Constructor & Destructor Documentation

AABBTree::AABBTree ( )

Constructor.

Definition at line 373 of file OPC_AABBTree.cpp.

AABBTree::~AABBTree ( )

Destructor.

Definition at line 382 of file OPC_AABBTree.cpp.

Member Function Documentation

bool AABBTree::Build ( AABBTreeBuilder builder)

Builds a generic AABB tree from a tree builder.

Parameters
builder[in] the tree builder
Returns
true if success

Definition at line 405 of file OPC_AABBTree.cpp.

udword AABBTree::ComputeDepth ( ) const

Computes the depth of the tree. A well-balanced tree should have a log(n) depth. A degenerate tree O(n) depth.

Returns
depth of the tree

Definition at line 456 of file OPC_AABBTree.cpp.

inline_ const udword* Opcode::AABBTree::GetIndices ( ) const
inline

Catch the indices.

Definition at line 125 of file Opcode.h.

inline_ udword Opcode::AABBTree::GetNbNodes ( ) const
inline

Catch the number of nodes.

Definition at line 126 of file Opcode.h.

udword AABBTree::GetUsedBytes ( ) const

Computes the number of bytes used by the tree.

Returns
number of bytes used

Definition at line 556 of file OPC_AABBTree.cpp.

bool AABBTree::IsComplete ( ) const

Checks the tree is a complete tree or not. A complete tree is made of 2*N-1 nodes, where N is the number of primitives in the tree.

Returns
true for complete trees

Definition at line 570 of file OPC_AABBTree.cpp.

bool AABBTree::Refit ( AABBTreeBuilder builder)

Refits the tree in a top-down way.

Parameters
builder[in] the tree builder

Definition at line 501 of file OPC_AABBTree.cpp.

bool AABBTree::Refit2 ( AABBTreeBuilder builder)

Refits the tree in a bottom-up way.

Parameters
builder[in] the tree builder

Definition at line 514 of file OPC_AABBTree.cpp.

void AABBTree::Release ( )

Releases the tree.

Definition at line 392 of file OPC_AABBTree.cpp.

udword AABBTree::Walk ( WalkingCallback  callback,
void user_data 
) const

Walks the tree, calling the user back for each node.

Definition at line 466 of file OPC_AABBTree.cpp.
