Reason for this has been a project named as UNUI.
UNUI is an improvisation project by voice/sound artist Aava Uusikuu, visual artist Outi Aho and sound editor Jouni Korhonen. "Unui" is a word of an imaginary ancient language. It is some kind of glossolalia, enjoyable movement of a mouth without closed meaning. Live shows contain visual structures, organic soundscapes and affective human cries, murmurs, mumbling, babbling, singing and speaking weird languages. Each performance is different, because the song, sound and visual elements are generated during the presentation. (https://www.facebook.com/#!/pages/Unui/188416394512662?sk=info)My role has been to provide the interactive visual improvisation for the presentation. I have used my drawings, paintings and photographs as the source of visual material. During the show, this material is animated, combined and manipulated both by the computer (based on the improvised sound) and by myself .
I wanted to program the software by myself. I selected Processing, because I already knew some basics of it due to fact that it is used in conjunction with arduino. I did study other possibilites also (such as PureData and VVV) but I decided to use processing because I already have some basic knowledge of C and C++ .Otherwise I didn´t knew anything about graphical capabilities of the Processing or Java.
As an incurable book-a-holic. I decided to buy several Processing books to support my learning path. Actually I bought four of them. I do not regret buying any of those because all of the have special unique merits. Below some of my feelings related to those books.
Getting Started with Processing, Casey Reas & Ben Fry, 2010This small booklet (194 pages) is a good and a very quick starting point to learn and understand Processing. I went through the whole book and all examples just using two days. After that I had a confidence that I can start my part of the UNUI project with Processing. The book is concise and explains the basics very thoroughly and clearly. I could have even managed to do my program only by using this book and the Processing web side if I would have more time. However, I wanted to have some kind of paper manual also for quick reference. So I bought also:
Processing, A programming Handbook for Visual Designers and Artist, , Casey Reas & Ben Fry, 2007This book is what is says to be - a Handbookwith a capital letter. It has 710 pages full of information and examples. This book works well if I need to check some basic things. I also like that the book contains information about actual Art projects and interviews of the Artists. I also like that this book has hard covers which make it easy to use it as a "bed-time reading book". The minuses are that the book has rarely any color pictures.
Processing for Visual Artists, Andrew Glassner, 2010I admit, that I bought this book mainly due to its cover picture that somehow appealed to me. I also liked that the book has plenty of color pictures and a lot of visually interesting projects. What I have liked about this book is that it explains also a lot of principles of computer generated graphics and image processing. Examples are well thought over and the book proceeds in a iterative way from easy to more complicated examples. What I don't personally like is that the text has been written in a very chitchatting way. I have not yet went though all examples, but I have been planning to do it soon. The minuses are that the book has soft covers and glued quite poorly. I am afraid the pages will fall off very soon.
Learning Processing, A Beginner´s Guide to Programming Images, Animation, and Interaction, Daniel Shiffman, 2008I bought this book because I first found the coding examples of the book from the web. They seemed to be very interesting and useful for me. Also I liked that the book also covered some examples about Video and Sound processing. The book is intended to be used as text book for introductory level programming course. Therefore the structure of the book is organized as lessons with related exercises and small projects. The book is maybe too basic for me, but as I already mentioned, examples are great. I also liked that the author did talk something about Java, too.
