    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...

    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»

    A thin client, by definition, has minimal software requirements necessary to function as a user interface front-end for a Web enabled application and raises the issue of client vs. server data visualization rendering. Real-time visual data manipulation does not translate well into a thin client. While the VRML file format allows distribution of visualization scenes to the Web, the user has no acce...

    The composition of 3D presentations is a complicated procedure partly facilitated by the introduction of VRML. VRML does not yet support 3D object storage and querying, thus introducing limitations to object reusability. Presentations have to be built from scratch while the necessary information already exists from previous work. This paper presents a method to address this issue by providing the ...

    There are many qualitative and quantitative techniques which have been used for a variety of cases of curve fitting, smoothing and forecasting. All but a few have considered curves from a shape-geometry point of view. The paper argues that curve geometry contains characteristics that are descriptive of the nature of the subject area and therefore provides a viable alternative for the generation of...

    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...

  • 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»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2000 KB)

    The use of neural nets with an associated learning paradigm was investigated for the purposes of animation control. Neural control schemes were set up and used to control simple skeletal figures. In most cases, the methods eventually converged to a controller that performed very well, even when the learning algorithm became trapped at local minima. However, there is a limit to the learning rate, o... View full abstract»

    This paper presents an algorithm for approximating the sky brightness of a clear sky with sunshine. The sky light and the light reflected from the ground are approximated by a finite set of parallel light beams. The long-term simulation is considered by averaging the radiance of the lights over a certain time period. The main area of interest of the method is considered to be, but is not restricte...

    It is often necessary to represent a hand-drawn shape accurately. Modeling such shapes manually is both cumbersome and commercially expensive. The user's concern for curves that are easy to manipulate has been a major influence on the development of free-form curves. Rational parametric curves have been receiving considerable attention in the area of geometric modeling because any parametric polyn... View full abstract»

    It has long been recognised by building surveyors that training a surveyor is both time-consuming and relatively risky. Universities and colleges recognise the difficulties of taking groups of students to inspect a property because of health and safety, insurance liability and organisational considerations. This paper proposes a solution to these problems by developing a virtual reality package th... View full abstract»

    Nowadays, constraint solvers play a fundamental role in many graphical applications, including geometrical and mechanical CAD systems, layouts, user interfaces and animation. These applications use constraints to conveniently describe the relations between objects. Constraints are automatically maintained and satisfied by a constraint solver. So, numerical and tedious tasks are left to the solver ... View full abstract»
