Detailed Description
template<class T>
class pcl::QuadTree< T >::Node
Definition at line 158 of file QuadTree.h.
Constructor & Destructor Documentation
◆ Node() [1/2]
|
default |
Default constructor. Constructs an uninitialized quadtree node.
◆ Node() [2/2]
|
inline |
Constructs a quadtree node for the specified rectangular region r.
Definition at line 178 of file QuadTree.h.
Member Function Documentation
◆ Includes() [1/2]
|
inline |
Returns true iff the rectangular region represented by this node includes the specified point p in the plane.
Definition at line 221 of file QuadTree.h.
References pcl::QuadTree< T >::Node::Includes(), pcl::GenericPoint< T >::x, and pcl::GenericPoint< T >::y.
◆ Includes() [2/2]
|
inline |
Returns true iff the rectangular region represented by this node includes a point in the plane specified by its coordinates x, y.
Definition at line 211 of file QuadTree.h.
References pcl::QuadTree< T >::Node::rect, pcl::GenericRectangle< T >::x0, pcl::GenericRectangle< T >::x1, pcl::GenericRectangle< T >::y0, and pcl::GenericRectangle< T >::y1.
Referenced by pcl::QuadTree< T >::Node::Includes(), and pcl::QuadTree< T >::SplitAt().
◆ Intersects()
|
inline |
Returns true iff the rectangular region represented by this node intersects the specified rectangle r.
Definition at line 201 of file QuadTree.h.
References pcl::QuadTree< T >::Node::rect, pcl::GenericRectangle< T >::x0, pcl::GenericRectangle< T >::x1, pcl::GenericRectangle< T >::y0, and pcl::GenericRectangle< T >::y1.
◆ IsLeaf()
|
inline |
Returns true iff this is a leaf quadtree node. A leaf node does not contain child nodes, that is, there is no further subdivision of the domain space beyond a leaf quadtree node.
In a healthy quadtree (as any QuadTree structure should be under normal working conditions), you can expect any leaf node to be an instance of QuadTree::LeafNode containing a nonempty list of points.

◆ NERect()
|
inline |
Returns the Northeast (top right) splitting rectangle for this node.
Definition at line 237 of file QuadTree.h.
References pcl::GenericRectangle< T >::CenterRight(), pcl::GenericRectangle< T >::CenterTop(), and pcl::QuadTree< T >::Node::rect.
◆ NWRect()
|
inline |
Returns the Northwest (top left) splitting rectangle for this node.
Definition at line 229 of file QuadTree.h.
References pcl::GenericRectangle< T >::Center(), pcl::QuadTree< T >::Node::rect, and pcl::GenericRectangle< T >::TopLeft().
◆ SERect()
|
inline |
Returns the Southeast (bottom right) splitting rectangle for this node.
Definition at line 254 of file QuadTree.h.
References pcl::GenericRectangle< T >::BottomRight(), pcl::GenericRectangle< T >::Center(), and pcl::QuadTree< T >::Node::rect.
◆ SWRect()
|
inline |
Returns the Southwest (bottom left) splitting rectangle for this node.
