Introduction: Various computer assisted medical procedures such as dental implant, orthodontic planning, face, jaw and cosmetic surgeries require automatic quantification and volumetric visualization of teeth. In this regard, segmentation is a major step. Material and Methods: In this paper, inspired by our previous experiences and considering the anatomical knowledge of teeth and jaws, we prop...

By recent progress in hardware, 3D visualization including VolumeRendering is adopted in various fields. Though CG is used in the atmospheric field, the scientists mainly use 2D visualization. So, we develop a 3D visualization system Gateau for atmospheric science. Gateau is a quick-look tool that enables them to observe 3D grid data with only a few instructions for the atmospheric scientists w...

Multimodality visualization aims at efficiently presenting integrated information obtained from different modalities, usually combining a functional modality (SPECT, PET, fMRI) with an anatomical modality (CT, MRI). This chapter presents a technique for 3D integrated visualization of SPECT and MR brain images, where MRI is used as a framework of reference for the display of the SPECT data. Meth...

Simulation modeling and visualization can substantially help in designing complex construction operations and in making optimal decisions where traditional methods prove ineffective or are unfeasible. However, there has been limited use of simulation in planning construction operations due to the unavailability of appropriate support tools that can provide users with a more realistic and compre...

Study of dynamical systems behavior can be very difficult. Therefore it is an advantage when someone can see how these systems perform in the 3D space. Visualization in 3D not only supports imagination but also helps to understand the physical nature of processes running as a reaction to the external forces applied to these systems. Using 3D visualization the performance of different types of d...

Due to the evolution of technologies and methods for realistic 3D reconstruction of objects, in many projects it can be found efficient ways to make research results in digital preservation available on the Internet. 3D visualization of cultural heritage is highlighted in this scenario, helping to expand research activities in this field by providing proper tools to allow for example, remote ac...

Students have trouble using and interpreting topographic maps. Experienced map-users identify patterns of contour lines representing topographic structures and visualize that information in 3D. Novices struggle with both recognizing 2D patterns and visualizing 3D structures from contour lines. In this study, the Pattern Identification group received instruction focused on identifying contour pa...

BACKGROUND Intravascular ultrasound (IVUS) is a standard imaging modality for identification of plaque formation in the coronary and peripheral arteries. Volumetric three-dimensional (3D) IVUS visualization provides a powerful tool to overcome the limited comprehensive information of 2D IVUS in terms of complex spatial distribution of arterial morphology and acoustic backscatter information. Co...

This paper explores the use of World Wide Web (WWW, or simply Web) as a means of designing and developing a toolkit, GeoV&A, for interactive 3D visualization and analysis of existing 2D Geographical Information System (GIS) data. The toolkit is mainly composed of two parts. One is a 3D visualization tool and the other is a 3D analysis tool, including profile creation, viewshed analysis, volumet...
