Accurate understanding and visualization of the mechanisms of cardiac arrhythmias originating from a complex 3D substrate are a prerequisite for successful treatment of such disorders. Nonfluoroscopic cardiac mapping systems are designed to provide the required spatial anatomical information in combination with local electrical information. During recent years, the EnSite system, with its EnSit...

3D visualization was established for noninvasive evaluation of neurovascular compression syndromes. MR-CISS (constructive interference in the steady state) is the most potent image source to depict neurovascular details. The purpose of this article is the conceptual view over the established technique of 3D visualization in the topography of aneurysms in the posterior circulation in relation to...

The object oriented Visualization Toolkit (VTK) is widely used for scientific visualization. VTK is a visualization library that provides functions for presenting 3D data. Interaction with the visualized data is done by mouse and keyboard. Support for three-dimensional and multimodal input is non-existent. This paper describes VR-VTK: a multimodal interface to VTK on a desktop virtual environme...

Three Dimensional (3D) image visualization is one of the important processes that extract information from a given single image. A robust algorithm is proposed to estimate the surface rendering of a single-view image. Firstly, the angiography image is enhanced and then conduct the segmented image into partitioning process in which the image is divided into homogeneous regions using adaptive K-m...

Our research in institute is oriented on high performance computing like GRID and Cloud computing. A lot of international projects oriented on main research or in energy execution and in natural disasters damages execution utilize the HPC (High Performance Computing) as is grid or cloud computing. Within such solution raises requirement of visualization service for presentation of the intermedi...

We present a rigorous formal but transparent specification of the semantics of a generic simulation-based 3D animation framework. Our system combines a SystemC simulation kernel with a virtual visualization machine for 3D animation. The semantics of the simulator and the virtual visualization machine are formally defined by means of distributed Abstract State Machine (ASMs) rules. The ASM rules...

High accuracy and quality of photorealistic 3D modeling and visualization of close range objects can be achieved only with 3D scenes generated on the basis of photogrammetric data. Images and geometrical data for testing our original application were obtained from complex photogrammetric architectural object restitution. The object was recorded with a digital camera Kodak DC 4800 with 3.1 Megap...

There is ample evidence that instruction in spatial visualization skills is effective in improving outcomes for engineering students. Research conducted since the early 1990’s has proven that spatial visualization practice and training leads to better grades in engineering graphics and in most other engineering coursework. Other studies demonstrate that improved 3D visualization skills improve ...

With 3D information space we denote a three-dimensional visualization that contains 2D visualizations and puts them in a semantic context. In this paper, we show how Mixed Reality (MR) can be exploited as a technology in order to realize better interaction in a 3D information space and, as a result, to develop new interactive visualization techniques. Here, the real space is used as a metaphor ...

This study evaluated the effects of the light curing methods and resin composite composition on composite polymerization contraction behavior and resin composite adaptation to the cavity wall using μCT-3D visualization analysis and dye penetration test. Cylindrical cavities were restored using Clearfil tri-S Bond ND Quick adhesive and filled with Clearfil AP-X or Clearfil Photo Bright composite...
