COMPUTER ART
1. Introduction
What exactly is "digital art" and how shall we judge it? A digital work is, by definition, composed on or translated by or through a binary computer. A digital work is, collectively, a carefully defined set of "0's" and "1's" which have been used to encode data into files that can contain, for example, text, audio or visual information. A 35mm slide once scanned through a "slide scanner" can be "digitized" according to the inclinations of the equipment operator and then immediately printed on a "photo-realistic" inkjet printer at a level of quality to rival that of most any camera store. But is the product of this process a photograph?
With the possibilities offered by computers, peripherals and software, those who become competent with these new and ever-evolving technologies can make or alter images in ways never before available. Many artists and art critics agree, once visual information is converted into binary code it is possible to produce original images that are as visually and aesthetically stunning as those produced through any other medium. But, something more significant happens in that digital transformation; the information on the analogue material is transformed into a digital bitstream and enters the domain of a virtual world where origin has little value. This changes the concept of original artwork and establishes a new paradigm where the act of creation can be participatory and a shared community experience, allowing infinite variations. An analogous example in the world of traditional art might be the sand paintings of the Tibetan monks, of the Navajo of the Americas, and of the Australian aborigines; their works are transitory, community based, ever changing. Though digital imaging can be seen as simply another way to communicate visually and artistically, it is far more complex than traditional media providing a richer and broader artistic experience. Indeed, this ''new digital media'' is engaging us in ways that were not possible with the traditional media of art .
1.1 What is "new media" anyway
New media is, for the most part, a generalized term to describe the many forms of electronic communication which have appeared (or will appear) since the original introduction of online communication which were mainly text-and-static-picture products. By default a definition of new media most often includes any and all modes of moving digital and electronic information from one source to another, such as: special audiovisual effects of any kind; streaming video and streaming audio; 3-D and virtual reality environments and effects; highly interactive user interfaces; mobile presentation and computing capabilities; any kind of communication requiring high-bandwidth, CD and DVD media, telephone and digital data integration, online communities, microdevices with embedded systems programming, live Internet broadcasting (aka: streaming), person-to-person visual communication, one-to-many visual communication.
It can be said that new media emphasizes service over product where one can or may combine various elements of computing technology, telecommunications and intellectual content in a way that permits interactive use by a consumer, receiver or user. So, everyone has the potential to be a contributor/artist. In the emerging digital culture sharing information gives it value. In "new" media, interactivity is presented as a critical element. The idea of consumption is replaced with participation, where the user has a large choice and the freedom to combine various elements into new constructions. In some cases, digital processes can modify themselves and others bringing about a new type of participation and consciousness.
In terms of defining interactivity, web sites are sometimes good examples of new media because such constructs are accessible only through telecommunications technology and also because of the ways in which web design invariably incorporates a variety of media, including text, audio and animation. It is clear to even casual users of the web that the power of the medium comes partly from this ability to affect so many senses.
Even more powerful is the possibility offered by new media to allow an experience to be shaped by the user. In this way new media, unlike traditional forms of media (a book), does not typically exist with a single point of entry to the work or exit from the work. Users are often presented with numerous possibilities for entry, and these choices can then influence the options made available when exiting the work. In this way each encounter with the work can be crafted to be different from any earlier sessions, and a user's interactivity defines the experience [1].
Additionally, users of the term new media quite often emphasize the visual design aspects of the newest of the digital technology experiences. In this way the traditional field of design (both 2D and 3D) has been moved into the twenty-first century and mutated. For example, those who design new media or multimedia works have discourse using newly described operational terms for the design of these new media works, such as: sequenced media, time-based media, aural design, information engineering, interface design, interactive design, 3D computer modeling and animation, and motion graphics.
1.2
How to study digital media
How would one study to do such things? A typical curriculum in "digital media" at a school of art and design might include the following:
2D - Image creation and manipulation, typography, text as image and layered composition work to create art for use in animation, digital video, feature films, interface design and Internet design.
3D - Once the exclusive preserve of high-end workstations, high-resolution 3D image synthesis can now be applied to the desktop in character design and animation, props, vehicles, virtual sets, and more as it extends into the creation of virtual sets and props for movies, television, gaming, Internet and interactive.
Motion Graphics - The way something moves is a vivid expression of its personality. Motion may be created within the computer or sampled from the real world and reapplied in many contexts.
Interactive Design - Train students to engage an audience through creative and intelligent interactive design. An artist must expand his or her abilities to include storytelling skills.
Web - The Internet, in the form of the World Wide Web, is becoming the universal interface. It serves as post office, mall, meeting place, game environment, multimedia distribution medium, and publishing venue. The rapid growth of bandwidth has allowed the integration of sound, image, animations, and video into complex, scripted interactive 'space' on the average Web site.
Combine this advanced and very contemporary curriculum with a heightened awareness of what might be done with digital technologies. Not since the printing press has there evolved such a significant agent for change.
1.3 Gallery art versus new digital media
But what about the difference between gallery art work commonly experienced and the new digital media works and experiments?
Many theorists write on the subject of new media. One of the more effective of these is Lev Manovich [2]. Consider the difference between, as Manovich has suggested in "The Language of New Media" (MIT Press 2001), the " ... dichotomy: an art object in a gallery setting versus a software program in a computer. On entering an exhibition of media art we encounter signs that tell us that we are in the realm of Art: the overall exhibition space is dark, each installation is positioned in a separate, carefully lit space, each accompanied by a label with an artist's name. We know well what to do in this situation: we are supposed to perceive, contemplate, and reflect. Yet these initial signs are misleading. An exhibition of media art points us to very different cultural settings such as a computer games hall or an entertainment park (in each of these one often has to wait in line before getting a chance to 'try' a particular exhibit) and also to a different type of cultural object (and, correspondingly, a different set of behaviors) -- a software program in a computer.''
With regard to Manovich's statement, I think that the sacred public space of the museum with it's perceptual, contemplative and reflective ambiance will not go away but be enhanced and extended beyond the walls of the museum.
Manovich goes on to say, ''In approaching a media artwork, we typically discover some elements of standard human-computer interface (a computer monitor, a mouse; arrows, buttons and so on); we have to read instructions which tell us how to do it; we then have to go through the process of learning its own unique navigational metaphors. All in all, the behaviors which are required of us are intellectual problem solving, systematic experimentation and the quick learning of new tasks. Is it possible to combine these with contemplation, perceptual enjoyment and emotional response? In other words, is it possible to experience the work aesthetically while simultaneously learning how to 'use' it?"
What do art critics and professors of new media think of such exhibitions? Of course, no two locations present the same sorts of works or experiences, but here is an example of one such critique from the "Wirednews" website (January 14, 2002) [3] about a single exhibition by artist Tom Kemp. Each of the writers dealing with this exhibition was considering a work that focuses on the technology of the handheld Palm computer. Kendra Mayfield, of Wired, accurately suggests that, "Artists have long toyed with the latest technologies to create pioneering works of art. In that tradition, Tom Kemp has created what he calls the first 'serious' contemporary artwork produced entirely on the handheld Palm computer. Putting aside the merits of Kemp's specific work, his claim begs a larger question: Is artwork 'serious' simply because it has been done using a previously unexplored medium?"
When considering this same exhibition, Peter Lunenfeld, who teaches in the graduate program in Communication and New Media Design at the Art Center College of Design in Pasadena, California, shared these thoughts, "While such pioneering work is often interesting, the question is whether novelty alone is a useful criterion for art or merely a great excuse for talking about technology. Not everyone thinks that novelty is enough."
On this same subject Benjamin Weil, curator of media arts at the San Francisco Museum of Modern Art also shared his views, "What difference does it make if it has been produced with a Palm of not? I think that deeming it the 'first serious work of art' is somewhat preposterous. I am really suspicious of techno-driven and techno-celebrating projects that desperately seek to be called art. Art is about ideas, not about technology. I would therefore suggest we stop being techno-fetishist, and getting all excited at the gizmo-ization of a practice that is obviously more than just gee whiz!"
What does the artist himself have to say? Although it is clear that other artists have previously created Palmtop computer artworks, Tom Kemp insists that his piece "Analysis" is different from these other Palm-based works. "There are a lot of paintings (done on the Palm). 'Some have been immaculately crafted,' Kemp said. "But they are exhibitions of skill, not necessarily exhibitions of art."
Along this thinking, Pixar's John Lasseter commented with regard to Toy Story that though all the computer scientists, artists and technologists working on Toy Story were excited by the technology alone, the technology in itself was not enough to make an engaging piece of art, something that moved the spirit. There must be a creative, imaginative storyline, theme, in both the message and design of the sensory elements conveyed through the digital media.
Most can agree that digital is revolutionary, unprecedented and marvelously powerful, but art is a balanced implementation of materials, processes and concepts, each of these being given varying priority depending on the focus of the artwork. Certainly all artwork is interpretive, and digital imaging (in its myriad forms) is the first truly new and unprecedented interpretive tool since the introduction of photography in the 1820's. Artworks accomplished with this new digital media have no historical precedent, and the comparison to photography is hardly worthwhile considering the magnitude of effect of digital technology. Where this new media will take us is not yet fully understood, but as Nicholas Negroponte (co-founder of the MIT Media Lab) has written in Being Digital [4], certainly the most facile future users of digital technologies will "live digitally."
2. Tools and Genre of the New Digital Media
Let's look at some of the tools and genre of the new digital media.
2D digital art
There are several excellent software programs for 2D imaging, for example the GIMP (acronym for GNU Image Manipulation Program) [5], a freely distributed piece of software suitable for such tasks as photo retouching, image composition and image authoring. It can be used as a simple paint program, an expert quality photo retouching program, an online batch processing system, a mass production image renderer, a image format converter, etc. Gimp runs on UNIX, Linux, OS/2, and there are Win32 and MacOS X ports. Some of the features of this program include:
Full suite of painting tools including Brush, Pencil, Airbrush, Clone,etc.
Tile based memory management so image size is limited only by available disk space.
Sub-pixel sampling for all paint tools for high quality anti-aliasing
Full alpha channel support
Layers and channels
A Procedural Database for calling internal GIMP functions from external programs as in Script-fu
Advanced scripting capabilities
Multiple Undo/Redo (limited only by diskspace)
Virtually unlimited number of images open at one time
Extremely powerful gradient editor and blend tool.
Load and save animations in a convenient frame-as-layer format.
Transformation tools including rotate, scale, shear and flip.
File formats supported include gif, jpg, png, xpm, tiff, tga, mpeg, ps, pdf, pcx, bmp, and many others.
Load, display, convert, save to many file formats.
Selection tools including rectangle, ellipse, free, fuzzy, bezier and intelligent.
Plug-ins which allow for the easy addition of new file formats and new effect filters.
Supports custom brushes and patterns.
Comparable commercial, proprietary based software are Adobe Photoshop and Corel Draw.
Painter 6.0 is a 2D digital painting program (Figure 1) that simulates the properties of water color art with a digital pad and pressure sensitive stylus. In evaluating the physical processes and product in natural and digital water color, a student made this interesting observation in his thesis [6]:
'' In the comparison of NWC (natural water color) and DWC (digital water color), it must be pointed out that, with DWC, it is easier for the user to control and manipulate images with the undo command and create images in adherence with an initial plan, i.e. an infinitely renewable canvas. NWC is difficult to predict and can not be undone, nor completely revised. If the effect we imagine is not successfully achieved in the NWC brushstroke on the paper, ... we should become creative and imagine how to incorporate this mistaken brushstroke esthetically into the design. This kind of revision that occurs in NWC is possible to simulate in DWC if we turn off the 'undo command,' but it may not be in human nature to do so. The point here is that the inability to endlessly undo mistakes in NWC compared to the DWC process is perhaps an impetus to creativity and gives an edge of excitement to every brushstroke. In fact, the possibility of the 'undo command' diminishes the importance of the movements.'' Akhiro Murakami [6]
Fig. 1 - ''Kao'' by Kaoru Ota in Painter 6.0
Such thoughts remind us that though computer technology may seek to imitate or simulate techniques of traditional art, the computer as a tool and media for art is inherently different than the traditional tools and media of art. This intrinsic difference will shape and define the computer art experience and it will not be the same - nor can it be - as the traditional art form. Another way of saying this is -- how you choose to communicate an idea effects what is communicated. The tool itself will effect the outcome. Marchall McLuhan, former director of the Center for Culture and Technology at the University of Toronto (Canada), wrote two very famous books about this in the 1960s called Understanding Media : The Extensions of Man [7] and The Medium is the Massage [8]. He stated that the ''the medium is the message'' (message and massage being a word play). In other words, the tool (or medium) itself makes us, shapes us, more than the content or product that it delivers. For example the technology of the car changes how cities are constructed and how people live together, regardless of what (content) is transported in the car.
If 2D art is transformed by the computer, let's see what happens when we add dimensions.
3D digital art and beyond . . .
When architects ask for computer visualizations of their designs in three dimensions, they have found the computer to be brutally honest. They may discover their designs on paper can not be built, and given no special treatment or effects, the computer visualization reflects only the artistic aesthetics of the design rather than the inclusion of an artist's or architect's idealizations. One needs to understand that a three dimensional model in the computer is not the same as a drawing on paper.
First, one creates a polygonal model using the Cartesian coordinate system (see CAD chapter). Then, using a rendering software such as POV-Ray [9], the computer ''paints'' a photo realistic image from the polygonal model which includes different types of lighting, textures, and atmospheric conditions. The computer can be far more effective in creating a photo realistic image than traditional art. Using polygonal models, the images produced go beyond simple analogue photography. Adding the fourth dimension - time, we create animation, where each frame is ''painted'' by the computer to create stunning visual and physical effects that are beyond the capabilities of human artists or photographic processes. For example, a human is hardly able to comprehend a million colors or consciously use them. Virtual cameras go where real cameras can not possibly be used. Natural and physical principles can be virtually applied to the digital artwork.
The
3D visualization of Sazaedo [10] (Figure 2), a unique Buddhist temple
in the Aizu region of Japan, and its realtime VRML (Virtual Reality
Modeling Language) [11] walkthrough (Figure 3) demonstrate the
artistic properties of such digital techniques for virtual heritage
displays.
Fig. 2 - Sazaedo, rendered 3D CAD model with detail
Applications
like 3D Studio Max, Maya, Poser (for character animation), and many
others have provided the capability for modeling virtual
environments, enabling 3D "walk through" animations of
historical sites, graphic representation of scanned artifacts, and so
forth. Although there are too many examples to begin to list them
all, one of the most impressive of these "walkthroughs" was
made by the "Virtual Olympia" [12] project (Ogleby, 1999)
directed by Cliff Ogleby of the University of Melbourne. The features
of such complex commercial applications as Max and Maya are so vast
that it is beyond the scope of this chapter, but students are
encouraged to investigate them at their Internet websites [13, 14].
Of course, such sophisticated virtual and simulated effects are best
showcased in animated films like Toy Story, A Bug's Life, Final
Fantasy, Monster's Inc. and so on.
Furthermore,
Internet based interactive realtime games such as Quake by ID
Software [15] are amazing in their artistic detail and simulation of
real world properties in imaginary environments running in realtime
over multi-user and global networks. Though it is true that many such
games focus on violent, combat scenarios, Calef and Vilbrandt point
to a new arena for this media --the interactive virtual museum and
gallery -- in their paper entitled ''Making It Realtime: Exploring
the Use of Optimized Realtime Environments for Historical Simulation
and Education.'' [16] In fact the CAVE experience (see 2.3 below) was
conceived with such a purpose in mind, and we shall see in section
2.5 Simulation, how this concept is expanded to interactive augmented
sculpture.
CAVE
CAVE
is a recursive acronym that stands for CAVE Automatic Virtual
Environment. The CAVE [17] was originally conceived in 1991 by Thomas
DeFanti and Dan Sandin (co-directors of the Electronic Visualization
Laboratory at the University of Illinois at Chicago in the US) and
implemented by Carolina Cruz-Neira (a PhD student). The CAVE is a
projection-based VR display whose design intends to avoid current
limitations of VR systems such as poor image resolution, isolation
from the real world, and inability to simultaneously share virtual
experiences with multiple users. It premiered at the SIGGRAPH '92
conference.
In
brief, the CAVE is a projection-based VR system (Figure 4). The
illusion of immersion is created by projecting stereoscopic computer
graphics into a cube composed of display-screens that completely
surround the viewer. It is coupled with a head and hand tracking
system to produce the correct stereo perspective and to isolate the
position and orientation of a three-dimensional input device. A sound
system provides audio feedback. The viewer explores the virtual world
by moving around inside the cube and grabbing objects with a
three-button wand-like device. The CAVE blends real and virtual
objects in the same space so that a person has an unoccluded view of
his/her own body as it interacts with the virtual objects.
Fig.
4 - CG model of CAVE
In
the CAVE, the viewer is completely surrounded by screens. Even though
the viewer's field of view can vary for each individual screen, the
total field of view for the system can be up to 360 degrees
horizontal assuming a closed cube.
In
the CAVE, multiple users can easily share the virtual experience by
having each user wear a pair of stereo glasses. Unlike other virtual
reality systems, the users interact with each other and not with
their electronic ghosts; they can carry on a discussion inside the
CAVE just as they would in a conference room setting. The ability to
offer guided tours through data is a direct consequence of the
ability to share the CAVE with multiple users. Typically an expert
navigator can control the path traversed through the data while other
viewers observe.
The
wrap-around screens in the CAVE have great potential for successive
refinement of images. The CAVE can be used to navigate the virtual
space in realtime. Once a desired location has been reached, the
viewer can request an enhanced non real time rendering to explore
large and complex data or large stores of precomputed data that will
not ordinarily respond well in realtime. The users, although they can
no longer navigate, can still pan around without disorientation.
Sound plays an important role in determining the immersiveness of an
experience. The interaction between visuals and sound is very
important feature of the CAVE experience.
At
the University of Aizu, Japan, So Yamaoka is developing realtime
music driven animation [18]. Music is analyzed in the computer using
two audio analysis methods and two kinds of filters. An animation is
then generated from the software; colored and textured shapes are
moved in 3D space according to the audio analysis programming. Figure
5 shows a frame from the animation, in which the green circle, red
square, and blue triangle move, expand, shrink - dance to the music
in realtime.
An
excellent example of the use of the CAVE concept for a definitive
historical and artistic experience is Benjamin Britton's (University
of Cincinnati) VR Cave at Lascaux installation, initiated in 1995.
While the real prehistoric cave of Lascaux exists in the south of
France, it is now closed to the public and sealed to preserve the
thousands of prehistoric paintings on the cave's walls from moisture
and bacteria.
Fig. 6 - One frame of the VR Lascaux by Benjamin Britton
The VR Lascaux (Figure 6) uses PC technology, motion sensors, and headphones, that are strapped onto the head for the "immersive" experience in the computer program. The motion sensors send movement commands to the computer controlled installation. The virtual reality computer then translates the motion of the head, looking up or down, turning left and right, into real time computer animation movement that mimics the direction that the headmounted sensors have turned. The VR Lascaux is very high quality, 16 million color, full motion renderings. Thousands of detailed prehistoric paintings are represented in the VR cave, allowing viewers some experience of this now forbidden treasure.
The immersive environment of the VR Lascaux gives us back somewhat of the real Lascaux, but just as importantly it is an artwork in itself joining past, present and future. Perhaps, the words of the artist can best tell us about this digital work:
"Humanity is terrified of the future, holds civilization in contempt, and is alienated from the natural world. We must realize the relationship of our society today with human society of the most ancient past and most distant future. To be a human being is to be trapped in the river of time with countless other living forms with whom one can communicate; and, finding that the beauty of this inescapable fact is essential for making life on this plane worthwhile. To connect our culture to the cultures of all time is the purpose of LASCAUX: to take part in the virtually endless tradition of life." Benjamin Britton [19]
Mathematics
in digital art
''Sometimes
the pictures one gets remind one of some familiar system in nature.
And sometimes they look like the creations of a human artist. But
often they are something different. They have parts reminiscent of
nature. And parts that one could imagine being created by human
artists. But then they have unexpected elements, like nothing seen
before, together with a vast range of details far beyond what any
unaided artist could ever produce.'' Stephen Wolfram

Stephen
Wolfram [20], scientist, creator of Mathematica [21], and
author of A New Kind of Science (cellular automata theory) is
speaking about Graphica
[22], a collection of unique color illustrations, created with
Mathematica software, a technical visualization and modeling
tool, using algebra, trigonometry, calculus, and other fields of
traditional mathematics. The images in Figures 7, 8 and 9 illustrate
the creative power of mathematics in art.

Other
visually stunning contributions from the world of mathematics include
fractals, which (simply stated) are irregular fragmented shapes that
exhibit intricate structure at all sizes so that details are
reminiscent of the entire object ( a property known as
self-similarity). Julia [23] and Mandelbrot [24] sets are the source
of some of the most beautiful fractal creations (Figures 10 &11).

Simulation
''. . . the use of computer hardware and software to aid the artist in the creative process can be seen as a set of sophisticated tools, analogous to the use of
the brush and canvas or the chisel and marble, leading to machine mediated augmentation of human creativity.'' [27]
Computer technology can aid the artistic sculpture process from sketching or designing the initial idea and exploring a variety of different shapes to the physical production of the sculpture. Computer artists/scientists/specialists such as Carlo Sequin [28], Bruce Beasley [29], Stewart Dickson [30] and Helaman Ferguson [31] are doing this in unique ways. The reader is encouraged to investigate the aforementioned artists' related websites (from the references at the end of this chapter) in order to see and understand this new computer assisted art.
A
few artists/computer scientists are conducting a more searching
exploration of forms that can be generated only with computers. Two
of these are William Latham and Stephen Todd, collaborating on
creating stunningly complex, virtual shapes using methods of natural
evolution and artificial life. Their computer programming sets up a
basis of aesthetic choices so that the final form is not
predetermined, and the evolutionary program gives rise to a new type
of kinetic ''virtual'' sculpture. [32] This art goes beyond using a
new tool to perform old artistic tricks.
Alexei Sourin is a computer scientist interested in various craft forms such as carving, embossing (the art of decorating metal by means of hammers and punches to create a raised surface), and woodcutting. He has implemented an interactive digital system for virtual embossing and woodcuts with realistic rendering [33]. A pressure sensitive graphics tablet and a six degree of freedom haptic input device is used to realistically simulate the depth of penetration of the tools used in these traditional crafts. What is interesting about Sourin's system is that it uses interactive function-based shape modeling [34] where relatively small formulae are used rather than thousands of polygons. Interactive modification of the function model with concurrent visualization of the respective parts allows interactivity and any required level of detail leading to photo-realistic appearance of the resulting shapes. What is remarkable about Sourin's work is his complete digital synthesis of a traditional three dimensional art form.
Using technology based on function representation (F-rep) of geometric models [34], computer scientists, Valery Adzhiev and Alexander Pasko, Russian sculptor, Igor Seleznev, and an international team of researchers are collaborating on an approach which they call ''augmented sculpting.'' [27] A computer model is made of an existing physical sculpture and then manipulated to produce new shapes that can be manufactured with traditional techniques or computerized rapid prototyping and 3D printers [35] to produce a new, different physical sculpture.
Function representation methods actually employ constructivist techniques that allow the emulation of physical or virtual ''building blocks'' in the form of geometric primitive shapes that can be combined in complex spatial relationships. The team has developed a specialized high-level language, HyperfFun [36], which allows for a parameterised description of functionally-based multidimensional geometric shapes, and recently, ''Hypervolume'' modeling [37] has been introduced allowing for more complex effects. For example, one could design the material block from which a sculpture is carved using the geometric model of a different sculpture or some other object with different material properties and yet retain features and elements of each depending on their intersections and unions. Furthermore, the HyperFun toolkit supports an original technique to successfully metamorphose key-shapes of differing topologies and also obtain their intermediate shapes. Such multidimensionality, metamorphosis of shape and material, begins to enter the world of analysis and simulation that is beyond our imagination.
Perhaps, the ''Augmented Sculpture Installation'' [27] is the next step beyond the CAVE, where one not only experiences but actually creates objects of art, in which an ''interactive sculpture'' is both physical and virtual and where the virtual world is overlaid on the physical world, where the tool is inseparable from the creation . . . is as real as computer art gets.
(Jun, what I mean by ''real as it gets'' is genuine, authentic experience.)
3. Conclusion
The computer is a ubiquitous device that because of its power can be used to simulate, replace and extend beyond the reaches of its analogue counterparts. But what, in the end,
is computer art? If we follow Marshall McLuhan's the ''media is the message,'' then we might consider programming the essence of computer art where no visualization is taking place at all. Some say that technology alone is not enough to create art; art is about ideas. But, ''living digitally'' will birth new ideas about culture, nature, life, death, the universe and everything -- and that will create new art, digitally ... certainly.
''The personal and social consequences of any medium - that is, of any
extension of ourselves - result from the new scale that is introduced into
our affairs by each extension of ourselves, or by any new technology.''
Marshall
McLuhan [7]

Answers to Exercises:
Note: The nature of computer art and its interpretation is for the most part subjective. Therefore, answers to the exercise questions are not precise and many possibilities exist beyond the sample answers given here. However, the student should include some of the points from the chapter reading, and it is hoped be inspired to some creative answers as well.
1. Describe several ways that ''new media'' and traditional art are the same? are different?
-- are the same?
New media can be as artistically valid as traditional art.
New media can be participatory, a community experience but on a broader scale than traditional art.
--are different?
New media is created and exists digitally and electronically having little weight or size. Because its physical existence is so small, it is sometimes referred to as virtual and can move quickly across and through a vast virtual domain; origin has little value compared to traditional art, which is made of physical materials such as paint, clay, stone, metal, wood, etc. and exists in a discrete locale. Therefore, origin and ownership of “new media” are difficult to prove, changing the concept of original artwork.
New media lends itself easily to inexpensive and exact reproductions of “ new media” works unlike traditional artworks.
New media is service rather than product oriented and promotes interactivity.
New media can have multiple points of entry into and exit from the work on demand by the user.
New media has new terminology to describe its new capabilities, such as: sequenced media, time-based media, aural design, information engineering, interface design, interactive design, 3D computer modeling and animation, and motion graphics.
2. How might you study to be a computer artist?
Study web design.
Use a digital camera and software to modify images.
Study any 3D design software.
Study 2D painting software.
Study formal design; the rules of design in traditional art are still meaningful
in new media.
Study the theory of light and color.
Study music and sound.
What kinds of computer tools would you use? (Describe them briefly.)
PC workstation with higher end graphics and audio capability, digital camera, pressure sensitive tablet, digital music keyboard, 3D scanners, digital motion capture devices, 2D/3D printers.
Software such as Open GL, POV-Ray, Maya, 3D Studio MAX, Adobe Photoshop, GIMP, Corel Draw, Painter, Flash, Shockwave, film editing, music authoring, etc.
3. Do an Internet search for computer art and artists mentioned in this chapter and others not mentioned. Describe their work and give specific URLs.

4. Create a piece of computer art or ''new media''.
5. Read about the CAVE and the Augmented Sculpture Installation [27 - V. Adzhiev, et al., “Augmented Sculpture: Computer Ghosts of Physical Artifacts,” Leonardo, Vol. 36, No.3,
pp. 221-219, 2003, URL: http://cis.k.hosei.ac.jp/~F-rep/ASP_Leonardo.pdf ]; then, design
your own CAVE experience.
6. What do you think Mandelbrot is saying in:
''Clouds are not spheres, mountains are not cones, coastlines are not circles, and bark is not smooth, nor does lightning travel in a straight line.''
What meaning does this have for the computer artist and artist in general?
Mandelbrot was speaking about how the Euclidean geometry of cones and spheres does not describe reflect the world of nature. He was referring to the complexity and fractal nature of the natural world and how it can be represented by repetitive mathematical patterns such as Mandelbrot's fractal math. For the computer artist, it is the merging of art, mathematics, and science through the use of a computer. For all artists in general, the complexity of Mandelbrot's non-Euclidean world presents new, fascinating and complex views of the natural world that challenge old perceptions and inspire new interpretations.
7. Do a comparison of 3D digital art, mathematic generated art, and function-based (function representation generated) art. ((Include the key features of each.)
3D
digital art is created by software like 3D Studio MAX or Alias
Wavefront's Maya. They are animation packages based on the use of
polygonal models. Animation movie companies such as Pixar and Disney
use this type of software to create expensive feature animations. It
might be called commercial digital art.
Mathematically
generated digital art like fractals are used by artists and
scientists. This mathematically generated art may look like nature,
may even describe aspects of nature, but is not natural in the sense
of the traditional meaning. The level of detail is so great that an
artist could not make these by hand. It could be called automatic
art.
Function representation based digital art is
based on the use of functions to define geometric shapes, their
volume and real metamorphosis over time. It is being developed by
computer scientists and offers new exciting levels of computer
modeling for the future. For example, it can allow for computerized
3D printing of complex, compound shapes not able to be imagined or
constructed manually. It could be a multidimensional digital art of
the future.
8. Explain ''the media is the message''. Give examples.
Media can be considered as tools, and as man creates tools, those tools by their very nature effect man regardless of the content or lack of content they may deliver. For example, it is often said that “guns don't kill people, people kill people” as a rationale against gun control. However, consider the recent phenomenon of “driveby” shootings in the U.S. -- by contrast,
a “driveby” knifing is just not very effective. So, this gruesome example demonstrates how a tool facilitates human action. Another example, an unforeseen side affect of the invention of the printing press was the fragmentation of society and individual isolation, as the portable book could be read in private diminishing the oral tradition and collective community.
