	Source for code given in the Appendices
	(c)Roy Hall - 1988,1989
------------------------------------------------------------------------------

	This code was developed to test and demonstrate concepts
	discussed in "Illumination and Color for Computer Generated
	Imagery" (1989 from Springer-Verlag).  While the code was
	used in the generation of the diagrams and images presented
	in the text, it may still contain bugs.  The user is cautioned
	to independently verify that the code is suitable to his/her
	needs.  This code is distributed on an "as is" basis with
	all faults and without any implied or expressed warranties
	or support from either the author, Roy Hall, or from
	Springer-Verlag Publishers.

	I am making this code available to the user community.  You
	are free to use it as you wish.  In return I request two
	things.  First, that this README file always stays with any
	copy of the source, more specifically, that proper credit is
	given to the original author.  Second, that any corrections,
	improvements, etc. are passed back to the author for inclusion
	in subsequent distribution and editions of the book.

	Please note that the code was written for clarity of presentation,
	not for performance.  You will find that optimizations can be
	easily made.  Please do not report these as I will not incorporate
	them into future releases.  Note also that this code relects
	current work I am involved in and may differ slightly from
	that presented in the text.

	There have been some additions to the distribution (16 July 90):
		Corrections:    list of corrections for the book and
				the code
		Slectral/:      a directory containing a few spectral
				curves to help get you started
