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 void vtkSphere::ComputeBoundingSphere ( float *  pts,
vtkIdType  numPts,
float  sphere[4],

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 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 void vtkSphere::ComputeBoundingSphere ( float **  spheres,
vtkIdType  numSpheres,
float  sphere[4],
vtkIdType  hints[2] 
)
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.

The output sphere consists of a center (x-y-z) and a radius.
