class FOctreeNodeContext

Remarks

The context of an octree node, derived from the traversal of the tree.

Variables

	Name	Description
FBoxCenterAndEx...	Bounds	The bounds of the node.
float	ChildCenterOffset	The offset of the childrens' centers from the center of this node.
float	ChildExtent	The extent of the node's children.
uint32	InCullBits	Bits used for culling, semantics left up to the caller (except that it is always set to zero at the root).
uint32	OutCullBits	Bits used for culling, semantics left up to the caller (except that it is always set to zero at the root).

Constructors

	Name	Description
	FOctreeNodeContext()	Default constructor.
	FOctreeNodeContext ( const FBoxCenterAndExtent& InBound... )	Initialization constructor.
	FOctreeNodeContext ( uint32 InInCullBits, uint32 InOutCullBits )	Initialization constructor, this one is used when we done care about the box anymore
	FOctreeNodeContext ( const FBoxCenterAndExtent& InBound..., uint32 InInCullBits, uint32 InOutCullBits )	Initialization constructor.

Functions

	Name	Description
FOctreeNodeC...	GetChildContext ( FOctreeChildNodeRef ChildRef )	Child node initialization constructor.
void	GetChildContext ( FOctreeChildNodeRef ChildRef, FOctreeNodeContext*__restrict ... )	Construct a child context given the child ref. Optimized to remove all LHS.
FOctreeNodeC...	GetChildContext ( FOctreeChildNodeRef ChildRef, uint32 InInCullBits, uint32 InOutCullBits )	Child node initialization constructor.
FOctreeChild...	GetContainingChild ( const FBoxCenterAndExtent& Boundin... )	Determines which of the octree node's children contain the whole bounding box, if any.
FOctreeChild...	GetIntersectingChildren ( const FBoxCenterAndExtent& Boundin... )	Determines which of the octree node's children intersect with a bounding box.

Constants

Name	Description
LoosenessDenominator	The node bounds are expanded by their extent divided by LoosenessDenominator.
NegativeOneOneTable	The float table {-1.0f,1.0f}
