Member Data Documentation

unsigned char BIHNode::axis_

private

Value stores coordination of splitting area for inner nodes or depth for leaf nodes

• values 0,1,2 indicate inner node of tree and coordination of splitting area
• values 3 and greater indicate leaf node of tree and store depth of node (depth = axes_ - 3)

Definition at line 137 of file bih_node.hh.

double BIHNode::bound_

private

A non-leaf node has two childs (left and right). Their bounding boxes are created from the bounding box of parent so that in one direction the left child set max to its bound_ and the right child set its min to bound_. This way we can always repcreate bounding box of every node when traversing the tree from the root.

Definition at line 130 of file bih_node.hh.

private

child nodes indexes

Definition at line 123 of file bih_node.hh.

const unsigned char BIHNode::dimension = 3

static

count of dimensions

Definition at line 32 of file bih_node.hh.
