-With the availability of OpenGL ES and low-power specialized graphics hardware, 3D graphics are increasingly incorporated into software for mobile devices. However, there is only a small body of research regarding effective user interfaces in this environment. The goal of this study is to analyze the effectiveness of several 3D mobile interfaces by conducting an experimental survey. Study part...

A number of software solutions for reconstructing 3D models from multi-view image sets have been released in recent years. Based on an unordered collection of photographs, most of these solutions extract 3D models using structure-from-motion (SFM) algorithms. In this work, we compare the resulting 3D models qualitatively and quantitatively. To achieve these objectives, we have developed differe...

In this thesis, a 3D approach to visualize software metrics is presented. Software metrics are attributes of a piece of software or its specification. They generally contain a set of multivariate time-series data and can be displayed, for example, as a Kiviat diagram consisting of axes and polylines. The aim of this work is to design a Win32 application that can load multivariate time-series da...

INTRODUCTION A novel realistic 3D virtual reality (VR) application has been developed to allow medical imaging students at Queensland University of Technology to practice radiographic techniques independently outside the usual radiography laboratory. METHODS A flexible agile development methodology was used to create the software rapidly and effectively. A 3D gaming environment and realistic ...

abtract background: in nuclear medicine, phantoms are mainly used to evaluate the overall performance of the imaging systems and practically there is no phantom exclusively designed for the evaluation of the software performance.  in this study the hoffman brain phantom was used for quantitative evaluation of reconstruction techniques. the phantom is modified to acquire tomographic and planar i...

Objective To establish a three-dimensional (3D) finite element (FE) model of ankylosing spondylitis (AS) kyphosis that is a digital platform for further studies. Methods A 30-year-old man with AS kyphosis underwent computed tomography transverse scanning from T1 to the sacrococcyx. The images were imported into Mimics® 17.0 software to establish a 3D model of the posterior spine, which was then...

he capability to develop prototype hardware systems is improving steadily as computer technology is dramatically enhancing design, fabrication processes, and tools. Designers now make extensive use of sophisticated 3D solid modeling programs to visualize design concepts, perform engineering analysis, and communicate detailed design data through networked file transfers. Numerically controlled c...

While the majority of patients receiving external beam radiation therapy treatment are planned by CT simulation, a significant number of them are still planned using conventional simulators for various reasons. The information-collection process in a conventional simulation is often fragmented and done with primitive tools. For example, in many institutions body contours are still acquired usin...

This paper describes an innovative learning environment, which integrates the Internet, 3D-CAD, and simulation tools in a web based learning system to ensure a better understanding of light perception in architectural space. The learning system comprises of a virtual laboratory, in which architectural planning examples can be represented three-dimensionally and be changed interactively. A devel...

The availability of intuitive, user-friendly, and specialized software to work with 3D models of cultural heritage artefacts is as important as the availability of low-cost and robust data acquisition techniques for the adoption of digitized 3D models in cultural heritage research. The number of available high-quality digitized artefacts increases rapidly with the advent of low-cost 3D scanning...
