Andrew
Glassner's Notebook is a regular column in
IEEE Computer Graphics & Applications. The articles
from January 1996 through March 1999 have been collected,
edited and expanded in the book Andrew
Glassner's Notebook,
published by Morgan-Kaufmann. The articles from May 1999
to
November 2001 have been edited and expanded in the
book Andrew
Glassner's Other Notebook, published by AK Peters.
My columns from January 2002 to November 2004 have been
updated, revised, and expanded, and will be published in
Morphs,
Mallards, and Montages: Computer-Aided Imagination
(published by AK Peters,
to appear Summer 2004).
These pages collect notes, errata, and comments from the original
columns, and those that have not yet been printed in book form.

About Face describes a system that I built to help
me sort through the thousands of typefaces that I have on
my computer. You can choose values for a half-dozen different
criteria such as density, border length, aspect ratio, and
the degree of match between the capital E and F character.

Around and Around
looked into the possibility of replacing the circles that are
part of every Spirograph toy with more interesting curves. Specifically,
I build wheels and frames out of Bezier curves, and then roll
the wheel around the frame. This generalizes a class of mathematical
curves known as roulettes.

Digital Cubism, Part I introduced a technique I call
the multicamera collage. In this system, ray-tracing
is used to help you create images and animations by building
collages out of images that you create with any 3D package.

Digital Cubism, Part II describes the mathematics
behind the multicamera collage, and describes how to use the
system for both stills and animated sequences (this work is
patent pending).

Crop Circles, Part I talks about the fascinating cultural,
geometric, and historic qualities of crop formations. I describe
the basic geometry behind most crop patterns, and provide
clear descriptions and proofs of the oft-mentioned "Hawkins'
Theorems," including the elusive Fifth Theorem.

Crop Circles, Part II continues the discussion from
Part I, and introduces my Crop language for creating
crop circle designs. I also talk about how we made the parking-lot
"crop circle" formation at the left. You can learn
more about the Crop language here.
