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.

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.
