In article <843@theseas> nfotis@theseas (Nikolaos Fotis) asked
about the algorithms that Yoichiro Kawaguchi uses in his GROWTH animations.

Last I heard (several years ago), he renders using the LINKS parallel processor
developed at the University of Osaka, running software developed there and/or
at Toyo Links Corporation for "blobby modeling".  See the paper

    %A James F. Blinn
    %T A Generalization of Algebraic Surface Drawing
    %J ACM Trans. on Graphics
    %V 1
    %N 3
    %D July 1982
    %P 235-256

for a description of blobby modeling and rendering.  Other aspects of the
model are created using a recursive tree generator, which I believe
he described in a SIGGRAPH '82 paper.  Except for the rendering, most of it
is pretty simple software, it appears.  What requires more work is the
aesthetic selection of colors, lighting, and motion.
