. It is blocking and won’t return until all jobs have been completed.
If you are using the QRenderAspect,
- PySide6.Qt3DCore.Qt3DCore.QAspectEngine.registerAspect(aspect)#
- Parameters:
Registers a new aspect to the AspectManager. The QAspectEngine takes ownership of the aspect and will delete it when the aspect is unregistered.
- PySide6.Qt3DCore.Qt3DCore.QAspectEngine.registerAspect(name)
- Parameters:
name – str
Registers a new aspect to the AspectManager based on its name Uses the currently set aspect factory to create the actual aspect instance.
- PySide6.Qt3DCore.Qt3DCore.QAspectEngine.rootEntity()#
- Return type:
QSharedPointer
Returns the root entity of the aspect engine.

- PySide6.Qt3DCore.Qt3DCore.QAspectEngine.setRootEntity(root)#
- Parameters:
root –
QSharedPointer
Sets the root entity for the aspect engine.
See also
- PySide6.Qt3DCore.Qt3DCore.QAspectEngine.unregisterAspect(aspect)#
- Parameters:
Unregisters and deletes the given aspect.
- PySide6.Qt3DCore.Qt3DCore.QAspectEngine.unregisterAspect(name)
- Parameters:
name – str
Unregisters and deletes the aspect with the given name.
