Detailed Description

Perform calculations (mostly intersection calculations) on regions of a 3D binary spatial partitioning.

Given an axis aligned binary spatial partitioning described by a vtkBSPCuts object, perform intersection queries on various geometric entities with regions of the spatial partitioning.

Member Function Documentation

virtual const char* vtkBSPIntersections::GetClassName ( ) [virtual]

Reimplemented from vtkObject.

static int vtkBSPIntersections::IsTypeOf ( const char * name ) [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkObject.

virtual int vtkBSPIntersections::IsA ( const char * name ) [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkObject.

static vtkBSPIntersections* vtkBSPIntersections::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkObject.

void vtkBSPIntersections::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)			`[virtual]`

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

static vtkBSPIntersections* vtkBSPIntersections::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

void vtkBSPIntersections::SetCuts ( vtkBSPCuts * cuts )

Define the binary spatial partitioning.

virtual vtkBSPCuts* vtkBSPIntersections::GetCuts ( ) [virtual]

int vtkBSPIntersections::GetBounds ( double * bounds )

Get the bounds of the whole space (xmin, xmax, ymin, ymax, zmin, zmax) Return 0 if OK, 1 on error.

int vtkBSPIntersections::GetNumberOfRegions ( )

The number of regions in the binary spatial partitioning

int vtkBSPIntersections::GetRegionBounds	(	int	regionID,
		double	bounds[6]
	)

Get the spatial bounds of a particular region Return 0 if OK, 1 on error.

int vtkBSPIntersections::GetRegionDataBounds	(	int	regionID,
		double	bounds[6]
	)

Get the bounds of the data within the k-d tree region, possibly smaller than the bounds of the region. Return 0 if OK, 1 on error.

int vtkBSPIntersections::IntersectsBox	(	int	regionId,
		double *	x
	)

Determine whether a region of the spatial decomposition intersects an axis aligned box.

int vtkBSPIntersections::IntersectsBox	(	int	regionId,
		double	xmin,
		double	xmax,
		double	ymin,
		double	ymax,
		double	zmin,
		double	zmax
	)

Determine whether a region of the spatial decomposition intersects an axis aligned box.

int vtkBSPIntersections::IntersectsBox	(	int *	ids,
		int	len,
		double *	x
	)

Compute a list of the Ids of all regions that intersect the specified axis aligned box. Returns: the number of ids in the list.

int vtkBSPIntersections::IntersectsBox	(	int *	ids,
		int	len,
		double	x0,
		double	x1,
		double	y0,
		double	y1,
		double	z0,
		double	z1
	)

Compute a list of the Ids of all regions that intersect the specified axis aligned box. Returns: the number of ids in the list.

int vtkBSPIntersections::IntersectsSphere2	(	int	regionId,
		double	x,
		double	y,
		double	z,
		double	rSquared
	)

Determine whether a region of the spatial decomposition intersects a sphere, given the center of the sphere and the square of it's radius.

int vtkBSPIntersections::IntersectsSphere2	(	int *	ids,
		int	len,
		double	x,
		double	y,
		double	z,
		double	rSquared
	)

Compute a list of the Ids of all regions that intersect the specified sphere. The sphere is given by it's center and the square of it's radius. Returns: the number of ids in the list.

int vtkBSPIntersections::IntersectsCell	(	int	regionId,
		vtkCell *	cell,
		int	cellRegion = `-1`
	)

Determine whether a region of the spatial decomposition intersects the given cell. If you already know the region that the cell centroid lies in, provide that as the last argument to make the computation quicker.

int vtkBSPIntersections::IntersectsCell	(	int *	ids,
		int	len,
		vtkCell *	cell,
		int	cellRegion = `-1`
	)

Compute a list of the Ids of all regions that intersect the given cell. If you alrady know the region that the cell centroid lies in, provide that as the last argument to make the computation quicker. Returns the number of regions the cell intersects.

virtual int vtkBSPIntersections::GetComputeIntersectionsUsingDataBounds ( ) [virtual]

When computing the intersection of k-d tree regions with other objects, we use the spatial bounds of the region. To use the tighter bound of the bounding box of the data within the region, set this variable ON. (Specifying data bounds in the vtkBSPCuts object is optional. If data bounds were not specified, this option has no meaning.)
