Being Digital

When an item is digitized, it is turned into a giant number. This is equally true of a word, a book, a poem, a song, a movie, a picture. As such it is now subject to all the rules of mathematics, the resulting output becoming any of the above artistic forms. Hence a picture, say, can become a song, say. This leads to an entirely new way of treating art, creation and compositon.

This picture was created from a model in my classroom by Evinn Quinn ('05) using Mathematica.

What's here

This page is dedicated to the applications of mathematics in digital graphics.

The sections below describe digital content or programs. By law names or pictures of current students cannot be publicaly shown.

Artmatic This program is the state of the art in algorithmic picture creating, really a very fancy graphing program. If you like math, you will like this; if you liked the '60's you will like this.

Here is my introduction, explaining how Artmatic produces graphs.


Go to the Seminar class site to see students use a graphing program to mimic Artmatic, and this better understand how it works.

MetaSynth This amazing program is designed to take you to a new level of sound creation. Increasingly music is being produced from sounds as well as notes. Methsynth lets you focus on sound creation while letting you put those sounds in a traditional musical context if you wish. Here are movies created in Artmatic with scores created in Metasynth for the Being Digital course here at Paideia. Check out the lower bandwidth versions (formated for iPod) and then look at the full quality versions of the ones you like.

2005 class
Movie #1: Ferrari Movie by current students. large version
This movie is first because it is a pure example of a digital process. The assignment was to make a movie from a single picture and a single sound, digitally manipulated as much as one wishes. Now what will 14 year old boys want to make a move of? A car, of course. This movie was made from a single picture of a Ferrari and, except for the startup sounds, a single sound of a Ferrari horn. A conceptual tour de force.

Movie#2: This was a collaboration of 4 students. Video's in Artmatic. Score uses cello, symthesizer, voices recorded and manipulated in Amadeus, and Metasynth. It is a great example of mixing sound sources.

Movie#3
: Here a collaboration of 2 students, one creating visuals in Artmatic and one creating the socre on a synthesizer using Garageband.

Histograming and Filering Here a number of students edit and otherwise change pictures. We do this to pictures of Ken Lao because he is the student who began digital mathematics and computer graphics at Paidiea. Besides he deserves it.

Ken is at Pixar today.

Graphics in Mathematica Everything in a computer program is implemented by mathematics. I got into this field because a student (David Amis ()) told me that his store was selling the old showroom copy of Adobe Illustrator for $100, i.e., very cheap. I looked at it and said "matrices" and was hooked, as much by the mathematics of it all as the art of it all.

Programs such as Mathematica allow us to directly manipulate mathematical content. Since pictures and sounds can be digitized (represented as numbers), Mathematica becomes an art program.

Here is my initial Mathematica graphics pixel tutorial.
My Mathematica introduction to vector graphics with pictures by Jeffrey Holtzberg ('03).

3D: Maya The Maya class was created because Alias, the creator of Maya, released a free personal learning edition. Michael Prude ('05) was the first but John Searles ('05) followed quickly. Evinn Quinn taught the first class in it. Here is some of his work.

Maya is an industrial strength program wich allows the creation of simulated 3D objects and animations.

Here is a guitar done by a crurrent student in MAYA.

Here are two simple animations by current students:

Gyro
Screwdriver
Hammer

Analysis of Sounds The combination of mathematical elements into sound

Synthesis of sounds Once you know how a sound is mathmatically made up (see Analysis below) one can synthesize the sound. In my classes I show how to synthesize a gond sound. A gong refers to any of the spectum of sounds created by a spoon hitting a pan to the big gond in Java that rings for three days. I choose this sound because it does not seem "mathematical," and people are surprised when this sound can be created with a mathematical function.

Here is the mathematica code and explanation of the elements of a gong sound.
