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.
| 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.
