_BuildCollisionTree	(	AABBCollisionNode *	linear,
		const udword	box_id,
		udword &	current_id,
		const AABBTreeNode *	current_node
	)		[related]

Builds an implicit tree from a standard one. An implicit tree is a complete tree (2*N-1 nodes) whose negative box pointers and primitive pointers have been made implicit, hence packing 3 pointers in one.

Layout for implicit trees: Node:

• box
• data (32-bits value)

if data's LSB = 1 => remaining bits are a primitive pointer else remaining bits are a P-node pointer, and N = P + 1

Parameters:

linear	[in] base address of destination nodes
box_id	[in] index of destination node
current_id	[in] current running index
current_node	[in] current node from input tree
