    Through interaction with surroundings, the fluids may change their properties such as shapes, temperature vastly, and the same would happen to the surroundings simultaneously. On the other hand, different surroundings characterize different interactions, and may change the shapes and motions of the fluids in different ways. Therefore, it is of importance in physically-based simulation of fluids to... View full abstract»

    We have proposed and implemented function-based extensions of X3D and its predecessor VRML which allow for defining time-dependent geometric shapes, their appearance and transformations with analytically defined parametric, implicit and explicit functions. The function-defined shapes can be used together with the standard X3D and VRML shapes. Besides defining shapes by analytical functions, we hav... View full abstract»

    Web-based mixed reality (MR) that combines remote real objects with a virtual environment to form a realistic 3D MR space has received much interest in cyberworlds. This paper introduces a novel method of integrating a live video object that is taken by multiple fixed cameras in a remote natural environment into a MR space. Using the captured live video frames, the view of the remote object corres... View full abstract»

    In addition to established methods, the treatment of mental disorders using virtual reality exposure therapy is becoming commonplace. We present an approach, which extends this concept in three ways: (1) the provision of maximum control for the therapist over the exposure environment, (2) the inclusion of different media and mediation elements in the virtuality continuum in mixed reality, and (3) ...

    Machining process simulation and monitoring have been actively researched. However, technologies developed in these two areas have not really been employed in the industries. Human operators are still the vital factor in any manufacturing processes. Augmented reality (AR), a recently developed technology that seamlessly combines virtual information and the real environment, has been applied in var... View full abstract»

    We have developed an automatic composition system for ballet choreographies by using 3DCG animation. Our goal is to develop some useful tools in dance education such as creation-support system for ballet teachers and self-study system for students. The algorithm for automatic composition was integrated to create utilitarian choreographies. As a result of an evaluation test, we verified that the cr... View full abstract»

    We propose a mechanism by means of which a user with little expertise of programming can easily produce custom-made virtual scenes. A typical scene comprises virtual entities that take decisions in real time in response of perceived environmental changes. The actions performed lead to the fulfillment of one or more goals specified by the scenarist. We have developed an open agent-oriented system. ... View full abstract»

    The paper presents an implementation of virtual studio visualization tools in the decorative arts museum collections. Live DV video 2D images are embedded in a Java 3D environment (a 3D canvass). The virtual studio implemented includes navigation control of the real camera with a robot support controlled with a joystick. Navigation within the Java 3D virtual environment includes the real camera mo... View full abstract»

    Currently, in the development of business applications, difficulties occasionally arise between the customer side and the supplier side, causing delays and higher development costs. To deal with this, we propose a new development method for business applications to validate them by invariant preservation based on equivalence relations. We have realized it by designing an algebraic expression calle... View full abstract»

    Recognized Web data stream as a source of new business creation and proposed a contextual business model that creates business value by converting the disparate data stream into meaningful context and serves its contextual customers. In this paper, we develop our model further and exemplify with an application that is currently in progress. Our contribution is two fold: use of affordance as the ba... View full abstract»

    The geospatial category of simulations is used to show how origin centric techniques can solve a number of accuracy related problems common to 3D computer graphics applications. Previous work identified how poor understanding of floating point related issues lead to performance, architectural and accuracy problems. This paper extends that work by including time error minimisation, lazy evaluation ... View full abstract»

    Considerable efforts are needed to construct a virtual environment for military operations on urbanized terrain (MOUT). The models of various objects used in one application are often specifically designed for that application, thus are not generally suitable for other applications. We often have to rebuild many object models for a new simulation setup, which is very tedious and time consuming. To... View full abstract»

    Creating 3D geographical simulations have been useful to many applications of geological information. Generally, typical CG simulations cannot properly and accurately represent the multilayer geographical data, due to the lack of ability to display the relations or connections between each soil layer. Also, there are errors in the position of soil layers, and classification of soil layers which do... View full abstract»

    Cooperative knowledge spaces have a high potential to improve eLTR (eLearning, eTeaching and eResearch) at universities. Since there are few implementations deployed, notably in the fields of mathematics, natural sciences, and engineering, we propose a concept for field-specific knowledge spaces for those disciplines -"ViCToR"-Spaces (virtual cooperation in teaching and research for mathematics, n...

    In this paper, we studied the relationship between the accuracy of the dead reckoning data and the update interval in a distributed virtual environment (DVE). We have already shown that numerical analysis can be applied to the dead reckoning data between frames using parametrics calculated from the data over the last several frames based on polynomial models. Based on the above polynomial models, ... View full abstract»

    Distributed virtual environments (DVEs) allow many simultaneous human users to interact with each other in shared, 3D virtual worlds. The interactivity of a DVE is of crucial importance, as its success greatly depends on users' perceptions when interacting within the virtual world. In this paper, different from traditional application-centric approaches like dead reckoning, we propose a network-ce... View full abstract»
