详细描述

Select entities which are within a distance threshold of a target entity.

A Qt3DRender::QProximityFilter can be used to select entities to render when they are placed within a given distance threshold of another entity.

特性文档编制

distanceThreshold : float

Holds the distance to the target entity above which entities are filtered out.

访问函数：

float	distanceThreshold () const
void	setDistanceThreshold (float distanceThreshold )

通知程序信号：

void	distanceThresholdChanged (float distanceThreshold )

entity : Qt3DCore::QEntity *

Holds the entity against which we should compare the distance to.

访问函数：

Qt3DCore::QEntity *	entity () const
void	setEntity (Qt3DCore::QEntity * entity )

通知程序信号：

void	entityChanged (Qt3DCore::QEntity * entity )

成员函数文档编制

QProximityFilter:: QProximityFilter ( Qt3DCore::QNode * parent = nullptr)

Default constructs an instance of QProximityFilter.
