Detailed Description

implicit function for a set of spheres

vtkSpheres computes the implicit function and function gradient for a set of spheres. The spheres are combined via a union operation (i.e., the minimum value from the evaluation of all spheres is taken).

The function value is the distance of a point to the closest sphere, with negative values interior to the spheres, positive outside the spheres, and distance=0 on the spheres surface. The function gradient is the sphere normal at the function value.

Standard methods for instantiation, type information, and printing.

◆ IsTypeOf()

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

static

◆ IsA()

virtual vtkTypeBool vtkSpheres::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.

◆ SafeDownCast()

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

static

◆ NewInstanceInternal()

virtual vtkObjectBase* vtkSpheres::NewInstanceInternal ( ) const

◆ NewInstance()

vtkSpheres* vtkSpheres::NewInstance ( ) const

◆ PrintSelf()

void vtkSpheres::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.

◆ EvaluateFunction() [1/4]

double vtkSpheres::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.

◆ EvaluateGradient()

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

overridevirtual

Evaluate spheres gradient.

Gradients point towards the outside of the spheres.

Implements vtkImplicitFunction.

◆ SetCenters()

virtual void vtkSpheres::SetCenters ( vtkPoints * )

virtual

Specify a list of points defining sphere centers.

◆ GetCenters()

virtual vtkPoints* vtkSpheres::GetCenters ( )

virtual

◆ SetRadii()

void vtkSpheres::SetRadii ( vtkDataArray * radii )

Specify a list of radii for the spheres.

There is a one-to-one correspondence between sphere points and sphere radii.

◆ GetRadii()

virtual vtkDataArray* vtkSpheres::GetRadii ( )

virtual

◆ GetNumberOfSpheres()

int vtkSpheres::GetNumberOfSpheres ( )

Return the number of spheres in the set of spheres.

◆ GetSphere() [1/2]

vtkSphere* vtkSpheres::GetSphere ( int i )

Create and return a pointer to a vtkSphere object at the ith position.

Asking for a sphere outside the allowable range returns nullptr. This method always returns the same object. Alternatively use GetSphere(int i, vtkSphere *sphere) to update a user supplied sphere.

◆ GetSphere() [2/2]

void vtkSpheres::GetSphere	(	int	i,
		vtkSphere *	sphere
	)

If i is within the allowable range, mutates the given sphere's Center and Radius to match the vtkSphere object at the ith position.

Does nothing if i is outside the allowable range.

◆ EvaluateFunction() [2/4]

virtual double vtkImplicitFunction::EvaluateFunction

Evaluate spheres equations.

Return largest value when evaluating all sphere equations.

◆ EvaluateFunction() [3/4]

virtual void vtkImplicitFunction::EvaluateFunction

Evaluate spheres equations.

Return largest value when evaluating all sphere equations.

◆ EvaluateFunction() [4/4]

virtual double vtkImplicitFunction::EvaluateFunction

inline

Evaluate spheres equations.

Return largest value when evaluating all sphere equations.
