Tessellations: Technology and Culture
Design is part of the human consciousness. Culture is how
people see and do things from a historical prospective.
The images shown here with the Java graphics are rooted
in thousands of years of use and living.
Escher began his regular plane division work in 1936 in
Spain. He got famous in the 50's. He was unique in his
vision and passion and he used to say "I'm walking
around all by myself here." His prints were all over USA
in the 60's when I was in college in Wisconsin and Michigan.
Five years after he died, in 1977 I did the computer programs
while I was teaching at the University of Illinois. That
was before the era of personal computers and desktop publishing.
I published my technical papers in 1979 and 1980. I have
collected images of regular plane division for quite a while.
It was not until I got on the Internet in 1997 that I see
other people doing Escher inspired art. The Internet made
a lot of resources available. So we don't feel the isolation
and loneliness that Escher expressed.
You can put an interlocking shape on the web by scanning or
computer paint programs(Adobe, Corel, etc.). That creates a
pixel based image. Some people asked me "Why use JAVA?" JAVA
programs are based on a mathematical description of the shape.
The colors are more uniform and the shapes have a simple clean
look. Because the size, color and angles are defined by a
set of parameters, the image can be changed dynamically while
the shape is shown on the webpage. I learn a lot more about
the geometry rules when I do the JAVA programs.
This is for your delight!
Enjoy the visual overload !

Hints and shortcuts to make tessellations
Why do JAVA or JavaScript?
I started using JAVA to do these tessellations in April 98.
JAVA is like C, which is a versatile programming language.
Doing graphics on the monitor with C is simple. JAVA graphics
output is limited to this sandbox on the webpage (of the browser).
The size and location of the sandbox is defined by HTML,
which invokes the JAVA applet. I learn to
use JavaScript to allow the viewer to interact with the Java
Virtual Machine. JavaScript is like REXX. It is good with
command parsing. JavaScript is perfect for interfacing JAVA
with the HTML script. What you see are the buttons that allow
you to change the image within the sandbox of JAVA graphics.
I feel the time invested in the JAVA language is well spent
because the language is so useful and there is a real commitment
from Sun Microsystem to make this a universal language.
Like other people I know, I learn this in my spare time
without formal training. This is because the language is well
designed and there are so many good books on the subject. It
helped me a lot to have people around like Steven, Gary Steiner,
Brian Fan and Galen Miller to bounce off ideas and questions.
Please give me
feedback or send me an
email if you have an idea or something to say.
CD is available that contains 500 images, 40 graphic Java programs with source code, fast viewing for all designs without an Internet connections. This CD can save you many hours of downloading. Avoid any missing pictures. Less waiting on the Internet and less computer troubles. Please inquire with email.
