For the sharing integration and 3D visualization of multi-source, heterogeneous, widespread distribution information, we propose a three-dimensional integrative visualization architecture based on SOA and virtual globe. The paper elaborates on the overall architecture and the relative fundamental technologies. Then studies the key technologies, such as the unified 3D integration of 2D GIService...

In medical imaging, many applications require visualization and/or analysis of three-dimensional (3D) objects (e.g. organs). At same time, object definition often requires considerable user assistance. In this process, objects are usually defined in an iterative way and their visualization during the process is very important to guide the user's actions for the next iteration. The usual procedu...

In this research, we present our MetaViz project that was initiated to investigate software visualization issues in the context of novel modeling and visualization techniques. The focus of our research is the visualization of software structures and their dynamic behavior using 3D visualization techniques. Rather than applying traditional 2D visualization techniques and transfer these to the 3D...

This paper deals with the problem of visualization of 3D scenes and navigation in them on mobile devices. A visualization technique that enables visualization and annotation of objects in a 3D scene on mobile devices is presented. This technique is based on transformation of the 3D scene to a 2.5D representation in 2D vector graphic. The input of the 3D scene is given in the VRML format and the...

Recent improvement of high-end GPUs has made it possible to perform real-time 3D visualization such as volume rendering and 3D contour plot for scientific data locally. A web browser based remote 3D visualization by visualization servers is attractive, but data transfer overhead prevents from performing interactive operations. We propose an interactive remote 3D visualization model by live stre...

BACKGROUND Converting the two-dimensional (2D) cross-sectional photographs into an intuitive three-dimensional (3D) model is a basic task for medical imaging data for auxiliary disease-linked diagnosis purpose. METHODS Reconstruction and visualization process of gastrointestinal cross-sectional photographs includes image preparation, image registration, image segmentation, 3D surface-renderin...

Flow visualization in 3D is challenging due to perceptual problems such as occlusion, lack of directional cues, lack of depth cues, and visual complexity. In this paper we present an interaction technique that addresses these special problems for 3D flow visualization. The feature we present, a streamrunner, gives the user interactive control over the evolution of streamlines from the time they...

PURPOSE Three-dimensional (3D) magnetic resonance phase contrast imaging (PC-MRI) allows non-invasive diagnosis of pulmonary hypertension (PH) and estimation of elevated mean pulmonary arterial pressure (mPAP) based on vortical motion of blood in the main pulmonary artery. The purpose of the present study was to compare the presence and duration of PH-associated vortices derived from different ...
