Animac: a multiprocessor architecture for real-time computer animation (graphics, shadows, vlsi)

Abstract: Advances in integrated circuit technology have been largely responsible for the growth of the computer graphics industry. This technology promises additional growth through the remainder of the century. This dissertation addresses how this future technology can be harnessed and used to construct very high performance real-time computer graphics systems. This thesis proposes a new architecture for real-time animation engines. The ANIMAC architecture achieves high performance by utilizing a two-dimensional array of processors that determine visible surfaces in parallel. An array of sixteen processors with only nearest neighbor interprocessor communications can produce real-time shadowed images of scenes containing 100, 000 triangles. The ANIMAC architecture is based upon analysis and simulations of various parallelization techniques. These simulations suggest that the viewing space be spatially subdivided and that each processor produce a visible surface image for several viewing space subvolumes. Simple assignments of viewing space subvolumes to processors are shown to offer high parallel efficiencies. Simulations of parallel algorithms were driven with data derived from real scenes since analysis of scene composition suggested that using simplistic models of scene composition might lead to incorrect results. The ANIMAC architecture required the development of a shadowing algorithm which was tailored to its parallel environment. This algorithm separates shadowing into local and foreign effects. Its implementation allows individual processors to compute shadowing effects for their image regions utilizing only very local information. The design of the ANIMAC processors makes extensive use of new VLSI architectures. A formerly proposed processor per object architecture is used to determine visible surfaces while new processor per object and processor per pixel architectures are used to determine shadowing effects. It is estimated that the ANIMAC architecture can be realized in the early 1990's. Realizing this architecture will require considerable amounts of hardware and capital yet its cost will not be out of line when compared with today's real-time computer graphics systems.

An Indexed Bibliography on Computer Animation

Abstract: Although the computer plays an ever increasing role in animation, the term ?computer animation? is imprecise and sometimes can be misleading, since the computer can play a variety of different roles. A popular and simple way of classifying animation systems is to distinguish between computer-assisted and modeled animation.

VLSI-Architectures for Computer Graphics.

Abstract: Both academic researchers and commercial concerns are increasingly interested in applying VLSI technologies to graphics systems: For researchers, graphics systems offer an attractive model for study of computer architectures in VLSI: these systems have a small well-defined set of operations and simple data and control structures, making these systems ripe for applying parallelism and modularization techniques; many of these systems, especially the interactive high-resolution color ones, have severe computation demands that are unfulfilled by solutions embodied in current systems. For commercial concerns, there is a rapidly increasing market for interactive graphics systems as personal workstations in which graphics displays replace text-only terminals. In this paper, we cover: a) the conceptual organization of a “generic” graphics system and its realization in several state-of-the-art commercial products; b) the architecture of several recent VLSI chips and systems and their likely effect on the organization of future graphics systems; c) the architecture of several VLSI-based systems that are currently subjects of research. The design strategies used in these systems — the structure of parallelism, intertwining of data and computation, the tradeoff between custom and off-the-shelf parts — may provide insights into other applications as well.

Computer graphics : visual technology and art

Abstract: Imagine that you get such certain awesome experience and knowledge by only reading a book. How can? It seems to be greater when a book can be the best thing to discover. Books now will appear in printed and soft file collection. One of them is this book computer graphics visual technology and art. It is so usual with the printed books. However, many people sometimes have no space to bring the book for them; this is why they can't read the book wherever they want.

One particular interactive graphics program which displays z-plane diagrams and the related frequency response graphs is described and examples of the display presented. Some experience in using this software is presented.

Interactive graphics for geometry generation - A program with a contemporary design

Abstract: The aerodynamic design process is now strongly influenced by the application of advanced computational tools due mainly to recent advances in computer capabilities. Today's aerodynamic analysis codes require large amounts of geometric data to define the surfaces in sufficient detail for proper analysis. A program has been developed to aid the engineer in generating geometric models for computational aerodynamics codes. The program, Interactive Graphics for Geometry Generation (I3G), is not dramatically different on the "outside" from other interactive graphics programs of this type. It is, however, different on the "inside," i.e., in how it performs its functions. I3G is capable of accepting input from a variety of geometry sources and can support the generation of geometric models for many different computational codes. User-friendly operation encourages program use. Graphics devices ranging from sophisticated systems to low-cost display-only terminals can be easily supported by I3G. The program's modular structure allows new modeling capabilities to be readily incorporated. A system for indexing and retrieving existing geometric models is available to the user. In summary, "flexibility" is the key word behind I3G's basic design and structure. This feature allows modifications and enhancements to be readily made as needs change or arise. Succinctly, it is a program designed to last.

Communications and Graphics

Abstract: Until recently, computer graphics has been used as an”end” and not so much as a”means”. As an”end”, graphic output ranges from simple bar charts to three dimensional surface charts to CAD/CAM layouts. Applications have long existed to convert data into graphics. There have been many sophisticated libraries and stand alone products which draw these charts on any number of devices and in a multitude of resolutions. There never has been any serious consideration of graphics as a general communication tool until the recent introductions of both hardware and software technology that made the throughput acceptable and visibly clear.

Critical Issues in Computer Graphics Education for Graphics Design

Abstract: With the recent introduction of sophisticated computer graphics design systems into the marketplace, design educators must now come to terms with radical changes in design methodology and stylistic content. The advantages and limitations of these new technologies will force significant departures from current curricula and will demand the development of novel program designs, and new teaching strategies.
