Most systems that support visual interaction with 3D models use shape representations based on triangle meshes. The
size of these representations imposes limits on applications for which complex 3D models must be accessed remotely. Techniques for
simplifying and compressing 3D models reduce the transmission time. Multiresolution formats provide quick access to a crude model
and then refine it progressively. Unfortunately, compared to the best nonprogressive compression methods, previously proposed
progressive refinement techniques impose a significant overhead when the full resolution model must be downloaded. The CPM
(Compressed Progressive Meshes) approach proposed here eliminates this overhead. It uses a new technique, which refines the
topology of the mesh in batches, which each increase the number of vertices by up to 50 percent. Less than an amortized total of 4 bits
per triangle encode where and how the topological refinements should be applied. We estimate the position of new vertices from the
positions of their topological neighbors in the less refined mesh using a new estimator that leads to representations of vertex
coordinates that are 50 percent more compact than previously reported progressive geometry compression techniques.

This paper describes the result of the interdisciplinary cooperation of traumatologists of the Berufsgenossenschaftliche Unfallklinik (BGU) in Frankfurt am Main and a team of computergraphics scientists of the Fraunhofer Institute for computergraphics in Darmstadt. We have developed a highly interactive training simulator system by means of computergraphics and virtual reality techniques.
Stylized tubes are an established visualization primitive for line data as encountered in many scientific fields, ranging from characteristic lines in flow fields, fiber tracks reconstructed from diffusion tensor imag...

This paper describes a system for investigating molecule data. By means of combined Virtual Environment and Scientific visualization techniques it allows for immersive exploration of individual molecules as well as for investigation of docking behaviour between two molecules. Special emphasis is put on good interaction (simultaneous operation of two input devices with 6 degrees of freedom each, virtual menus), on fast rendering of large molecules in high quality (level of detail, fast rendering of spheres, utilization of multiple rendering pipelines, sorted triangle strips for transparent surfaces), and on other perceptual issues (e.g. judgement of position and size of molecules by shadows). The techniques which were realized for this system may also be used in other applications like assembly tasks, virtual material testing, etc. (C) 1996 Elsevier Science Ltd

The need for courses on medical graphics, especially in real-time volume graphics, has increased. In order for students to develop skills sufficient to work on independent studies, or Bachelor's or Master's Theses, they will need 3 courses on computergraphics: course I teaches basic computergraphics according to the rendering pipeline;course II extends into advanced rendering and modeling algorithms and lays the foundation for computer-generated visualization;course III can then use these foundations to extend into medical graphics.
In computergraphics one is often concerned with representing 3D objects on 2D displays, which provide often only a limited display field of view (DFOV) to the observer. Usually, planar geometric projections, in parti...
