Public Member Functions
	vtkOBBTree (IntPtr rawCppThis, bool callDisposalMethod, bool strong)
	Automatically generated constructor - called from generated code. DO NOT call directly.
	vtkOBBTree ()
	Construct with automatic computation of divisions, averaging 25 cells per octant.
override void	BuildLocator ()
	Satisfy locator's abstract interface, see vtkLocator.
void	ComputeOBB (vtkDataSet input, IntPtr corner, IntPtr max, IntPtr mid, IntPtr min, IntPtr size)
	Compute an OBB for the input dataset using the cells in the data. Return the corner point and the three axes defining the orientation of the OBB. Also return a sorted list of relative "sizes" of axes for comparison purposes.
override void	FindClosestPoint (IntPtr x, IntPtr closestPoint, ref int cellId, ref int subId, ref double dist2)
	Return the closest point and the cell which is closest to the point x. The closest point is somewhere on a cell, it need not be one of the vertices of the cell. This version takes in a vtkGenericCell to avoid allocating and deallocating the cell. This is much faster than the version which does not take a *cell, especially when this function is called many times in a row such as by a for loop, where the allocation and deallocation can be done only once outside the for loop. If a cell is found, "cell" contains the points and ptIds for the cell "cellId" upon exit.
override void	FindClosestPoint (IntPtr x, IntPtr closestPoint, vtkGenericCell cell, ref int cellId, ref int subId, ref double dist2)
	reimplemented from vtkAbstractCellLocator to support bad compilers
override int	FindClosestPointWithinRadius (IntPtr x, double radius, IntPtr closestPoint, ref int cellId, ref int subId, ref double dist2)

	reimplemented from vtkAbstractCellLocator to support bad compilers
override void	FreeSearchStructure ()
	Satisfy locator's abstract interface, see vtkLocator.
override void	GenerateRepresentation (int level, vtkPolyData pd)
	Create polygonal representation for OBB tree at specified level. If level < 0, then the leaf OBB nodes will be gathered. The aspect ratio (ar) and line diameter (d) are used to control the building of the representation. If a OBB node edge ratio's are greater than ar, then the dimension of the OBB is collapsed (OBB->plane->line). A "line" OBB will be represented either as two crossed polygons, or as a line, depending on the relative diameter of the OBB compared to the diameter (d).
int	InsideOrOutside (IntPtr point)
	Determine whether a point is inside or outside the data used to build this OBB tree. The data must be a closed surface vtkPolyData data set. The return value is +1 if outside, -1 if inside, and 0 if undecided.
override int	IntersectWithLine (IntPtr a0, IntPtr a1, double tol, ref double t, IntPtr x, IntPtr pcoords, ref int subId)
	reimplemented from vtkAbstractCellLocator to support bad compilers
override int	IntersectWithLine (IntPtr a0, IntPtr a1, double tol, ref double t, IntPtr x, IntPtr pcoords, ref int subId, ref int cellId)
	reimplemented from vtkAbstractCellLocator to support bad compilers
override int	IntersectWithLine (IntPtr a0, IntPtr a1, vtkPoints points, vtkIdList cellIds)
	Take the passed line segment and intersect it with the data set. This method assumes that the data set is a vtkPolyData that describes a closed surface, and the intersection points that are returned in 'points' alternate between entrance points and exit points. The return value of the function is 0 if no intersections were found, -1 if point 'a0' lies inside the closed surface, or +1 if point 'a0' lies outside the closed surface. Either 'points' or 'cellIds' can be set to NULL if you don't want to receive that information.
override int	IntersectWithLine (IntPtr a0, IntPtr a1, double tol, ref double t, IntPtr x, IntPtr pcoords, ref int subId, ref int cellId, vtkGenericCell cell)
	Return the first intersection of the specified line segment with the OBB tree, as well as information about the cell which the line segment intersected.

Detailed Description

vtkOBBTree - generate oriented bounding box (OBB) tree

Description vtkOBBTree is an object to generate oriented bounding box (OBB) trees. An oriented bounding box is a bounding box that does not necessarily line up along coordinate axes. The OBB tree is a hierarchical tree structure of such boxes, where deeper levels of OBB confine smaller regions of space.

To build the OBB, a recursive, top-down process is used. First, the root OBB is constructed by finding the mean and covariance matrix of the cells (and their points) that define the dataset. The eigenvectors of the covariance matrix are extracted, giving a set of three orthogonal vectors that define the tightest-fitting OBB. To create the two children OBB's, a split plane is found that (approximately) divides the number cells in half. These are then assigned to the children OBB's. This process then continues until the MaxLevel ivar limits the recursion, or no split plane can be found.

A good reference for OBB-trees is Gottschalk & Manocha in Proceedings of Siggraph `96.

Return the closest point and the cell which is closest to the point x. The closest point is somewhere on a cell, it need not be one of the vertices of the cell. This version takes in a vtkGenericCell to avoid allocating and deallocating the cell. This is much faster than the version which does not take a *cell, especially when this function is called many times in a row such as by a for loop, where the allocation and deallocation can be done only once outside the for loop. If a cell is found, "cell" contains the points and ptIds for the cell "cellId" upon exit.

virtual

Create polygonal representation for OBB tree at specified level. If level < 0, then the leaf OBB nodes will be gathered. The aspect ratio (ar) and line diameter (d) are used to control the building of the representation. If a OBB node edge ratio's are greater than ar, then the dimension of the OBB is collapsed (OBB->plane->line). A "line" OBB will be represented either as two crossed polygons, or as a line, depending on the relative diameter of the OBB compared to the diameter (d).

Determine whether a point is inside or outside the data used to build this OBB tree. The data must be a closed surface vtkPolyData data set. The return value is +1 if outside, -1 if inside, and 0 if undecided.
