Today's software systems for medical visualization still suffer from a shortage of practical applications due to their lack of usability with respect to a large variety of users with different computer-skills and experiences. Furthermore, progress is often hampered by the lack of adequate software tools that allow research ideas to be rapidly accomplished, evaluated, and brought into routine. We developed an integrated software environment that is distinct because it, on the one hand, provides an application-builder toolbox for medical diagnosis and therapy. And, on the other hand, it allows for the development, integration, and user-centered evaluation of existing and new interaction techniques in 2-D, 3-D, and Virtual Reality (VR). The environment's interaction support is based on communicating application objects that employ a sophisticated message-based inter-object communication. In addition, the system contains a component for user-adapted interaction and system support. The system has been used for several clinical applications which are briefly described at the end of this paper. Copyright (C) 1996 Elsevier science Ltd.

There are two broad categories of research animation system: those designed to support a particular motion synthesis tool, and those whose implementation is intended to foster a particular form of motion generator design (such as object orientation). However, neither of these approaches really provides significant assistance to the animation researcher wishing to quickly evaluate arbitrary new motion production algorithms against existing techniques. This paper addresses that need by presenting an animation system specifically designed to provide a helpful framework for a wide variety of motion generators, and discusses how these may be implemented and used.

The CAPSE environment for computer Aided Parallel Software Engineering is intended to assist the developer in the crucial task of parallel programming. The methodology of CAPSE is based on direct manipulative graphical creation and editing of scalable workload characterizations of MIMD algorithms. This paper presents the basic concepts of this methodology and an example of a parallel Poisson solver. The workload characterization representing the computation and communication behavior of the algorithm is based on directed acyclic task graphs, which achieve scalability by composing the task graph of scalable basic patterns instead of single node and arcs. The composition and the usage of these basic patterns is described in the light of designing the Poisson solver algorithm. The resulting task graph is used to predict the program's performance on a nCUBE 2 distributed memory machine and the PAPS simulator.
Current compilation systems for distributed memory computers have to integrate new techniques to support the highly complex task of producing efficient programs for parallel systems. Two techniques, program comprehens...

The discussion on the advantages and disadvantages of 2D, 3D, and VR interfaces and their applicability to different types of systems, users, and information led to a series of stand-alone implementations that lack the possibility of realizing ail integrated approach. The acceptance of the different interaction techniques will depend on their success in practical applications, i.e. with systems that are used by different users for different purposes. Since this acceptance is especially hard to achieve in computer-critical environments, such as medicine, we developed a software environment that allows for the development, integration, and user-centered evaluation of existing and new interaction techniques for their use in medical applications. This environment is equipped with an innovative message-passing functionality that provides the communication to and among application objects in 2D, 3D, and VR. Furthermore, the environment contains a component for user-adapted interaction and system support at runtime.
