vtkSphere Class Reference
#include <vtkSphere.h>
Detailed Description
implicit function for a spherevtkSphere 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.

| virtual const char* vtkSphere::GetClassName | ( | ) | [virtual] |
Reimplemented from vtkImplicitFunction.
| static int vtkSphere::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 vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkImplicitFunction.
| virtual int 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.

| void vtkSphere::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 vtkSphere* vtkSphere::New | ( | ) | [static] |
Construct sphere with center at (0,0,0) and radius=0.5.
Reimplemented from vtkObject.
| double vtkSphere::EvaluateFunction | ( | double | x[3] | ) | [virtual] |
Evaluate sphere equation ((x-x0)^2 + (y-y0)^2 + (z-z0)^2) - R^2.
Implements vtkImplicitFunction.
| double vtkSphere::EvaluateFunction | ( | double | x, | |
| double | y, | |||
| double | z | |||
| ) | [inline] |
Evaluate sphere equation ((x-x0)^2 + (y-y0)^2 + (z-z0)^2) - R^2.

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

| 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.

| float | sphere[4], | |||

| ) | [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.
