[comp.graphics] CIE Chromaticity Diagram Algorithm Needed

kellygo@othello.UUCP (10/01/87)

Hello,

I would like to be able to generate the 1931 CIE chromaticity diagram
(shown below), using an IBM PC compatible and writing in C.  Also at
my disposal is a graphics package (IMAGER-AT) that allows me to
manipulate individual pixels. The diagram will be used to evaluate the
color capabilities of an RGB display.

I don't know much about color theory, so it would be a great help to
receive any information on generating the CIE diagram.  Information
could take the form of references to the literature, textbooks,
approaches, programs (any language, except assembler) and especially
algorithms!

                  G               
                 ^
                /g\
               / g \
              / bgr \
             / white \
            /bb    rr \
         B /___________\ R
                                                        o
           ^^^^^^^^ CIE chromaticity diagram (CIE 1931 2  Standard Observer)

Thanks in advance,
