[vtkusers] How implement other ligtning model in VTK

[Robert Belleman]

Robert,

Lighting and rendering is done by OpenGL, not by Vtk.
If you want to implement a new lighting model you would
have to do this in OpenGL. For details on the lighting
model used in OpenGL, see "the red book":

OpenGL Programming Guide, Mason Woo, Jackie Neider
and Tom Davis, Addison-Wesley.
