Detailed Description

A subset of an octree node's children that intersect a bounding box.

Constructor & Destructor Documentation

FOctreeChildNodeSubset() [1/2]

FOctreeChildNodeSubset::FOctreeChildNodeSubset ( )

inline

Initializes the subset to be empty.

FOctreeChildNodeSubset() [2/2]

FOctreeChildNodeSubset::FOctreeChildNodeSubset ( FOctreeChildNodeRef  ChildRef )

inline

Initializes the subset to contain a single node.

Member Function Documentation

Contains()

bool FOctreeChildNodeSubset::Contains ( FOctreeChildNodeRef  ChildRef ) const

inline
