    We introduce a matrix based 'visual reference system model' for architectural heritage. The system consists of multilayered Web pages containing visual and textual data about architectural periods, styles and elements. The structure of the system may be adapted to various architectural concepts and periods. Yet, it is flexible enough to be limited down to a specific period or architect only. The m...

    For visual perception of 3D models, shading plays one of the major roles. The shading quality of level-of-detail models is limited generally because existing LOD algorithms assume a conceptually smooth surface. A complex mesh, however, is likely to have conceptually smooth and angular parts. We introduce an extension to the progressive mesh LOD approach that efficiently handles triangle meshes wit...

    We propose a new 3D visualization tool for hierarchical information. A 2D visualization tool for hierarchical information called treemap has already been proposed by Ben Shneiderman, et al. in 1992. In general, hierarchical information is represented as a tree structure. Treemap hierarchically lays out each node as a bounding box whose size is the same as the specific weight or attribute value of ... View full abstract»

    We present a fast focus+context viewing technique for the navigation of classical hierarchical layouts. In these layout techniques, only one dimension is considerably important to the visualization. Based on this property, we consider only one dimension of distortion of views for browsing the hierarchical structures. We firstly introduce briefly some information visualization techniques. We then d... View full abstract»

    An essential characteristic of design communication is the need to talk about things (objects and concepts). We concern the development of a practical method to assist the iterative development of computer-mediated communication (CMC) systems that support talk by designers working co-operatively over distance. Previous approaches to the study of CMC systems limit the extent to which the value of n... View full abstract»

    Diffusion-limited aggregation (DLA) is a model of fractal growth. Computer models can simulate the fast aggregation of millions of particles. We propose a modified version of DLA, called semantically modified DLA (SM-DLA), for visualizing large-scale networks. SM-DLA introduces similarity measures between particles so that instead of attaching to the nearest particle in the aggregation, a new part... View full abstract»

    Natural science is where the objective and the subjective meet. When we build data collections, we want them to reflect the objective relations inherent in nature, but also classify these collections, adding subjective relations between data objects. Sometimes these two approaches conflict. We present two examples of blending objective and subjective relations in a single data collection, and disc... View full abstract»

    A large amount of strategically relevant business information is contained in unstructured texts. While information brokering approaches are used to contextualize such documents and to generate metadata, text mining is used to explore large document spaces. So far, little attention has been paid on a value-adding combination of these technologies. We show how metadata and documents can be compleme... View full abstract»

    We present a simple method for visual simulation of refraction phenomena in the Earth's atmosphere. The method divides the atmosphere into a set of spherical layers and the rays are approximated by circular arcs within the layers. The curvature of arcs is related to the variations of the refractive index. The path of the ray through the atmosphere is found by intersecting the circular arcs with th... View full abstract»
