Public Member Functions | |
BVNodeBase () | |
Default constructor. More... | |
bool | isLeaf () const |
Whether current node is a leaf node (i.e. contains a primitive index. More... | |
int | leftChild () const |
Return the index of the first child. The index is referred to the bounding volume array (i.e. bvs) in BVHModel. More... | |
bool | operator!= (const BVNodeBase &other) const |
Difference operator. More... | |
bool | operator== (const BVNodeBase &other) const |
Equality operator. More... | |
int | primitiveId () const |
Return the primitive index. The index is referred to the original data (i.e. vertices or tri_indices) in BVHModel. More... | |
int | rightChild () const |
Return the index of the second child. The index is referred to the bounding volume array (i.e. bvs) in BVHModel. More... | |
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. More... | |
unsigned 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. More... | |
unsigned int | num_primitives |
The number of primitives belonging to the current node. More... | |
