Member Function Documentation

float vtkSphere::EvaluateFunction float    x[3] [virtual]
 

Evaluate sphere equation ((x-x0)^2 + (y-y0)^2 + (z-z0)^2) - R^2.

Implements vtkImplicitFunction.

void vtkSphere::EvaluateGradient float    x[3],
float    n[3]
[virtual]
 

Evaluate sphere gradient.

Implements vtkImplicitFunction.

virtual const char* vtkSphere::GetClassName   [virtual]
 

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImplicitFunction.

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

Reimplemented from vtkImplicitFunction.

int vtkSphere::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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImplicitFunction.

vtkSphere* vtkSphere::New   [static]
 

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

Reimplemented from vtkObject.

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.

vtkSphere* vtkSphere::SafeDownCast vtkObject   o [static]
 

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImplicitFunction.

virtual void vtkSphere::SetCenter float   ,
float   ,
float   
[virtual]
 

Set / get the center of the sphere.

virtual void vtkSphere::SetRadius float    [virtual]
 

Set / get the radius of the sphere.
