    Visualisation in the field of dentistry has not, thus far, reached the same development as other medical fields. Potential applications of visualisation techniques in this area, however, are many, ranging from educational displays to training for delicate procedures. This paper reports on the investigation of techniques for handling 3D models of teeth, aiming at the investigation of dental structu... View full abstract»

  • Curve fitting and design by optimal control methods

    Publication Year: 1998, Page(s):108 - 113
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (200 KB)

    The theory of optimal control is introduced as a new approach for handling curve fitting and design problems. Optimal control provides a uniform formal framework for stating and solving multiple problems in computer-aided geometric design (CAGD). As a result, new classes of curves are defined and known problems are analyzed from a new viewpoint. Often, families of curves which are defined by a min... View full abstract»

    A computer visualisation application has been presented for the fuzzy evaluation of windscreen wiper systems which must satisfy several requirements. Some requirements are modelled by fuzzy sets, and a compensating arithmetic mean is utilised for computing the overall performance. A computer animation of the wiper mechanism motion and rainfall is shown, which enables experts, drivers and passenger... View full abstract»

    Curative radiotherapy of localised cancer delivers discrete doses of radiation to diseased tissue over many days. Computer driven multileaf collimators now closely conform radiation dose fields to the shape of any tumour. This technology invites the reduction of beam margins in order to maximally spare healthy tissue, reducing side-effects, but placing more emphasis on the precision of dose delive...

    Illustrates the application of a 3D multiple dataset visualisation tool to a small relational database. The system itself is built around the concept of data containers. These are dynamic regions in 3D space which provide the ability to view multiple datasets using alternate visual paradigms in a dynamic visual querying environment. This system therefore proposes a technique for the exploration of... View full abstract»

    A CDM (cognitive design medium) is defined as a medium which supports the cognitive nature of design in computerized environments. We review the theoretical background and demonstrate the basis upon which an interactive counterpart can be achieved in supporting the cognitive capabilities of the designer, such as visual thinking. The approach is elaborated and illustrated by experimental work in th... View full abstract»

    The paper explores the research potential of a multimedia database called `Simulated Site Visits' to record the translation processes which occur between architectural documentation drawings and their built form. This is a significant area for research, as computer visualisation is transforming design and documentation techniques. `Simulated Site Visits' allows records of the construction process,...

    There is a lot of development currently being carried out on cooperative visualization via communication networks. User interaction is kept to minimum in this kind of development, such as only making marks on the transmitted images, etc. There is relatively less work being done on complicated cooperative interactions, especially real-time cooperative interaction via networks.

    Visualization enables `seeing the unseen', and provides new insight into the underlying data. However, users far too easily believe or rely on a single representation of the data; this view may be a favourite method, the simplest to perform, or a method that has always been used. A single representation may generate a misinterpretation of the information or provide a situation where the user is mi... View full abstract»

    Solid model abstraction is an integral part of parallel and process design. It is required for simulation and optimisation of the design and consists of retrieving a simplified model from the solid one, with appropriate dimension reduction and details removal. Unfortunately, current CAD systems do not provide the means for easy simplification of forms. Ongoing research efforts on abstraction yield... View full abstract»

    A number of 3D information visualization designs have been invented during the last few years. However, comparisons of such designs have been scarce, making it difficult for application developers to select a suitable design. This paper reports on a case study where three existing visualization designs have been implemented and evaluated. We found that the three information visualization designs h... View full abstract»

    Computer animators find that maintaining control of the shape of deformable objects during motion is sometimes difficult. This paper describes a system called “Gargoyle” which provides improved support in this area; it concentrates particularly on the form of interaction between user and computer. In Gargoyle, an object is sculpted at several predefined key positions which are associat... View full abstract»

    In order to simulate the correct behavior of light incident on a material, we must first understand the different interactions not only between the light and the surface of the material but also between the light and the inner structure of the material itself. Physical measurement is a way to record a material's behavior, but is limited to pre-existing objects and measurement conditions. Therefore... View full abstract»

    In our minds, we can create an imaginary environment of shapes and objects. A natural and intuitive way to externalize these imaginary shapes is through our hands by simply sketching or tracing their outline in space. If we could capture and then interpret our hand shapes, then we would be able to express spatial information in computer-generated graphical environments in a simple and extremely po...

    A significant amount of rework in construction is caused by clients' last-minute changes and their inability to acquire a realistic appreciation of the product from the 2D drawings at the design development stage. This paper introduces a computer system that enables a user to construct a 3D design model efficiently using object models stored in graphical element libraries. The system allows the us...

    The purposes of this research are to analyze and visualize some properties of aesthetic surfaces and to construct the shapes, which satisfy designers' intentions. To extract and visualize the properties, surface edges of a free-form surface were introduced. The edges are loci of the points that have the extremum values for characteristics of the surfaces such as curvature, height, brightness and s... View full abstract»

    A piecewise rational cubic spline curve has been described. The designed curve possesses parameters (weights) in each interval which can be used to control the shape of the curve. A very simple distance-based approximated derivative scheme is presented to calculate the control points. Also, for any interval, it is possible to calculate control points for intermediate point interpolation or conic c... View full abstract»
