Cardiac angiography using multiple detector row computerized tomography (MDCT) scanners provides 3D data concerning the heart and, in particular, the left ventricle (LV), for different cardiac phases along one cardiac cycle. Exploring this data for LV function analysis is not an easy task, given the amount of data and time involved in segmenting (or revising results provided by automatic segmentation methods) up to 12 cardiac phases. CardioAnalyser, a tool for 4D LV segmentation from MDCT data which provides a protocol to help perform LV segmentation of all cardiac phases available is presented. It uses an automatic segmentation algorithm along with a procedure which guides the user through the process. Its main goal is to reuse as much information as possible from one cardiac phase to the next in order to reduce segmentation time and the amount of user interaction.

Conventionally, a grid generator requires either an explicit or implicit description about the boundary vertices, boundary lines and boundary faces to define the geometry. In 2006, the author has developed the Interactive Web based Grid Geometry Construction process [1] to create and generate 2D ubiquitous platform independent, highly scalable, paintbrush, pixel and vector free geometry art. In 2008, she has established a new paradigm -- basically, a fundamental medium for visualization, development, creation and delivery tool for generating grid geometry art and beyond. With exceptions, the result is instantly Web-enabled. She demonstrates the results of the deployment of this image editor free tool by presenting an array of instant conceptualization and artistic realization of an “image” as an arrangement of an uniform m x n grid of colored cells formed within a set of finite orthogonal grids. Beyond which, this paper presents a wide-ranging display of non-orthogonal and soft-edged image free2)2) images.
通常，网格生成器需要一个关于边界顶点、边界线和边界面的显式或隐式描述来定义几何。2006年，作者开发了基于Web的Grid Geometry Construction process[1]，用于创建和生成2D无所不在的、独立于平台的、高度可扩展的、无画笔、无像素和无矢量的几何艺术。在2008年，她建立了一个新的范式——基本上，一个基本的媒介，可视化，开发，创造和交付工具，用于生成网格几何艺术和超越。除例外情况外，结果是立即启用web。她展示了使用这个免费图像编辑器工具的结果，通过展示一系列即时概念化和艺术实现的“图像”，作为在一组有限的正交网格中形成的均匀m x n网格的彩色细胞的排列。除此之外，本文还介绍了非正交和软边缘图像自由的广泛显示。

Visualization of graphs containing many nodes and edges efficiently is quite challenging since representations generally suffer from visual clutter induced by the large amount of edge crossings and node-edge overlaps. That problem becomes even more important when nodes positions are fixed, such as in geography were nodes positions are set according to geographical coordinates. Edge bundling techniques can help to solve this issue by visually merging edges along common routes but it can also help to reveal high-level edge patterns in the network and therefore to understand its overall organization. In this paper, we present a generalization of [18] to reduce the clutter in a 3D representation by routing edges into bundles as well as a GPU-based rendering method to emphasize bundles densities while preserving edge color. To visualize geographical networks in the context of the globe, we also provide a new technique allowing to bundle edges around and not across it.

The orientation towards data in arts, humanities and pop culture in recent years brings a renewed interest in realism and iconoclasm. The various APIs (Application programming interfaces) and mashups that are employed in these traditionally “qualitative” disciplines offer tools for creative and often critical interpretations. Data are becoming means of a critical distance to the visual and media saturated world that bring whole new perspective on our everyday life and reality. These emerging critical and visual practices define a realism based on data rather than on human perception, reason or some strong ontological theses. This data oriented realism does not simply represent reality but performs the modern processes of its construction with an almost iconoclastic fervor. It offers a distance from the power and seduction of the (digital) image and asks questions about their conditions of possibility, methods of gathering and the various possibilities of their representation. Visualization of various data in the form of popular user generated mashups, serious art visualizations and new digital methods in humanities create a tension between the new forms of iconoclastic realism and the more playful dada collage techniques that are satirical and rather than realist and emancipatory rather than iconoclastic. The use of visualizations in art, humanities and online popular culture (cyberculture) is defined by this tension between data realism to dada “aggregations”.

This paper describes the application of Medieval and Renaissance color theory to the computer graphic rendering of molecular models. In particular, Alberti’s and Cennini’s color theories were employed to render shaded geometric primitives such as cylinders and spheres that are the components of traditional ball-and-stick and space filling molecular models. These results were compared with standard rendering based on the OpenGL API or through ray tracing. It is found that by implementing Alberti’s and Cennini’s color theories as color maps within a simple chemical illustration program it is possible to create molecular imagery comparable to contemporary computer graphics schemes.

Accessing personal and online music libraries with thousands of songs has become an everyday activity. Instead of textual lists, the libraries can also be accessed using graphical visualizations such as adaptive avatars. To develop the idea further, we designed 17 stereotypical avatars representing different musical genres. To study how well the avatars were recognized, an online questionnaire with 71 participants was arranged. This paper discusses the design of the avatars in more detail, explains which musical genres were selected for the study and why, and presents the results of the questionnaire.

Communication during the design process has a substantial role because; it exchanges messages and conveys ideas to people with different skills and interests. Also, the development of high quality 3D modelling, photo rendering and VR software has shifted the way we communicate architecture, from a conventional one to a digital format and so, provided us with another way for the communication of information, the visualisation of processes and the creative expression of ideas. This paper investigates the impact that Immersive Virtual Reality technology can have on visualisation of a design review scenario in construction, which was developed during the course of the European CoSpaces project and the potential of such technologies to alter the way enterprises work.

This paper presents a system for visualizing the information contained in the text of a web page. The goal of the visualization is to help the users better and faster understand the text on a web page and/or find related content on the internet. These visualizations are possible due to the use of text mining, natural language processing and semantic web technologies. Our system tries to make these technologies instantly accessible to a wide variety of users reading a wide variety of web pages. This high coverage of both users and content can be achieved because the system is implemented as an extension to Firefox, one of the most popular browsers, and because the visualizations are computed on the fly for any page the user happens to be reading at a given moment.

Information spaces such the WWW are the most challenging type of space that many people navigate during everyday life. Unlike the real world, there are no effective maps of information spaces, so people are forced to rely on search engines which are only suited to some types of retrieval task. This paper describes a new method for creating maps of information spaces, called INSPIRE. The INSPIRE engine is a tree drawing algorithm that uses a city metaphor, comprised of streets and buildings, and generates maps entirely automatically from webcrawl data. A technical evaluation was carried out using data from 112 universities, which had up to 485, 775 pages on their websites. Although they take longer to compute than radial layouts (e.g., the Bubble Tree), INSPIRE maps are much more compact. INSPIRE maps also have desirable aesthetic properties of being orthogonal, preserving symmetry between identical subtrees and being planar.
