Concept of computer generated images and their application by
REBUSTeam
Computer generated images (known as CGI) have become very popular over the past
two decades, and their importance and use will increase even further in the
future because of their wide applicability in various fields. In the area of
movies and films in general CGI has become an essential tool for filmmakers to
bring their visions to the screen, be it by creating computer generated
characters, props, sets, or just simplifying the process of image and sound
editing. Film production ("Filmproduktion
") has been made faster and more efficient in the post production phase,
offering an unprecedented level of freedom and quality.
The success of 3D computer animation and CGI in general started in the early
90s, when software bundles and processing power got more affordable even for
smaller companies, and since then it turned into an accepted art form by
itself. Over the years the technology evolved further and further, lowering the
barrier between art and technology, and even allowing these two extremes to
blend seamlessly.
Creation of 3D graphics:
The creation of CGI and computer animation requires the use of specialized
software products. Several bundles have established on the market, and it is
mainly a question of personal preference which one to pick. After all the
biggest factor in creating convincing digital worlds is the artist himself,
whereas the software is merely the tool to transfer his creativity onto the
screen.
As graphics software became more user-friendly and intuitive, the process of
creating CGI started to resemble its real-world counterparts, like painting,
sculpting, photography and filmmaking. The area of computer animation for
example requires the same steps of "real world" filmmaking, with the addition
of modeling sets, props and characters first. Bringing a mass of "digital clay"
into shape to form a convincing character (or any other object or location to
be shown, for that matter) is the initial step. Then cameras, lights and other
entities are arranged in the virtual space, and animated if necessary. Computer
animation might be called the digital successor to the classic Harryhausen-type
stop-motion animation, although many other ways of animating virtual objects
and characters (like physical simulation or motion-capturing techniques) have
evolved over the years. The last step is called "rendering" and describes the
process of collecting all information of the scene and light setup to process
and output the final image through the lens of a virtual camera, either in the
form of still frames, or a series of frames which create the illusion of
movement.
Television, film production and commercials:
Computer animation and three-dimensional visualization ("Visualisierung
") is widely used in television, commercials and film production. The "small
screen" has proven to be the perfect field for experimenting with newly
developed technology and concepts, and many artists working in the area of
television and commercials have made their way to the movie business. With
software bundles getting cheaper and more accessible, independent artists and
filmmakers seized the opportunity to create their own films and short films, a
development which gave the visual quality of films an enormous boost in the mid
90s. In the area of film production computer animation slowly started replacing
hand-made models and puppets, and even the genre of animated films has gotten a
digital counterpart.
The area of commercials has grown into other branches like industrial
documentations ("Industriefilm")
and corporate video ("Imagefilm"),
and besides entertainment computer animation is also used in the fields of
education, interactive media ("3D
Online
") and military application.
Scientific visualization:
Computer animation produced to present meteorological data, medical imaging,
industriefilm, architecture and technology.
Product design and engineering:
Designers and engineers use special CAD (computer aided design) software for
designing, developing and manufacturing consumer and industrial products.
Product visualization extensively uses modern graphics technology and with the
help of computers, designs can be rotated, cut and manipulated even before
getting manufactured. This greatly helps engineers visualize the product that
they are designing.
