Member Function Documentation
◆ isLeaf()
| bool fcl::BVNodeBase::isLeaf | ( | ) | const |
Whether current node is a leaf node (i.e. contains a primitive index.
Definition at line 44 of file BV_node_base.cpp.
◆ leftChild()
| int fcl::BVNodeBase::leftChild | ( | ) | const |
Return the index of the first child. The index is referred to the bounding volume array (i.e. bvs) in BVHModel.
Definition at line 56 of file BV_node_base.cpp.
◆ primitiveId()
| int fcl::BVNodeBase::primitiveId | ( | ) | const |
Return the primitive index. The index is referred to the original data (i.e. vertices or tri_indices) in BVHModel.
Definition at line 50 of file BV_node_base.cpp.
◆ rightChild()
| int fcl::BVNodeBase::rightChild | ( | ) | const |
Return the index of the second child. The index is referred to the bounding volume array (i.e. bvs) in BVHModel.
Definition at line 62 of file BV_node_base.cpp.
Member Data Documentation
◆ first_child
| int fcl::BVNodeBase::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.
Definition at line 56 of file BV_node_base.h.
◆ first_primitive
| int fcl::BVNodeBase::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.
Definition at line 60 of file BV_node_base.h.
◆ num_primitives
| int fcl::BVNodeBase::num_primitives |
The number of primitives belonging to the current node.
