Exploring a multidimensional dataset with visualization requires to transition between points of view. In order to enable users to understand transitions, visualization can employ progressive 3D rotations. However, existing implementations of progressive 3D rotation exhibit some perception problems with visualization of cluttered scene. In this paper, we present a first experiment showing how e...

The importance of correctly determining the requirements of a system at the very beginning of the development process it is a well known fact. Experience shows that the incorrect definition of the requirements leads to the development of deficient systems, increases the cost of its development or even causes projects to fail. Therefore it is crucial for the clients to verify that the planned sy...

With increasingly available stereoscopic technology and techniques, it is interesting to investigate new ways of representing information using stereoscopy. Within this context a user study was performed to compare if it is worthwhile to use 3D map presentations over 2D, and to identify how much a 3D stereoscopic map can be slanted without losing the perception of information. Two different vis...

CityGML provides an effective approach to the sharing and inoperability of 3D GIS spatial data. However, due to the large amount of data, CityGML’s resolving, transferring, and rendering processes during visualization are inefficient in a standalone system, causing considerable delays in viewing the information of large 3D maps for users. The cloud computing technique is introduced to address t...

The Web has become a new medium which can display geographical information in rich forms and offer user-friendly interfaces. One of the promising trends in current Geographical Information System (GIS) is the use of Web 3D technology, especially VRML (Virtual Reality Modeling language). As one of the most fundamental geographical information, terrain information is often presented as the base f...

Spatially varying sensing (foveation) was first used as a means for image compression in our past research [1]. In this report we extend previous work by us to address the advantages of foveation in improving the performance of interactive 3D visualization over bandwidth limited channels, such as the Internet. We develop an algorithm that is implemented in JAVA3D. The method combines foveating ...

The purpose of this study is to determine which 3D viewers should be used for the display of interactive graphic engineering documents, so that the visualization and manipulation of 3D models provide useful support to students of industrial engineering (mechanical, organizational, electronic engineering, etc). The technical features of 26 3D visualization software programmes (viewers, publisher...

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 poster presents a new visualization concept and software architecture which deal with the problems of complexity and security of digital 3D documents in open information spaces. A dynamic combination of remote and local 3...

Your SPH simulation can either be 2D or 3D. As with all other projects, computation should be done in GLSL, however for the 3D visualization we only require point sprites (for 2D) or spheres (for 3D). You do not need to compute an explicit uid surface for this project a particle visualization is su cient. However, we encourage you to color the particles or spheres according to some metric (ie. ...

Several studies (e.g. Kerr, 1987; 1993; Diwadkar, Carpenter & Just, 2000) have asked participants to report the final location of a point after imaginary moves through 2D and 3D arrays. The results suggest that visualizing 3D space is inherently more difficult than 2D visualization, and may even use different brain mechanisms. However, 2D and 3D trials were presented in separate blocks, so part...
