## Detailed Description

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

## Property Documentation

### distanceThreshold : float

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

Access functions:

float | distanceThreshold() const
void | setDistanceThreshold(float distanceThreshold)

Notifier signal:

void | distanceThresholdChanged(float distanceThreshold)

### entity : Qt3DCore::QEntity*

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

Access functions:

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

Notifier signal:

void | entityChanged(Qt3DCore::QEntity *entity)
