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.

Member Function Documentation

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

Reimplemented from vtkImplicitFunction.

static int vtkBox::IsTypeOf ( const char * type ) [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 vtkImplicitFunction.

virtual int vtkBox::IsA ( const char * type ) [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 vtkImplicitFunction.

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

Reimplemented from vtkImplicitFunction.

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 vtkImplicitFunction.

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

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

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).
Reimplemented from vtkImplicitFunction.
Definition at line 50 of file vtkBox.h.
References vtkImplicitFunction::EvaluateFunction().

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

double n[3]

) [virtual]

Evaluate the gradient of the box.
Implements vtkImplicitFunction.

virtual void vtkBox::SetXMin ( double ,

double ,

double

) [virtual]

Set / get the bounding box using various methods.

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

Evaluate the gradient of the box.

virtual double* vtkBox::GetXMin ( ) [virtual]

Evaluate the gradient of the box.

virtual void vtkBox::GetXMin ( double & ,

double & ,

double &

) [virtual]

Evaluate the gradient of the box.

virtual void vtkBox::GetXMin ( double [3] ) [virtual]

Evaluate the gradient of the box.

virtual void vtkBox::SetXMax ( double ,

double ,

double

) [virtual]

Evaluate the gradient of the box.

virtual void vtkBox::SetXMax ( double [3] ) [virtual]

Evaluate the gradient of the box.

virtual double* vtkBox::GetXMax ( ) [virtual]

Evaluate the gradient of the box.

virtual void vtkBox::GetXMax ( double & ,

double & ,

double &

) [virtual]

Evaluate the gradient of the box.

virtual void vtkBox::GetXMax ( double [3] ) [virtual]

Evaluate the gradient of the box.

void vtkBox::SetBounds ( double xMin,

double xMax,

double yMin,

double yMax,

double zMin,

double zMax

)

Evaluate the gradient of the box.

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

Evaluate the gradient of the box.

void vtkBox::GetBounds ( double & xMin,

double & xMax,

double & yMin,

double & yMax,

double & zMin,

double & zMax

)

Evaluate the gradient of the box.

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

Evaluate the gradient of the box.

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.)
