The scientific computer user presents a unique challenge to the graphics system designer. If the graphics system is properly designed and implemented, computergraphics becomes a vital research tool for the scientific user. These users' desires and expectations play an important role in every phase of the design *** paper describes the philosophy of the graphics system at the National Center for Atmospheric Research (NCAR) and its implementation. Details of algorithms are not presented; rather the purpose has been to describe a successful computergraphics system which may serve as a guide for other designers who desire to provide practical computergraphics. This graphics system operates under a batch-mode computer system without using interactive terminals.

The ability to specify nonplanar 3D curves is of fundamental importance in 3D modeling and animation systems. Effective techniques for specifying such curves using 2D input devices are desirable, but existing methods typically require the user to edit the curve from several viewpoints. We present a novel method for specifying 3D curves with 2D input from a single viewpoint. The user first draws the curve as it appears from the current viewpoint, and then draws its shadow on the floor plane. The system correlates the curve with its shadow to compute the curve's 3D shape. This method is more `natural' than existing methods in that it leverages skills that many artists and designers have developed from work with pencil and paper.

We present two algorithms for pictures of polyhedral scenes. These algorithms have been conjectured (and used for some time), but only now been verified. The combinatorial algorithm, proposed by Sugihara, uses counts on the incidence structure to characterize pictures which are generically the projection of sharp polyhedral scenes of planes and points. The geometric algorithm, described by Clerk Maxwell and rediscovered in the last decade, uses a reciprocal diagram in the plane to characterize pictures of strict oriented polyhedra in space.

Virtual avatars have been employed in many contexts, from simple conversational agents to communicating the internal state and intentions of large robots when interacting with humans. Rarely, however, are they employed in scenarios which require non-verbal communication of spatial information or dynamic interaction from a variety of perspectives. When presented on a flat screen, many illusions and visual artifacts interfere with such applications, which leads to a strong preference for physically-actuated heads and faces. By adjusting the perspective projection used to render 3D avatars to match a viewer's physical perspective, they could provide a useful middle ground between typical 2D/3D avatar representations, which are often ambiguous in their spatial relationships, and physically-actuated heads/faces, which can be difficult to construct or impractical to use in some environments. A user study was conducted to determine to what extent a head-tracked perspective projection scheme was able to mitigate the issues in readability of a 3D avatar's expression or gaze target compared to use of a standard perspective projection. To the authors' knowledge, this is the first user study to perform such a comparison, and the results show not only an overall improvement in viewers' accuracy when attempting to follow the avatar's gaze, but a reduction in spatial biases in predictions made from oblique viewing angles.

As part of a study of methods and strategies for problem solving in a distributed environment [LessgO], we have been investigating techniques suitable for use in debugging programs written for implementation on distributed processing networks. Traditional debugging methods emphasize techniques that apply at the level of computation units and generally allow users to examine, and possibly alter, the state of a computation. interactive debugging monitors are probably the most powerful implementations of the traditional method and usually permit a user to examine an entire snapshot of 'system state at any step of the computation. It is the Job of the debugger (usually a person directing the error search) to determine what units are relevant to some problem, examine the units in whatever fashion is available, and then fit the results of these examinations into a model of how the computation works. Two elements essential to the successful completion of the debugging task are evident here: The ability to monitor, in some meaningful way, the relevant system activity so as to understand how system behavior differs from the debugger's model, and the ability to perform experiments based (implicitly or explicitly) on the information gathered. Through the interaction of these two elements a debugger attempts to gain an understanding of the causes of an error or at least to note where the implementation and the expected behavior differ In attempting to attain this understanding (which is the difficult part of debugging) a debugger abstracts parts of the program's activity to match parts of the debugger's model of how the system is supposed to function. Through experiments that perturb parts of the system in a controlled fashion, the debugger is attempting to verify that the implementation, the abstractions and the model fit together in a meaningful way. Traditional debugging tools support only a unit-at-a-time, state-based methodology and hence cannot provide the higher-level vi
