Detailed Description

implicit function for a bounding box

vtkBox computes the implicit function and/or gradient for a axis-aligned bounding box. (The superclasses transform can be used to modify this orientation.) Each side of the box is orthogonal to all other sides meeting along shared edges and all faces are orthogonal to the x-y-z coordinate axes. (If you wish to orient this box differently, recall that the superclass vtkImplicitFunction supports a transformation matrix.) vtkCube is a concrete implementation of vtkImplicitFunction.

static int vtkBox::IsTypeOf ( const char * type )

static

virtual int vtkBox::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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImplicitFunction.

static vtkBox* vtkBox::SafeDownCast ( vtkObjectBase * o )

static

virtual vtkObjectBase* vtkBox::NewInstanceInternal ( ) const

protectedvirtual

Reimplemented from vtkImplicitFunction.

vtkBox* vtkBox::NewInstance ( ) const

void vtkBox::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 vtkBox* vtkBox::New ( )

static

Construct box with center at (0,0,0) and each side of length 1.0.

double vtkBox::EvaluateFunction ( double x[3] )

virtual

Evaluate box defined by the two points (pMin,pMax).

Implements vtkImplicitFunction.

double vtkBox::EvaluateFunction	(	double	x,
		double	y,
		double	z
	)

inline

Evaluate box defined by the two points (pMin,pMax).

Definition at line 52 of file vtkBox.h.

void vtkBox::EvaluateGradient	(	double	x[3],
		double	n[3]
	)

virtual

Evaluate the gradient of the box.

Implements vtkImplicitFunction.

void vtkBox::SetXMin ( double p[3] )

Set / get the bounding box using various methods.

void vtkBox::GetBounds ( double bounds[6] )

double* vtkBox::GetBounds ( )

void vtkBox::AddBounds ( const double bounds[6] )

A special method that allows union set operation on bounding boxes. Start with a SetBounds(). Subsequent AddBounds() methods are union set operations on the original bounds. Retrieve the final bounds with a GetBounds() method.

static char vtkBox::IntersectBox	(	double	bounds[6],
		double	origin[3],
		double	dir[3],
		double	coord[3],
		double &	t
	)

static

Bounding box intersection modified from Graphics Gems Vol I. The method returns a non-zero value if the bounding box is hit. Origin[3] starts the ray, dir[3] is the vector components of the ray in the x-y-z directions, coord[3] is the location of hit, and t is the parametric coordinate along line. (Notes: the intersection ray dir[3] is NOT normalized. Valid intersections will only occur between 0<=t<=1.)

static int vtkBox::IntersectWithLine	(	const double	bounds[6],
		const double	p1[3],
		const double	p2[3],
		double &	t1,
		double &	t2,
		double	x1[3],
		double	x2[3],
		int &	plane1,
		int &	plane2
	)

static

Intersect a line with the box. Give the endpoints of the line in p1 and p2. The parameteric distances from p1 to the entry and exit points are returned in t1 and t2, where t1 and t2 are clamped to the range [0,1]. The entry and exit planes are returned in plane1 and plane2 where integers (0, 1, 2, 3, 4, 5) stand for the (xmin, xmax, ymin, ymax, zmin, zmax) planes respectively, and a value of -1 means that no intersection occurred. The actual intersection coordinates are stored in x1 and x2, which can be set to NULL of you do not need them to be returned. The function return value will be zero if the line is wholly outside of the box.
