The ability to perform fast, accurate, high-resolution visualization is fundamental to improving our understanding of anatomical data. As the volumes of data increase from improvements in scanning technology, the methods applied to visualization must evolve. In this paper, we address the interactive display of data from high-resolution magnetic resonance imaging scanning of a rabbit heart and subsequent histological imaging. We describe a visualization environment involving a tiled liquid crystal display panel display wall and associated software, which provides an interactive and intuitive user interface. The oView software is an OpenGL application that is written for the VR Juggler environment. This environment abstracts displays and devices away from the application itself, aiding portability between different systems, from desktop PCs to multi-tiled display walls. Portability between display walls has been demonstrated through its use on walls at the universities of both Leeds and Oxford. We discuss important factors to be considered for interactive two-dimensional display of large three-dimensional datasets, including the use of intuitive input devices and level of detail aspects.

Visualization is an efficient technology to display the information and the inherent properties of geographic data, mine the regularity and development trends between the data and give researchers the unexpected insight. As the using and distribution of visualization resources exists imbalance, in order to meet the need of Geography Science, this paper presented a Grid Computing-based High-performance Visualization Environment. This environment is based on the mature grid middleware, CGSP to achieve the Grid integration and sharing of the geo science visualization software. A demonstration application was discussed to verify the visualization environment. The environment would achieve the visualization of the massive geo-spatial data efficiently and expediently, enhance the collaborative research to solve problems and improve their research environment.

An increasing number of types of spatial data is possible to display and operate using only technical means of web services and a standard browser, without the need to install GIS or CAD systems. One of these types of data is data obtained with using active methods of remote sensing (as a rule, they are point clouds), full-fledged work with which 3–4 years ago was possible only on high-performance computers and specialized software. The existing web technologies allow not only displaying point clouds, but also interactively interacting with them - to perform measurements, customize display styles, combine with spatial data of other types. The purpose of the article is to form criteria and analyze the performance of software tools for creating web services for visualizing data obtained with using active methods of remote sensing. For practical testing of the selected software and analysis according to the formulated system of criteria groups, several files containing point clouds from open sources were used. The research was carried out with using the software libraries Three.js, Deck.gl, Plas.io, Potree, CesiumJS and Blend4Web. Based on the testing results, summary tables of performance and functionality were formed. The obtained results demonstrate that in terms of performance, visualization tools, basic functions for designing and analyzing point clouds, modern web services are not inferior to specialized desktop software.

Structural appraisal of thin film magnetic media is very important because their magnetic characters such as magnetic hysteresis and recording behaviors are drastically altered by the grain structure of the film. However, in general, the surface of thin film magnetic media of magnetic recording disk which is process completed is protected by several-nm thick sputtered carbon. Therefore, high-resolution observation of a cross-sectional plane of a disk is strongly required to see the fine structure of the thin film magnetic media. Additionally, observation of the top protection film is also very important in this field.Recently, several different process-completed magnetic disks were examined with a UHR-SEM, the JEOL JSM 890, which consisted of a field emission gun and a high-performance immerse lens. The disks were cut into approximately 10-mm squares, the bottom of these pieces were carved into more than half of the total thickness of the disks, and they were bent. There were many cracks on the bent disks. When these disks were observed with the UHR-SEM, it was very difficult to observe the fine structure of thin film magnetic media which appeared on the cracks, because of a very heavy contamination on the observing area.

Modern technologies, which provide fast and accurate acquisition of high-resolution spatial data, have found widespread application in the monitoring of coastal processes. This paper reports the results of four years’ monitoring of a huge deflation/blowout/wind-scour basin dynamics at the Vistula Spit (southeast coast of the Baltic Sea). Information about the volume and size dynamics together with deflation/accumulation schemes and 3D elevation maps is presented. Basing on the obtained results, forecast of the deflation basin dynamics for 2016 was proposed. This paper implements the Terrestrial Laserscanning (TLS) method to the coastal processes investigation and demonstrates its high potential in this field.
