Detailed Description

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.
