    A prototype system for immersive music editing and playing has been developed. The system enables one to edit musical notes and control playing in an immersive virtual environment using multimodal interfaces. The immersive virtual reality is suitable as a natural interface for many people. One can manipulate musical notes by hand, learn to read a musical score and understand the relationship betwe...

    A scan-line algorithm uses a one-dimensional set operation instead of a depth comparison to find a visible surface of the object shape defined by constructive solid geometry (CSG). Interactive solid modelers employing a scan-line algorithm require considerable computing time in repeated construction and destruction of parts of the CSG object models during the design process. We discuss three steps... View full abstract»

    Rational Bezier curves provide flexibility in curve design. The goal of this paper is to perform error analysis of Farin's (1983, 1986) algorithm for the evaluation of these curves. It is shown that a similar error analysis can be applied for the algorithms in rational spaces obtained from spaces admitting shape preserving representations View full abstract»

    This paper argues for the creation of a software repository for research and education in information visualization (IV). It starts with an introduction and overview of IV online resources and software repositories. Next, we introduce the code repository that we have created and demonstrate how it was used in the IV course which one of the authors teaches. Sample implementations by students are pr...

    Visualization of large urban complexes on the Web is a highly demanding task both from the networking and computational point of view. The whole three-dimensional model of a city is mostly too big to be downloaded in a reasonable time and to be stored in a memory of commonly used computers. This paper presents a scalable approach for subdividing an urban model into smaller parts. Dynamic loading a... View full abstract»

    Visualisation is generally considered to be a problem in structural design. Being an iterative process, structural design is time consuming for engineers, and results are difficult for clients to visualize. Current numerical methods have slow dynamic visualisation capability, which is usually separate from the calculation phase. The paper investigates whether an analogue virtual reality (VR) model...

  • Interactive metamorphic visuals: exploring polyhedral relationships

    Publication Year: 2001 , Page(s): 483 - 488
    Request Permissions | Click to expandAbstract | PDF file iconPDF (584 KB) |  | HTML iconHTML  

    The paper presents an interactive visualization tool, Archimedean Kaleidoscope (AK), aimed at supporting a learner's exploration of polyhedra. AK uses metamorphosis as a technique to help support the learner's mental construction of relationships among different polyhedra. AK uses the symmetric nature of the platonic solids as the foundation for exploring the way in which polyhedra are related. Th... View full abstract»

    Many professional educators who instruct courses in computer graphics programs have been mindful of teaching students those subjects required to become successful graduates in their field of study. However, many teachers and professors believe that we have not ensured that their students have always been properly prepared to deal with ethical issues associated with the work they will do in industr...

    We present extensions to an approach for rendering time-varying data based on the shear-warp factorisation. The change detection technique is adapted to process Poisson distributed datasets, a modified block differencing technique that decreases the change detection errors is presented along with a modification of the original run-length encoding method which allows better spatial compression for ...

    Presents shape control methods for cubic B-spline and NURBS curves by the modification of their knot values and by the simultaneous modification of weights and knots. Theoretical aspects of knot modification are also discussed, concerning the paths of points on a curve and the existence of an envelope for the family of curves resulting from a knot modification for curves of degree k View full abstract»

    Many non-speaking people use augmentative and alternative communication (AAC) systems to assist them to communicate with other people. Access to an AAC system is generally slow for its user, who may have other disabilities as well as being non-speaking. An AAC system can contain stored words, messages and stories for use in communication, and there can be a large quantity of such information for t... View full abstract»

    Generally, in the field of industrial design, the measurement data of a clay model are faired, and a 3D model is made in CAD. However, it is a problem that this fairing work takes a long time and requires a great deal of labor. We propose an automatic curve fairing system for the application to reverse engineering technology. The system is constructed by the following five steps. (1) Key-line data... View full abstract»

    Examining a program's state during execution is of major importance for software developers when analyzing an application for performance tuning or error detection. This demand for suitable analysis tools is further pushed by parallel and distributed programs, which process huge amounts of complex data. A solution to this problem is offered by visualization, such that even a large amount of data c... View full abstract»

  • Adaptive fairing of surface meshes by geometric diffusion

    Publication Year: 2001 , Page(s): 731 - 737

    In triangulated surface meshes, there are often very noticeable size variances (the vertices are distributed unevenly). The presented noise of such surface meshes is therefore composite of vast frequencies. We solve a diffusion partial differential equation numerically for noise removal of arbitrary triangular manifolds using an adaptive time discretization. The proposed approach is simple and is ...

    Production planning is difficult not just because of the intricate relationships between the myriads of parameters, but also the dynamic nature of changes in the decision making environment. Good visualization tools for production planning are rare. Production planning is not merely an optimization problem. The possibility of making incremental manual changes will allow the planner to be more resp... View full abstract»

    A number of researchers have shown that scientific visualization provides enhanced understanding in domains with significant information complexity. Unfortunately, the task of creating engineering visualization, especially immersive visualization, is highly complex and lacks high-level tools that would simplify the development process.

    The marching cubes algorithm of W.E. Lorensen and H.E. Cline (1987) is a method that is used frequently in 3D object visualisation. The underlying concept of the technique is to form piecewise planar approximations to surfaces, for which pre-determined normals are used for shading purposes. It should be noted that these approximations are precisely as accurate as the data given; there is no loss i... View full abstract»

    Our goal is to deal with a non rigid surface, for example lubricant around a ball, interfaces between two fluids and so on. We then first describe how to approximate a movement and then how to interpolate such approximating functions. Finally we present two alternatives, global or local interpolation of the movements View full abstract»

    Finding a previously visited page during Web navigation is a very common and important process. Although most commercial browsers incorporate a history mechanism, when accessing pages that were recently visited, users still rely mainly on the “Back” button. In this paper, we studied the effectiveness of visually enhanced history browser mechanisms on Web navigation. We used three diffe... View full abstract»
