特性

boundingVolumesEnabled : bool

公共函数

	QCoreSettings (Qt3DCore::QNode * parent = nullptr)
bool	boundingVolumesEnabled () const

公共槽

void	setBoundingVolumesEnabled (bool boundingVolumesEnabled )

信号

void	boundingVolumesEnabledChanged (bool boundingVolumesEnabled )

详细描述

The QCoreSettings component should be set as a component of the scene root entity (although it could be anywhere in the scene graph). There should be a single instance.

它可以用于控制 Qt 3D 的某些行为。

特性文档编制

boundingVolumesEnabled : bool

Holds whether bounding volumes handling is enabled. This is true by default. Disabling this allows to reduce the amount of computations performed each frame. If you are using picking or frustum culling you should keep this enabled (even when providing explicit bounding volumes sizes using QBoundingVolume ).

访问函数：

bool	boundingVolumesEnabled () const
void	setBoundingVolumesEnabled (bool boundingVolumesEnabled )

通知程序信号：

void	boundingVolumesEnabledChanged (bool boundingVolumesEnabled )

`[explicit]` QCoreSettings:: QCoreSettings ( Qt3DCore::QNode * parent = nullptr)
