    Models for visualization are important, helping the developer and user to understand the visualization process; to follow the connections and the data paths through the system; and to reference and compare the functionality and the limitations of different systems or techniques. Display models specifically classify the data by what type of output can be created. Bertin, J. (1962) described a symbo... View full abstract»

    During a civil engineering construction process many types of professionals are involved, such as engineers, constructors, designers, clients and so forth. To provide mutual understanding among construction workers and to unify their ideas, the creation of an effective presentation is necessary. In addition, the construction process has to work relatively in harmony with the situation of the const... View full abstract»

    The paper investigates human cognitive performance when information is presented via augmented reality (AR) and overlaid upon a primary display. Initial results support traditional experimental paradigms of human memory (G.A. Miller, 1956) and comprehension of information (C.D. Wickens, 1992), and have been used to compare AR and standard display formats when used in isolation. Results from these ... View full abstract»

    As distinct from virtual reality, which seeks to immerse the user in a fully synthetic world, computer-augmented reality systems supplement sensory input with computer-generated information. The principle has, for a number of years, been employed in the head-up display systems used by military pilots and usually comprises an optical display arrangement based on part-silvered mirrors that reflect c...

    Architects and other designers use diagrams to visualize the process of product analysis and synthesis. The paper outlines a new pictorial representation tool that helps designers visualize the process of composing and classifying their final products. Finite state automata (FSAs) are used in the context of formal languages as recognition devices. In this sense, they complement the synthetic devic... View full abstract»

    The aim of occlusion culling is to cull away a significant amount of invisible primitives at different viewpoints. We present two algorithms to improve occlusion culling for a highly occluded virtual environment. The first algorithm is used in the pre-processing stage. It considers the combined gain and cost of occluders to select an optimal set of occluders, called minimum occluder set, for each ... View full abstract»

    Architectural designs are translated into buildings using the documentation language. Gaps invariably exist between what is documented and what is built. Once a building is complete, its construction is largely concealed and it becomes difficult to compare the drawn details with the built details. This difficulty is compounded by the abstract nature of traditional architects' orthographic drawings... View full abstract»
