BVNodeBase encodes the tree structure for BVH. More...

Inheritance diagram for fcl::BVNodeBase:

Public Member Functions
bool	isLeaf () const
	Whether current node is a leaf node (i.e. contains a primitive index.

int	primitiveId () const
	Return the primitive index. The index is referred to the original data (i.e. vertices or tri_indices) in BVHModel.

int	leftChild () const
	Return the index of the first child. The index is referred to the bounding volume array (i.e. bvs) in BVHModel.

int	rightChild () const
	Return the index of the second child. The index is referred to the bounding volume array (i.e. bvs) in BVHModel.

Public Attributes
int	first_child
	An index for first child node or primitive If the value is positive, it is the index of the first child bv node If the value is negative, it is -(primitive index + 1) Zero is not used.

int	first_primitive
	The start id the primitive belonging to the current node. The index is referred to the primitive_indices in BVHModel and from that we can obtain the primitive's index in original data indirectly.

int	num_primitives
	The number of primitives belonging to the current node.
