To meet the challenges of future digital atlas publication, a concept for an online 3D atlas platform (APS) has been developed. This framework should have the potential for combining interactive thematic cartography with real-time 3D atlas technology. As to system design, the APS will consist of extensible modules for spatial navigation, map visualization and information retrieval, integrated i...

With the emergence of open information spaces, e.g. digital libraries, advanced techniques for interactive visualization of complex and protected 3D documents are needed. This paper presents a new visualization concept which deals with the problems of complexity and security of digital 3D documents in open information spaces. A dynamic combination of remote and local 3D rendering is used to all...

In this paper methods for visualization and analysis of cerebral arteriovenous malformations (AVM) are presented. Spatiotemporal 4D magnetic resonance angiography (MRA) image datasets and 3D MRA datasets with high spatial resolution were acquired for analyzing AVMs. One of the main tasks is the combination of the information of these 3D and 4D MRA image sequences. Initially, in the 3D MRA datas...

1 [email protected], Laboratory for Computer Graphics and Artificial Intelligence 2 [email protected] Abstract Due to its monolithic nature, 3D visualization software integrated with legacy engineering applications contain every possible feature you might use – whether or not a user really wants them. With the advent of distributed objects and interpreted platform-independent languages suc...

Modeling, simulation and visualization of three-dimension complex bodies widely use mathematical model of curves and surfaces. The most important curves and surfaces for these purposes are curves and surfaces in Hermite and Bezier forms, splines and NURBS. Article is devoted to survey this way to use geometrical data in various computer graphics systems and adjacent fields. Simulation, modeling...

There is heightened optimism about the potential of 3D visualization software as an alternative learning resource in radiology education. The purpose of this study was to investigate the effect of 3D visualization software on students' learning of oral radiographic interpretation from 2D radiographic images. Fourth-year dental students underwent a learning intervention phase of radiographic int...

Visualization exists from the first known maps to today. Developments in computer science and technologies have resulted in arising new techniques besides maps for visualization of geographic data. Combining technologies such as image processing, computer graphics, animation, simulation, multimedia, and virtual reality, computers can help us present information in a new way so that patterns can...

Acknowledgements The work described in this thesis has been carried out from 1997 to 2002 at the department of Scientific Visualization of the Zuse Institute Berlin (ZIB). First of all, I would like to thank my tutors Prof. Dr. Peter Deuflhard and Hans-Christian Hege for the opportunity to work in this exciting interdisciplinary field. Without their constant support this work would not have bee...

For surgical planning, the exploration of 3D visualizations and 2D slice views is essential. However, the generation of visualizations which support the specific treatment decisions is very tedious. Therefore, the reuse of once designed visualizations for similar cases can strongly accelerate the process of surgical planning. We present a new technique that enables the easy reuse of both medica...

A general concept of 3D volumetric visualization systems is described based on 3D discrete voxel scenes (worlds) representation. Definitions of 3D discrete voxel scene (world) basic elements and main steps of the image synthesis algorithm are formulated. An algorithm for solving the problem of the voxelized world 3D image synthesis, intended for the systems of volumetric spatial visualization, ...
