Detailed Description

implicit function for a sphere

vtkSphere computes the implicit function and/or gradient for a sphere. vtkSphere is a concrete implementation of vtkImplicitFunction. Additional methods are available for sphere-related computations, such as computing bounding spheres for a set of points, or set of spheres.

static vtkTypeBool vtkSphere::IsTypeOf ( const char * type )

static

virtual vtkTypeBool vtkSphere::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 vtkSphere* vtkSphere::SafeDownCast ( vtkObjectBase * o )

static

virtual vtkObjectBase* vtkSphere::NewInstanceInternal ( ) const

protectedvirtual

Reimplemented from vtkImplicitFunction.

vtkSphere* vtkSphere::NewInstance ( ) const

void vtkSphere::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

overridevirtual

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 vtkSphere* vtkSphere::New ( )

static

Construct sphere with center at (0,0,0) and radius=0.5.

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

overridevirtual

Evaluate function at position x-y-z and return value.

You should generally not call this method directly, you should use FunctionValue() instead. This method must be implemented by any derived class.

Implements vtkImplicitFunction.

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

overridevirtual

Evaluate sphere gradient.

Implements vtkImplicitFunction.

virtual void vtkSphere::SetRadius ( double )

virtual

Set / get the radius of the sphere.

The default is 0.5.

virtual double vtkSphere::GetRadius ( )

virtual

Set / get the radius of the sphere.

The default is 0.5.

virtual void vtkSphere::SetCenter	(	double	,
		double	,
		double
	)

virtual

Set / get the center of the sphere.

The default is (0,0,0).

virtual void vtkSphere::SetCenter ( double [3] )

virtual

Set / get the center of the sphere.

The default is (0,0,0).

virtual double* vtkSphere::GetCenter ( )

virtual

Set / get the center of the sphere.

The default is (0,0,0).

virtual void vtkSphere::GetCenter ( double data[3] )

virtual

Set / get the center of the sphere.

The default is (0,0,0).

static double vtkSphere::Evaluate	(	double	center[3],
		double	R,

	)

inlinestatic

Quick evaluation of the sphere equation ((x-x0)^2 + (y-y0)^2 + (z-z0)^2) - R^2.

static void vtkSphere::ComputeBoundingSphere	(	float *	pts,
		vtkIdType	numPts,
		float	sphere[4],
		vtkIdType	hints[2]
	)

static

Create a bounding sphere from a set of points.

The set of points is defined by an array of doubles, in the order of x-y-z (which repeats for each point). An optional hints array provides a guess for the initial bounding sphere; the two values in the hints array are the two points expected to be the furthest apart. The output sphere consists of a center (x-y-z) and a radius.

static

Create a bounding sphere from a set of spheres.

The set of input spheres is defined by an array of pointers to spheres. Each sphere is defined by the 4-tuple: center(x-y-z)+radius. An optional hints array provides a guess for the initial bounding sphere; the two values in the hints array are the two spheres expected to be the furthest apart. The output sphere consists of a center (x-y-z) and a radius.
