/**
* @class vtkImplicitHalo
* @brief implicit function for an halo
*
* vtkImplicitHalo evaluates to 1.0 for each position in the sphere of a
* given center and radius Radius*(1-FadeOut). It evaluates to 0.0 for each
* position out the sphere of a given Center and radius Radius. It fades out
* linearly from 1.0 to 0.0 for points in a radius from Radius*(1-FadeOut) to
* Radius.
* vtkImplicitHalo is a concrete implementation of vtkImplicitFunction.
* It is useful as an input to
* vtkSampleFunction to generate an 2D image of an halo. It is used this way by
* vtkShadowMapPass.
* @warning
* It does not implement the gradient.
