| OBBTreeNode (const OBBTreeNodeImpl &impl) | |
| const OrientedBoundingBox & | getBounds () const |
| Get the OrientedBoundingBox which encloses all triangles in this node or its children. | |

| Get whether this is a leaf node. | |
| const OBBTreeNode | getFirstChildNode () const |
| Get the first child node. | |
| const OBBTreeNode | getSecondChildNode () const |
| Get the second child node. | |

This class represents a node in the Oriented Bounding Box Tree for a TriangleMesh.
Each node has an OrientedBoundingBox that fully encloses all triangles contained within it or its children. This is a binary tree: each non-leaf node has two children. Triangles are stored only in the leaf nodes.
| OBBTreeNode | ( | const OBBTreeNodeImpl & | impl | ) |
| const OrientedBoundingBox& getBounds | ( | ) | const |
Get the OrientedBoundingBox which encloses all triangles in this node or its children.
| const OBBTreeNode getFirstChildNode | ( | ) | const |
Get the first child node.
Calling this on a leaf node will produce an exception.
| int getNumTriangles | ( | ) | const |
Get the number of triangles inside this node.
If this is not a leaf node, this is the total number of triangles contained by all children of this node.
| const OBBTreeNode getSecondChildNode | ( | ) | const |
Get the second child node.
Calling this on a leaf node will produce an exception.
| const std::vector<int>& getTriangles | ( | ) | const |
Get the indices of all triangles contained in this node.
Calling this on a non-leaf node will produce an exception.
| bool isLeafNode | ( | ) | const |
Get whether this is a leaf node.
