This function is in the Utility Library because it uses a combination of rotation and translation routines to produce the matrix for transforming from world to viewing coordinates.
Intensity attenuation is performed in the empirical OpenGL lighting model as an inverse quadratic function, where distance d is measured from the light position to a point on an object surface.
In OpenGL, the current surface is referred to as the "source" and the current pixel color stored in the frame buffer is referred to as the "destination".

 Introduction
OpenGL provides a set of commands that allow the specification of geometric objects in two or three dimensions, using the provided primatives, together with commands that control how these objects are rendered (drawn).
Since OpenGL drawing commands are limited to those that generate simple geometric primitives (points, lines, and polygons), the OpenGL Utility Toolkit (GLUT) has been created to aid in the development of more complicated three-dimensional objects such as a sphere, a torus, and even a teapot.
OpenGL Utility Toolkit (GLUT) is a window-system-independent toolkit, written by Mark Kilgard, to hide the complexities of differing window APIs.

The OpenGL Utility Toolkit (GLUT) is a programming interface with ANSI C and FORTRAN bindings for writing window system independent OpenGL programs.
Necessary interactions between OpenGL and the window system such as creating and binding an OpenGL context to a window are described separately from the OpenGL specification in a window system dependent specification.
Note: This is inconsistent with OpenGL's coordinate scheme that generally considers the lower left hand coordinate of a window to be at (0,0) but is consistent with most popular window systems.
